Georgina is a rock collector. She is looking at some information about two of the rocks she has collected on her travels. The information is as follows:

Rock A formed from small pieces of rock.

Rock B formed from liquid rock in a different place. Rocks A and B formed at about the same time.

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

The rocks are

the same type because they 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.

Hank passes by a building every day on his way to school. He notices that the rock used to build the walls of the building is a different type than the rock used to build the steps. 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 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 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.

A geology student describes a rock sample she is studying in class. The rock sample is igneous rock, but the student wonders if the material that it formed from was part of a sedimentary rock formation millions of years ago. Could this be correct? 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 rocks. 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.

On the island of Hawaii, Keanu notices that the sand on the beach is black, the same color as the rock formations on the island. Keanu realizes the sand used to be part of the rock formations. 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 the rock into small pieces.

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

Answer explanation

Tsunami's and Hurricanes create massive wind events that can break rocks down

On vacation at a lake, Saira’s mom sees an interesting-looking rock formation. Saira just learned about rocks in geology class and tells her mom that the formation is made of gneiss, a type of metamorphic rock. 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.

Answer explanation

Return to the Rock Transformation Simulation from the unit and make gneiss by analyzing the rocks and watch how you can form this metamorphic rock.

Geologists in Egypt and Ethiopia are comparing rock samples from rocks found in the two countries. They are sharing information about the rocks to figure out whether they are the same or different types of rock. The information is as follows:

Rock A formed from small pieces of rock. Rock B formed from liquid rock in a different place. Rocks A and B formed at about the same time.

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

The rocks are

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.

Geologists have evidence of an igneous rock formation under Earth’s outer layer. 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.

Giovanni and his family go on a trip and they drive over a mountain range. Giovanni wonders how the rock they see as they drive over the mountain range might be different when they drive back home next week. 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.

Answer explanation

The Grand Canyon that we see today took billions of years to form.

Africa and Europe are very close to each other, but they used to be far apart. Which diagram below 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.

Mining companies have technology that can detect rock formations underneath Earth’s outer layer. One mining company detects an igneous rock formation underneath Earth’s outer layer. The geologists working for the company wonder if material in this igneous rock used to be sedimentary rock at Earth’s surface. Can material in sedimentary rock become igneous rock? Explain your answer.

Answer explanation

The igneous rock formed from magma that cooled down. If sedimentary rock is subducted by plate motion into Earth’s interior and is exposed to energy from Earth’s interior and melts to form magma, then the igneous rock could have been sedimentary rock in the past.

Dr. Nomura is a geologist who studies rock formations from the Cretaceous period of Earth’s history. His most recent study compares rocks from rock formations in two different locations. The information from the study is as follows:

Rock A formed from small pieces of rock. Rock B formed from liquid rock in a different place. Rocks A and B formed at about the same time in the Cretaceous period.

Dr. Nomura wants to write a report to other geologists. Are Rocks A and B the same or different types of rock?

The rocks are

different types because they formed in different places.

different types because they formed in different ways.

the same type because they formed at the same time.

the same type because they both formed from rock material.

Astronomers studying the planet of Rhombus have detected sedimentary rock on its surface. One astronomer wonders if material in this sedimentary rock used to be in igneous rock deep in Rhombus’s interior. Can igneous rock become sedimentary rock? Explain your answer.

Evaluate responses using AI:

OFF

Answer explanation

The sedimentary rock formed from sediment that was compacted and cemented. If igneous rock is uplifted by plate motion toward Rhombus’s surface and is exposed to energy from Rhombus’s sun, so wind and water can move and weather the igneous rock into sediment, then the sedimentary rock could have been igneous rock in the past.
