Amplify Rock Transformation Review

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.

Can igneous rock be formed from rock that was once sedimentary rock?

• Yes, if sedimentary rock is exposed to energy from the sun at Earth’s surface for a long enough time, it can melt into liquid rock and form igneous rock.

• Yes, if sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form igneous rock

• No, igneous rock can only form from other igneous rock. Sedimentary rock cannot change into igneous rock.

• No, igneous rock forms under Earth’s outer layer due to energy from Earth’s interior, but sedimentary rock only forms at Earth’s surface.

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.

How is a metamorphic rock formed?

• Rocks don’t form; they stay as they are.

• by melting and cooling

• by being broken into sediment and then compacted.

• by being heated and put under pressure.

What type of rock is formed when pieces of rock have been compacted and cemented together?

• sediment

• igneous rock

• metamorphic rock

• sedimentary rock

Energy from the Eath's interior causes rock to melt and form magma. What type of rock forms when magma is cooled?

• igneous rock

• lava

• sedimentary rock

• metamorphic rock
