Rocks and other sands that get worn down by the water going back and forth

rock and smaller rock and erosion

Dawson,G said...

Rocks that have broken from water shifting the rocks and breaking and winding up on shore.

Dominique G. and Bryn W. said...

Materials that make up beach sand vary. Some hings are broken up pieces of shells, sometimes small broken pieces of rock, also "Salt". It gets here from erosion. Wind can carry this mixture of things just as much as water can.

Maddy C. said...

Rocks and other things probably get broken up and make the sand. The materials might come from the water.

James D said...

Smaller rocks that break and break and break????

Quartz, the most common mineral, is composed of silicon dioxide, while feldspar, the second most common mineral, is made up of sodium, calcium, or potassium combined with silica.

Much of the extraneous material on beaches is found in drift lines (wrack lines) which are the linear piles of natural and man-made objects that are left behind at the uppermost limit of the wave swash. The positions of the drift lines are a good indicator of the high tide or storm wave limit.

Sand is a loose, fragmented, naturally-occurring material consisting of very small particles of decomposed rocks, corals, or shells. Sand is used to provide bulk, strength, and other properties to construction materials like asphalt and concrete. It is also used as a decorative material in landscaping. Specific types of sand are used in the manufacture of glass and as a molding material for metal casting. Other sand is used as an abrasive in sandblasting and to make sandpaper.

Beach materials can be made of sand, pebbles, cobbles, or boulders. The rocky cobble beaches of Acadia National Park, Maine are the result of the progressive erosion and weathering of coastal bedrock under strong wave action.
This change can be a natural feature such as dunes or a cliff, or a humanmade structure such as a seawall.

Generally beach sediments are made up of rock material that has been eroded from inland and carried by rivers to the ocean (being further eroded to smaller particles and chemically altered in many cases) where they are deposited on the beach. There are some special cases where material is being deposited from some other source, such as the green beaches in Hawaii (the result of offshore volcanic producing large amounts of olivine which wash ashore and make up the bulk of the sand.

In a very general sense you can think of it as rock being formed and forced to the surface, either by volcanic activity or mountain building, this rock is then eroded by various processes including physical erosion from wind, rock fall, freeze/thaw cycles, etc, and to a lesser extent chemical weathering from rain water dissolving elements and in some cases oxidation. Once the rocks reach a point where they are no longer stable they fall into mountain streams and rivers and are then carried downstream (larger rocks like boulders generally continued to be weathered and breakdown further before moving because the river is not powerful enough to move the entire rock).

These sediments travel with the river downstream, either in the bedload (sediments rolling on the bottom), suspended load (sediments that are small and low density enough to float at various levels in the water and don't hit the bottom) and dissolved load (elements are dissolved in the water such as sodium and chloride (dissolved salt)). Sediments in the bedload and suspended load are continuously eroded by colliding with the bottom and other particles, causing sharp edges to dull and ending up with smooth round surfaces. The further sediments travel the smaller, smoother and rounder they become so you can tell how far (and how old) sediment is by how FROM wiki

clay and mud and water.

-I think that the rocks on the land washed the rocks down near the beach. And the rocks got so warn out by the waves and the salt.
-The materials that end up on the beach is small rocks that get smaller every time the waves and the salt get to the rocks.

Zach S. said...

It's small rock's, sand and a type of salt. I think it gets there from wind and the waves bringing more and more until it forms a beach.

Connor.R said...

A beach is a landform along the shoreline of an ocean, sea, lake or river. It usually consists of loose particles which are often composed of rock, such as sand, gravel, shingle, pebbles or cobblestones. The particles comprising the beach are occasionally biological in origin, such as mollusc shells or coralline algae.

Wild beaches are beaches which do not have lifeguards or trappings of modernity nearby, such as resorts, camps and hotels. They are sometimes called undeclared, undeveloped or undiscovered beaches. Wild beaches can be valued for their untouched beauty and preserved nature. They are most commonly found in less developed areas including, for example, parts of Puerto Rico, the Dominican Republic, Thailand, the Philippines, and Indonesia.

