ECB Unit #8 Types of Rock and Rock Cycle

Igneous rocks are classified by where they are formed. Which type of igneous rock forms

underground?

• Extrusive

• Intrusive

• Volcanic

• Ash

Extrusive rocks are formed by __________________.

• lava cooling on Earth's surface.

• pressure inside the Earth.

• magma cooling below Earth's surface.

• tidal deposits of sediment.

Which would NOT be listed as a necessary process for sedimentary rock formation?

• Melting

• Compaction

• Pressure

• Time

Granite is a rock that is formed from magma inside of a volcano. Which type of rock would granite

most likely be?

• Intrusive Igneous

• Sedimentary

• Foliated Metamorphic

• Extrusive Igneous

During the deposition phase of the formation of a sedimentary rock, the eroded material is

• dropped to the surface after being carried from one place to

  another.

• transported from one place on Earth’s surface to another.

• pressed together and begins to harden to become solid again.

• pressed and glued together over a long period of time.

According to the rock cycle, which of the following statements is true?

• Only sedimentary rock gets weathered and eroded.

• Sedimentary rocks are made from metamorphic, igneous, and sedimentary rock fragments and

  minerals.

• Heat and pressure create igneous rocks.

• Metamorphic rocks are created by melting and cooling.

find?

• Igneous

• Metamorphic

When magma reaches Earth's surface it becomes

• gas.

• steam

• energy

• lava

Sedimentary rocks can be converted into magma by undergoing which of the following processes?

• Weathering and erosion.

• Cooling and crystallization.

• Heat and pressure.

• Compaction and cementation.

Where do sediments come from?

• There have always been sediments on Earth

• Sediments accumulated as dust fell to Earth from other space

• Weathering of other rocks

• Coarse-grained rocks
