Rock Formations Multiple Choice

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often causing one plate to be forced below the other, leading to geological features like mountains or trenches.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How does igneous rock form?

Back

Igneous rock forms from the cooling and solidification of molten rock (magma or lava).

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles, often in layers.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed when existing rocks are subjected to heat and pressure, causing physical and chemical changes.

Front

Can sedimentary rock become igneous rock?

Back

Yes, sedimentary rock can melt and become igneous rock if it is subjected to high heat and pressure.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation, involving igneous, sedimentary, and metamorphic rocks.

Front

What is the difference between intrusive and extrusive igneous rock?

Back

Intrusive igneous rock forms from magma that cools slowly beneath the Earth's surface, while extrusive igneous rock forms from lava that cools quickly on the surface.

Front

What role does pressure play in the formation of metamorphic rock?

Back

Pressure causes the minerals in existing rocks to realign and change, leading to the formation of metamorphic rock.

Front

How long does it take for rocks to change?

Back

Most rock transformations happen very slowly, often taking thousands to millions of years.
