Science Flashcard

Front

How does magma form?

Back

Magma forms by the melting of rock deep in the Earth.

Front

How are caves and sinkholes formed?

Back

Caves and sinkholes are formed when limestone is slowly dissolved by weak carbonic acid in groundwater.

Front

What is true about the Earth's crust?

Back

The oceanic crust is more dense and thinner than continental crust.

Front

Who feels earthquake vibrations first?

Back

Person 2 would feel the vibrations from the earthquake first.

Front

What is the cooling rate for extrusive rocks?

Back

Extrusive rocks cool quickly, resulting in small grains; for example, obsidian.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is denser and thinner compared to continental crust.

Front

What is the process of lithification?

Back

Lithification is the process where sediments compact under pressure and cement together to form sedimentary rock.

Front

What role does pressure play in metamorphism?

Back

Pressure realigns minerals in rocks, leading to metamorphism.

Front

What is the composition of magma?

Back

Magma is composed of molten rock, gases, and mineral crystals.

Front

What is the significance of carbonic acid in geology?

Back

Carbonic acid, formed from carbon dioxide and water, plays a crucial role in the weathering of limestone.
