Rock Transformations Quiz

Are Rocks A and B the same or different types of rock?

• 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.

How could energy have played a role in the different rock types forming?

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

• 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 changes rock in different ways, depending on the starting rock type. Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock.

• Energy changes rock 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.

Could the material for igneous rock come from 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.

How did material from the rock formations 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 did this metamorphic rock form?

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

• It melted and cooled.

• It broke into sediment and then compacted.

• It was heated and put under pressure.

Are Rocks A and B the same or different types of rock?

• different types because they formed in different ways.

• different types because they formed in different places.

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

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

How could energy have played a role in the different rock types forming?

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

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

Is it possible that material from this rock formation could ever form sedimentary rock on Earth’s surface?

• 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.

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

• 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.

What would you tell Giovanni about how the rock will change?

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

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

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

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

Which diagram above shows what happened to the plates that Africa and Europe are part of?

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

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

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

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