Question

1. Dr. Bayul studies rock formations all over the world. She is working on a study of two rock formations. The information from the study is as follows:

Rock A formed from liquid rock.Rock B formed from small pieces of 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

1 point
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.
2. Stonemasons work with rock, cutting it into shapes to use for building. One stonemason was unloading a new delivery of rocks and noticed that the delivery contained two different types of rock.

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

1 point
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 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 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.
3. Sandra takes a class field trip to a geology museum. She sees an interesting sample of igneous rock. She wonders if the material in this rock sample could have come from a sedimentary rock formation at Earth’s surface millions of years ago. Is this possible? Can sedimentary rock change into igneous rock?

1 point
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 forms under Earth’s outer layer due to energy from Earth’s interior, but sedimentary rock is only at Earth’s surface.
No, igneous rock can only form out of other igneous rock. Sedimentary rock cannot change into igneous rock.
4. Dr. Laszlo and his colleague Dr. Obasi are studying two different rock samples of different types of rock. How could energy have played a role in the different rock types forming?

1 point
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.
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 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.
5. On a geology field trip, Toccara’s class studies a sedimentary rock formation. Is it possible that material from this sedimentary rock could ever form igneous rock?

1 point
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.
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 forms under Earth’s outer layer due to energy from Earth’s interior, but sedimentary rock is only at Earth’s surface.
No, igneous rock can only form out of other igneous rocks. Sedimentary rock cannot change into igneous rock.

Answer 1

1. different types because they formed in different ways.

2. 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.

3. 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.

4. 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.

5. 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.
