Earth Science: Semester 2 Test

Front

What can be assumed about rock layers that match in nearby geologic columns?

Back

The layers formed at about the same time.

Front

What happens as a result of a global increase in temperature?

Back

More water vapor begins to be stored in the atmosphere.

Front

If Range A has deeper and more developed soils than Range B, what can be inferred?

Back

Range A is likely older because it had more time to develop soils.

Front

What can hard rock like granite be turned into as a result of chemical weathering?

Back

Sediment.

Front

Why is the land surface rising after a massive ice sheet melted?

Back

The ground is rebounding upward because the weight of the ice has been removed.

Front

What is the process called when rocks break down into smaller pieces?

Back

Weathering.

Front

What is the term for the movement of sediment from one location to another?

Back

Erosion.

Front

What is the main cause of global warming?

Back

Increased greenhouse gas emissions.

Front

What is the significance of permafrost in climate change?

Back

Melting permafrost releases methane, a potent greenhouse gas.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken pieces.
