The rock cycle is the proces of breaking and changing rocks. Mechanical and chemical weathering change rocks.

Mechanical and chemical play a huge role in the rock cycle!

Samantha L said...

Weathering is a huge part of the rock cycle! It breaks down the rocks!

mechanical and chemical are very important

Brendan S said...

Mechanical and weathering are a huge piece of the rock cycle, cause they both change rocks.

Taylor J said...

What I know about the rock cycle is that mechanical and chemical weathering really matter.

Rylan N said...

weathering breaks down the rocks into sand and thats part of the rock cycle.

i Know all of it

The rock cycle is a process of breaking and changing rocks. Mechanical and chemical weathering play a big part in the rock cycle.

Mechanical and chemical weathering break down rocks. The rock cycle is the life of the rock and what happens in its cycle. They are huge parts of the rock cycle.

Cassidy R. said...

The rock cycle is the natural process in which rocks transform from one rock type into another rock type over time, a type of natural recycling.

Evan L said...

Mechanical and chemical weathering both help to break down rocks.
I also know that the rock cycle is the breaking down of rocks.

Mechanical and Chemical weathering play a huge role in the rock cycle, It breaks down the rocks.

the rock cycle is when the rocks break.

Wyatt R said...

I know that Mechanical and Chemical Weathering are part of the rock cycle. They play the role of breaking down rocks.

Casey K said...

The rock cycle breaks down the rocks and mechanical and chemical weathering change the rocks

Tyler J said...

weathering is a pretty big part of the rock cycle it breaks down rocks and changes there shapes

Mya N said...

Weathering is a huge part of the rock cycle. Weathering breaks down rocks

Katie N. said...

In weathering rocks get changed, they get broken down. Chemical and Mechanical play very important roles.

Leslie K said...

The rock cycle is a continuos process and it happens over millions years. Weathering is one of the first steps of the rock cycle and it's really important.

Mechanical weathering is hitting rocks of rocks and chemical weathering is ice,water,sunlight,cold.

Ben S. said...

Chemical Weathering and Mechanical Weathering are a big part of the rock cycle.
Also, there are three types of rocks, sedimentary, igneous, and metamorphic. :)

Ella T. said...

Chemical and mechanical weathering plays an important part in the rock cycle because they are both the process of breaking down rocks, and breaking down rocks is part of the rock cycle, and if we didn't have weathering, we wouldn't have many rocks on the planet...

Julia M said...

Mechanical and chemical weathering is a big piece of the rock cycle, because they both change rocks.

weahterong is a HUGE part of the rock cycle it helps break down rocks

Weathering is an important part of the rock cycle because it breaks down rock and changes it's shape

Erin W said...

Weathering is a big part of the rock cycle. Mechanical weathering is physical damage to the rock and and chemical weathering is when chemicals break down the rocks.

I know that mechanical and chemical weathering have a huge part in the rock cycle. the rock cycle is the process of rocks being broken down.

Blaze H said...

Chemical and Mechanical is the breaking down of rock, which is the large part of the cycle. It changes rocks sizes and shapes. The rock cycle happens over millions of years, it's pretty cool that weathering could happen in a day, or in a year.

Lauren S said...

weathering is a big part of the rock cycle it changes the shape of the rocks around it.

the rock cycle is very impotant because it break down rocks and chand ito stuff and shapes

Rocks on the surface of the Earth are attacked by weather, which breaks them down. What is this process called? It's actually called weathering, for once a name in science that really makes sense! Rocks are exposed to air, moisture, and even living things that cause them to break down into sediment (loose particles). This process takes place near or at the surface of the Earth. One special thing that you need to remember about weathering is that it only covers breaking down the rocks, not moving the material it loosens from the rocks (for more on moving this material, see erosion).

chemical weathering breaks down the rocks and mechanical weathering makes minerals

NOAH L Weathering is a big part of the rock cycle it changes the shape of the rocks around it.

Patrick H said...

Chem and Mech weathering play a role by breaking down the rocks and then they go into the ground.

Cody M. said...

Adrian K said...

Both chemical and mechanical weathering are part of the rock cycle.

Jennifer C said...

Mechanical Weathering and chemical weathering break down rocks, therefore they are a huge part of the rock cycle.

Sophia S said...

I know that chemical and mechanical weathering are 2 parts of the rock cycle. Mechanical weathering is physical weathering and chemical weathering works trough chemical reactions to change the rock.

chemical and mechanical both are part of the rock cycle and both break down rocks

the rock cycle shows the way rocks are formed destroyed and rebuilt. Mechanical and chemical weathering has the effect of breaking down the rocks, turning them into sediments, eroding them and making them become a sedimentary rock.

The rock cycle is the breaking down of rocks and the recreation of rocks. Mechanical and chemical weathering breaks down the rocks into sediment that creates sedimentary rocks

Devon Sargent said...

chemical and mechanical weathering do have a huge part in the rock

AutumnP said...

In the rock cycle weathering and erosion show how rocks break down and get formed and moved

mechanical and chemical weathering do have a big part in the rock cyle because they effect the rock.

lindseyb said...

Mechanical and chemical weathering break down rocks and thats is a big part of the rock cycle.

Abbie N said...

The rock cycle is the way rock is broken down and constructed again. Weathering is included in the rock cycle cause it help breaks down rocks.

AutumnP said...

So chemical and mechanical weathering would play a part in that.

The rock cycle shows what rocks go through. Mechanical and chemical weathering breaks down the rocks. They are important in the rock cycle.

It breaks down the rock and stops there from being all giant rocks everywhere.

mechanical weathering and chemical weathering brake down the rock !

The rock cycle is a continuing chain of rock breaking and reconstructing.
