Why is sedimentary rock important in the study of earth's history?

Answer 1

Sedimentary rock provides evidence of the history of rock. But how? It's very simple. There are different layers of earth piled on top of each other. They may contain fossils or other organic materails. Scientists study the layers of the Earth and do that by looking at the soil and rock. The type of sediment in different layers will, of course, be different. Therefore, scientists can figure out about the type of year or years that the occupants of the Earth had.

Answer 2

Over time, layers of sediment settle on top of other layers, creating a strata or collection of layers, the oldest layers at the bottom and the newest at the top. By studying the materials and structure in each layer, scientists can determine a little of what was going on at the time a layer was being formed (similar to how the rings on a tree show how it lived when the ring of bark was formed). Layers that contain certain types of minerals may indicate how much water was being transported, what gases were present in the air, or whether any volcanoes were adding ash to the environment. Dead organisms trapped in sediments are sometimes represented as fossils, leaving impressions in the stone.

Answer 3

Sedimentary rocks contain valuable information about past environments, climate conditions, and the evolution of life on Earth. By studying sedimentary rocks, scientists can reconstruct Earth's history, including the movement of continents, changes in sea level, and major geological events that have occurred over millions of years. This helps us understand the processes that have shaped our planet and provides insights into future environmental changes.

Answer 4

eras and then smaller periods based on geologic and biologic events that occurred during those times

Answer 5

it shows earths history by how deep it was in the earth and with how compressed it is

Answer 6

It is used to write on and keep tabs on.
