Unit 4- Investigating Earth's Changes

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock that is formed from the accumulation and compaction of sediments, which can include minerals, organic matter, and fragments of other rocks.

Front

How do layers of sediment on the ocean floor form sedimentary rock?

Back

The weight of the ocean compacts the sediments into rocks.

Front

What are U-shaped valleys?

Back

U-shaped valleys are valleys that have a characteristic U shape, formed by the erosion of glaciers.

Front

What natural process forms U-shaped valleys?

Back

Glaciers.

Front

What is deposition in geology?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass.

Front

How does deposition change the Earth’s surface?

Back

Deposition changes the Earth’s surface because bits of broken rock and soil are dropped in new places.

Front

What is the difference between weathering and erosion?

Back

Weathering is the process of breaking down rocks into smaller pieces, while erosion is the movement of those pieces from one location to another.

Front

What is weathering?

Back

Weathering is the process by which rocks are broken down into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by natural forces such as water, wind, or ice.

Front

What is sedimentation?

Back

Sedimentation is the process of settling or being deposited as sediment.