Bangladesh is the home of the world's longest natural sandy sea beach, located at Cox's Bazar.

Beaches typically occur in areas along the coast where wave or current action deposits and reworks sediments. http://en.wikipedia.org/wiki/Beach

good job Jordan M

Garrett H said...

I think that beach sand is made up of different sized rocks that had been broken down into smaller sediment from the water hitting it until it is broken down into really fine sediment.

nobody nowwwwww said...

when a rock goes to a bottom of the lake it turns in to sand.

NOBODY KNOWWWWWSSS said...

Lauryn Silva said...

I think rocks get ground up from the water and all of the sediment that was in the rocks flow out of the rock while it is being ground up by the salt in the water. The ocean has control to carry the sediments from the rocks that are getting ground up and are eroding to the surface/land.

Allison A said...

I think that rocks break up from the salt water and it breaks up the rocks.I think the reason why the sand and other things end up on the beach is because the water pushes and pushes the water on to the beach and it builds up.

WHO ARE UUUUU?????

Eroded rocks that is the material that makes up a a beach

i think the water breaks up the rcks that turn into sand and the water pusges it on to the beach

SMITTY (EVAN) said...

the things that make the beach sand or fine rock partials

jg123 said...

salt and dirt

z said...

i think it gets there from the what it builds up then go's on the beach.

gold,black sand,minerals,

The Sand is made of little pebbles and it got there from erosion.

EmilyB said...

I think the materials that make up beach sand is little crushed up rocks. There can also be seashells. They can end up on the beach by the waves going into shore, then they stay there for kids to find them.

Cassidy m said...

The beach sand is made of ummm...sand and maybe rocks i guess....and ummmmm they get washed up there???

MorganD said...

????????????

Katie L. said...

The sand is made of rocks that are eroded. They are carried by bodies of water and then deposited on the beach.

old pieces of broken ship pieces and other ancient artifacts plus rocks sand and other particals.

catie.r. said...

i think that deteriated rocks make up sand and i think that it ends up on land by washing up on shore by the ocean.

ALice M. said...

Rocks, sand, and gravel, also stuff like crab and lobster shells all make up the the shoreline . These materials get there when the ocean leaves it there when the tide throws it up.. so to speak.

Aasyhia said...

I think that huge rocks wee broken down or eroded into little tiny particles of sand they got there by from erosion moving from one place to another

Carly M. said...

I think the materials that make up beach sand are rock that have worn away over the years. One of the rocks that break down into sand is quarts
These materials end up on the beach by the wind and the tide.

Jasmine B said...

Materials i think make up the beach are things that have been broken up, like sand, rocks, crab shells and stuff like that....
how these materials end up on the beach are from mostly erosion, like sand is basically eroded limestone. things will be eroded and washed up on the surface by the water.

joe w said...

erroded rock and dried sediments

ConnorB said...

I think the materials on a beach are made up of rock broken down by the waves and current of the ocean. I think the ocean is responsible for for the minerals on the beach, I think that the high tide leaves the broken up rock and sediment on the beach.

Parker D. (XDMee:3) said...

I think crushed up seashells and rocks make up the sand. They get there by washing up onto the shore.

Kevin S said...

a rock throug a lot of years of abrasion and water washes it up on shore

AndrewE said...

I think the beach is made up of crushed coral and crushed rock that has been washed up by the waves. The waves wash up the rocks and they crumble them when the waves crash.

Owen R !! said...

The sand is made up of little bits of rock sediment.

Zachk said...

I think that broken down rocks created the sand. The rocks were broken down by water, then washed ashore.

Maddy P. said...

I think the materials that make sand on the beach are made up of broken down rocks from the waves and the current of the ocean. I think the materials end up on the beach from having the waves and current bring the broken up sediment to the beach.

Matt C said...

rocks that get erodid by the ocean

Journey B. said...

