Rock Transformations

You have 2 rocks formed at the same time. One rock was formed from small pieces of rock and the other was formed from liquid rock in a different place. Would these rocks be the same or different types of rock? Why?

• the same type because they are both formed from rock material.

• the same type because they formed at the same time

• different types because they formed in different ways

• different types because they formed in different places

Energy from the sun causes rocks to be weathered and broken into smaller pieces called

• magma.

• rocks.

• pebbles.

• sediment.

Sedimentary rock is formed when

• rock moves beneath the surface of Earth, is melted into magma, then cooled to form rock.

• energy from the sun causes rock to be weathered, broken into sediment, and then compacted and cemented together to form rock.

• rock moves above Earth's surface and is exposed to energy from Earth's interior.

• energy from Earth's interior causes the sediment to melt and form rock.

How could rock from a rock formation turn into sand?

• Rays from the sun shone down on the rock, and it broke into pieces.

• If anything were left out for a long time, it would break into small pieces.

• The sand was formed by earthquakes, tsunamis, and other natural disasters. These disasters were strong enough to break rock into small pieces.

• Wind and rain interacted with the rock, breaking it into small pieces.
