What are some of the major events in the 4.6 billion year geological history of Earth? What evidence could be found in rock strata that would support the occurrence of major events in the geological history of Earth?
From the point at which the planet first began to form, the history of Earth spans approximately 4.6 billion years. The oldest known rocks—the faux amphibolites of the Nuvvuagittuq greenstone belt in Quebec, Canada—however, have an isotopic age of 4.28 billion years. There is in effect a stretch of approximately 300 million years for which no geologic record for rocks exists, and the evolution of this pregeologic period of time is, not surprisingly, the subject of much speculation. To understand this little-known period, the following factors have to be considered: the age of formation at 4.6 billion years ago, the processes in operation until 4.3 billion years ago, the bombardment of Earth by meteorites, and the earliest zircon crystal
Some of the major events in the 4.6 billion years that Earth has existed are reptiles and flowering plants becoming existent, dinosaurs going extinct, and Pangea forming then breaking apart. Evidence of fossils of extinct species of animals and plants found in rock strata would support the occurrence of major events in the geologic history of Earth.
4.6 billion years ago all of the dinosaurs went extinct. And animals started to enter the world. The evidence for that is that there is fossils to find under the ground, you can easily check out the fossils to see when they went extinct.
Some of the Evidence that we could see to show us some major events could be That the one of the rarest rocks were Fund on the surface of the earth so It's ideal that the Rock came from outer space

It is widely accepted by both geologists and astronomers that Earth is roughly 4.6 billion years old. This age has been obtained from the isotopic analysis of many meteorites as well as of soil and rock samples from the Moon by such dating methods as rubidium–strontium and uranium–lead. It is taken to be the time when these bodies formed and, by inference, the time at which a significant part of the solar system developed. When the evolution of the isotopes of lead-207 and lead-206 is studied from several lead deposits of different age on Earth, including oceanic sediments that represent a homogenized sample of Earth’s lead, the growth curve of terrestrial lead can be calculated, and, when this is extrapolated back in time, it is found to coincide with the age of about 4.6 billion years measured on lead isotopes in meteorites. Earth and the meteorites thus have had similar lead isotope histories, and so it is concluded that over a period of about 30 million years they condensed or accreted as solid bodies from a primeval cloud of interstellar gas and dust—the so-called solar nebula from which the entire solar system is thought to have formed—at about the same time.

We study our Earth for many reasons: to find water to drink or oil to run our cars or coal to heat our homes, to know where to expect earthquakes or landslides or floods, and to try to understand our natural surroundings. Earth is constantly changing—nothing on its surface is truly permanent. Rocks that are now on top of a mountain may once have been at the bottom of the sea.

The first major event from the beginning of our solar system is the Big Bang, when our solar system was formed from solar debris. Evidence is that millions of astroids and other debris still floating around in space from the Big Bang.
3800 million years ago the earliest life was discovered. Fossils found at a point and behind that there was no evidence of life is supporting this fact.

ReplyDeleteDinsoaurs being exctinct. The dinos fossils are in the ground somewhere.

ReplyDeleteDinasours died out, the bones/fossils are everywhere on the earth except for the oceans.
ReplyDeletePangea started to slit apart.
ReplyDeleteone of the examples is the dinosaurs going extinct and very old rocks are still on the earth.
ReplyDeletethe dinosaurs dieing (exctint) then the the dinosaurs bones are in the ground and u have to find them
ReplyDelete200 million years ago the Earth had it's first birds and bees, and plants began to flower.
ReplyDeleteSome of the major events in the 4.6 billion years that Earth has existed are reptiles and flowering plants becoming existent, dinosaurs going extinct, and Pangea forming then breaking apart. Evidence of fossils of extinct species of animals and plants found in rock strata would support the occurrence of major events in the geologic history of Earth.
ReplyDeleteOrganic evolution this is proven by any type of fossil.
ReplyDeleteThe Ice Age occurred in the latest Era and Scientists have found Mammoth Tusks in the most recent layer of rock.

ReplyDeleteDinosaurs were going extinct and finding them.

ReplyDeleteDinosaurs went extinct and evidence in the strata would be shells, bones, fossils etc.

Some big events are dinosaurs and The first humans

In the mesozoic era the humans came to be.

ReplyDeletewe can find evidence of dinosaurs today

ReplyDeletesome major events were simply just the dawn of the dinosaurs.
ReplyDeleteDinosaurs went extinct and there are fossils of them in the ground.
ReplyDeleteLots of stuff happened in the past years and dinosaurs are now extinct.
ReplyDeleteFossils are something you could find in the rock strata.
ReplyDeleteMajor events in Earths history are events affecting the surface of the Earth and the evolution and extinction of life forms.
ReplyDeleteDinosaurs going extinct you just have to find the bones in the ground and look around theres no more dinosaurs around.

ReplyDeleteDinosaurs roamed the land, and they died, going extinct.
ReplyDeletea big meator hit and all the dinosaurs are dead
ReplyDeletefind the bones you find out when it lived and died
