Rock Transformation

If one rock is formed from small pieces of rock. Another rock is formed from liquid rock in a different place. Both rocks formed at about the same time. Are the rocks the same or different types of rock?

• different types because they formed in different ways.

• the same type because they formed at the same time.

• different types because they formed in different places.

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

A rock sampled is an igneous rock. Could the material that it formed from was part of a sedimentary rock formation millions of years ago?

• 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.

• No, igneous rock can only form from other igneous rock. Sedimentary rock cannot change into 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 forms under Earth's outer layer due to energy from Earth's interior, but sedimentary rock only forms at Earth's surface.

How can energy play a role in the different types of rock that form?

• Energy changes rocks on different continents in different ways. Each continent on Earth has different rock that might form liquid rock or small rock pieces when exposed to energy.

• Energy caused one rock type to form, but not the other. Rock that forms because of energy is a different type of rock than rock that forms without energy.

• Energy causes different types of rock to change in different ways. Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock.

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

How does rock material from a rock formation turn into sand?

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

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

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

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

How does metamorphic rock form?

• It melted and cooled.

• It broke into sediment and then compacted.

• It was heated and put under pressure.

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

Will rocks change in one week's time?

• The rock is not likely to change very much. Most rock formation processes happen very slowly.

• The rock will probably change a lot. Rock is always changing and transforming.

• The rock might change if it is the right season.

• The rock will not change at all. Rock just stays as it is.

Two continents are close to each other but they used to be far apart. What happened?

• The plates hit each other and broke into pieces, creating sand.

• One plate went underneath the other plate and sank into the ocean below.

• One plate went underneath the other plate and sank into the soft rock below.

• The plates pushed against each other, causing the edges to bend upward.

How do small pieces of rock break off mountains?

• The small pieces of rock were formed by earhtquakes, tsunamis, and other natural disasters.

• 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.

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

Can an igneous rock formation turn into a sedimentary rock formation?

• Yes, if energy from Earth's interior can cause igneous rock to break into small rock pieces that form sedimentary rock.

• No, sedimentary rock forms at Earth's surface because energy from the sun causes rock to weather, but igneous rock under Earth's outer layer is not exposed to energy from the sun.

• 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.

• No, sedimentary rock can only form out of material from other sedimentary rock. There is no way that sedimentary rock can form from material in igneous rock.

Can material in igneous rock become sedimentary rock? Can material in sedimentary become igneous rock?

• Yes

• No
