What is the role of energy in rock formation?

Back

Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, while energy from the sun causes rock to weather into small pieces.

Front

Can igneous rock material form sedimentary rock?

Back

Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock.

Front

How does metamorphic rock like gneiss form?

Back

Metamorphic rock forms when existing rock is heated and put under pressure.

Front

What distinguishes sedimentary rock from igneous rock?

Back

Sedimentary rock forms from small pieces of rock, while igneous rock forms from liquid rock that cools.

Front

What happens to tectonic plates when they collide?

Back

When tectonic plates collide, they can push against each other, causing the edges to bend upward or one plate may go underneath the other.

Front

What is the definition of igneous rock?

Back

Igneous rock is formed 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.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed from existing rock that has been changed by heat, pressure, or chemically.

Front

What is weathering in geology?

Back

Weathering is the process by which rocks are broken down into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation and transformation, including the formation of igneous, sedimentary, and metamorphic rocks.
