FCHS Earth Systems: SES3.a Flashcard

Front

What natural process is responsible for weathering rock when water freezes?

Back

Water expands when it freezes.

Front

How does surface water contribute to the formation of caves?

Back

Surface water reacts with limestone, dissolving it over time.

Front

What is the best method to observe the effects of acid rain on limestone?

Back

Weigh limestone samples before and after exposure to acid rain.

Front

In what way does groundwater contribute to chemical weathering?

Back

By dissolving minerals in rocks.

Front

What role do animals play in the weathering process?

Back

Animals can contribute to physical weathering by burrowing.

Front

Define weathering in the context of Earth systems.

Back

Weathering is the process of breaking down rocks and minerals through natural processes.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks.

Front

What is physical weathering?

Back

Physical weathering is the mechanical breakdown of rocks without changing their chemical composition.

Front

How does acid rain form?

Back

Acid rain forms when sulfur dioxide and nitrogen oxides react with water vapor in the atmosphere.

Front

What is the impact of acid rain on limestone?

Back

Acid rain can dissolve limestone, leading to the formation of features like caves.
