LAB FLASHCARD Ch 5.1 Virtual GIZMO Weathering

Front

What is chemical weathering?

Back

Chemical weathering is the process where minerals in rocks are changed through chemical reactions, often involving water and atmospheric gases.

Front

What type of rock is granite?

Back

Granite is a very hard igneous rock formed from the crystallization of magma deep underground.

Front

Which rock weathers most quickly?

Back

Shale weathers most quickly compared to granite, sandstone, and limestone.

Front

How is shale formed?

Back

Shale is formed from the compaction of mud.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process where rocks are physically broken down or worn away without changing their chemical composition.

Front

What is the primary agent of chemical weathering?

Back

Water is the primary agent of chemical weathering, facilitating chemical reactions that alter minerals.

Front

What role do temperature changes play in weathering?

Back

Temperature changes can cause rocks to expand and contract, leading to mechanical weathering.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks in place, while erosion involves the movement of weathered materials from one location to another.

Front

What is the significance of soil formation in weathering?

Back

Soil formation is a result of weathering processes, providing nutrients for plants and supporting ecosystems.

Front

What is the effect of acid rain on weathering?

Back

Acid rain accelerates chemical weathering by increasing the acidity of rainwater, which can dissolve minerals in rocks.