I think the sand is made of little pebbles, or broken down rock. The rock wares down so much that it forms these little grains of sand. There are also other materials in it like shells and seaweed from the ocean. Sand is mainly just small pieces if rock.

It could have come from previous rocks on the beach being worn down from wind and water erosion. Or, the rocks could have been brought in with high tide, then eroded.

Kaylee C. said...

The material are made up of small rocks.


They get there because the wind and stuff like that.

Nathan C. said...

Quartz get grinded underwater and end up on the beach

Shane k said...

Rocks smashing against the shore and breaking down into sand, and I think the rocks come from the waves in the sea.

Whitney R said...

I think small pebbles and wet dirt but not mud make up sand on a beach.
I think they just kind of move and flow onto the beach and from under the ocean as it is washed up.

Aidan R said...

I think that little tinny rocks make up beaches. I also think that they got there bye the ocean breaking away bigger rocks.

david vincent said...

Little tiny rocks make up beaches.
The water carries the sand from the ocean floor and carries it to the surface.

Kelsey S. :P said...

I think that beach sand is made of rock that were at one time kinda big but then the water kinda made the rock dissolve, and smooth!

Emily H said...

The sand that ends up on the beach is rocks that have been beaten down til it was sand and that was in the ocean and it got washed up to land on the beach.

I think that the materials that make up the beach sand were solid and bigger objects that are broken down such as rocks.

I think the materials have always been on the beach and just broken down over a long period of time.

Arlo P said...

I think beach sand is made up of rocks and really small grains of sand. These materials end up in the beach by boulders being eroded by wind and other eroding forces. Slowly they get eroded and become lighter and easier to be thrown around.

Zoe D said...

I think beach sand is made of worn down rocks and pebbles. The materials end up on the beach by the ocean bringing rocks on the beach and over time the waves break it down.

Mara C. said...

I think the materials that make up the sand on the beach are granite rocks because when the rock hit other rocks and the rocks starts to chip of pieces and creates sand.

jenn w said...

materials i think make up the beach rocks because the rocks starts big then get smaller and smaller and smoother.

how it end up on the beach is when the tied comes in the ocean brings these materials on to the beach.

Skyler D. said...

I think that when rocks rub off of each other they will detereate into sand and when the water sways back and forth it will make it into a beach because there is to much sand for it all to go back and forth.

Hayley G said...

i think that beach sand is made up of rocks that were beaten down to littler rocks.And also other things like shells that were worn down by the ocean and people.

Jenny C said...

Mia W said...

The materials that I think make up of broken up rocks, sand, dust, crab shells that have been emptied by seagulls and a whole bunch of other stuff that I probably don't know about. I think these things end up here by the sand blowing dust from other places to the beach, the tiny rocks probably come from construction sites or local places that rocks have been smashed up and everything. And well the crab shells could come from the seagulls that got really hungry and they wanted to eat so they found the crabs and ate them. Sand is made up of a whole bunch of different stuff so you can't really tell just by looking at it. Those are some stuff materials that I know that make up a beach.

Jacob G said...

Water from the body of water that the beach is on erodes the big rocks in the body of water down to little rocks or pebbles. And they get on the beach by the tide with the other stuff on the beach did the same. The rocks on the beach are made of a lot of different materials.

Lauryn R said...

I think that the materials that make up beach sand is really small pebbles and sand the materials have always been on the beach but just broke down into smaller pieces and that have been washed onto shore over time.

Damian P 8) said...

what materials are on a beach are broken up things like rocks, animal shells and sand.
How these materials end up on the beach is because current and waves carry the them to the beach also how the sand gets so high upon the beach is because of high tide.

Morgan S said...

Materials from a beach are sand shells and water. The water of course comes from the ocean. But the sand is broken up shells and rocks material. The shells are broken up by weathering that would happen to that beach.

The materials end up on the beach because they are washed up onto the shore because the water will carry them in. And then when the water goes away it is left there.
