Unit 3 Lesson 2 Quiz Review

What process must occur first for a metamorphic rock to begin its transformation into a sedimentary rock?

• A layer of soil must accumulate over the rock.

• The rock must undergo melting and solidification.

• Weathering and erosion must break down and transport the rock material.

• Decomposition of organic matter must take place on the rock surface.

Diorite is a rock that forms when magma cools slowly beneath the Earth’s surface. Rhyolite is a rock that forms from lava cooling quickly on the Earth’s surface. What do these rocks have in common?

• They are both kinds of igneous rock.

• They are not made up of minerals.

• They are the same exact color and texture.

• They are made up of layers of sediment.

Around 4.5 billion years ago, scientists think a planet-sized object hit Earth, sending material into space that eventually formed the Moon we see today. Which 2 rock cycle processes are represented in this artist's depiction of the event?

• weathering

• erosion

• vaporization

• solidification

Bennetha collected samples of a sedimentary rock. Which 2 statements are true about how sedimentary rocks form?

• The rock formed as magma or lava cooled.

• Water and wind likely played a significant role in the formation of the rock.

• This rock was changed from a different type of rock by heat and pressure.

• Energy from the sun was the source of energy that resulted in the formation of this rock.

In a galaxy far far away on the planet Glorb, students are debating about the factors associated with how igneous rocks form. Jayden and Lydia argue that heat from Earth’s interior is involved, while Delilah and Natasha argue that only pressure is involved. Skibidi Master Baby Gronk and Kiana are also in the corner of the room chanting "they're coming" for some reason...super weird.

Who is right? And do Skibidi Master Baby Gronk and Kiana need mental help?

• Jayden and Lydia, yes they do... very badly

• Delilah and Natasha, yes they do... very badly

Which factors are associated with the formation of metamorphic rock?

• intense heat and pressure

• sun and water

• weathered rock

• existing solid rock

Which factors are associated with the formation of sedimentary rock?

• intense heat and pressure

• weathered rock

• existing solid rock

• magma cooling

Sandstone is a rock that forms when sediment such as sand and other minerals are compacted and cemented together. Where did the energy come from that resulted in the formation of the sediment that makes up sandstone?

• solar

• chemical

• geothermal

• heat and pressure

Explain the difference between the way intrusive igneous rock forms and the way extrusive igneous rock forms.

• Intrusive forms inside Earth, extrusive forms on the surface

• Intrusive forms on the surface, extrusive forms inside Earth

• Both form inside Earth

• Both form on the surface

What role does water play in the rock cycle?

• It only transports sediment.

• It acts solely as an agent of chemical weathering.

• It plays no role in the rock cycle.

• It participates in weathering, erosion, and the transportation of sediment.
