Earth Science Flashcard

Front

What can change rock inside of the Earth?

Back

Heat and pressure.

Front

What happens to hot material at mid-ocean ridges and deep sea trenches?

Back

Hot material rises at mid-ocean ridges and sinks at deep sea trenches.

Front

How are rock layers ordered from oldest to youngest?

Back

The correct order is 5, 4, 3, 2, 1.

Front

How are extrusive rocks formed?

Back

Extrusive rocks are formed from lava cooling and solidifying on the Earth's surface.

Front

What can scientists infer if they find a fossil?

Back

They can infer that water once covered the area.

Front

What is the process of erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water.

Front

What is the difference between intrusive and extrusive rocks?

Back

Intrusive rocks form from magma cooling slowly beneath the Earth's surface, while extrusive rocks form from lava cooling quickly on the surface.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation through processes like melting, cooling, erosion, and compaction.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

What is the significance of fossils in geology?

Back

Fossils provide evidence of past life and can indicate the environmental conditions of the Earth at that time.
