Quiz #15 Lesson 2.1/3.1 U3RT Period 4/5/65

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.

A mining company was comparing rock samples from two different mines. Their observations showed that the rock samples were two different types of rock.

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 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.

Michelangelo's David is a statue that was carved in the early 1500s. The statue is made from marble, which is a type of metamorphic rock. How did the metamorphic rock used in the David form?

• It melted and cooled.

• It broke into sediment and then compacted.

• It was heated and put under pressure.

• Rock doesn’t form; it stays as it is.
