Multiple Choice

What is a Pattern?

• Something we observe to be similar over and over again

• The place where two plates meet

• An object or diagram that helps us understand something

• Plate Boundary

• Mid-Ocean Ridge

• Trench

• Cross-Section

Multiple Choice

Hot liquid rock below the surface of Earth

• Lava

• Magma

Multiple Choice

Hot liquid rock on the surface of Earth

• Lava

• Magma

Multiple Choice

Cross Section

• A diagram that shows what the inside of something looks like.

• A diagonal portion of a larger object.

• When two line are drawn over each other at a 90⁰ angle.

• A piece of a pizza.

Multiple Choice

Mid-Ocean Ridge?

Multiple Choice

Where will geologists be able to find hard, solid rock?

• Neither under 1 nor 2, because there is sand and gravel under both places.

• Neither under 1 nor 2, because there is water under both places.

• Under 1 and 2, because Earth's entire outer layer is made of hard, solid rock.

• Only under 1, because Earth's outer layer is made of hard, solid rock under continents but not under the ocean.

Multiple Choice

Do the plates move quickly or slowly?

• Quickly

• Slowly

Multiple Choice

At this boundary, what will happen to locations A and B over time?

• A and B move away from each other over time.

• A and B will stay in the same area over time.

• A and B will move towards each other over time.

Multiple Choice

Outer Layer

• Crust

• Mantle

• Outer Core

• Inner Core

Multiple Choice

At this boundary, what will happen to locations A and B over time?

• A and B move away from each other over time.

• A and B will stay in the same area over time.

• A and B will move towards each other over time.

Multiple Choice

The plate boundary shown is ______________ . This means that _____ .

• Divergent; one plate will be pushed into the mantle and the other will experience uplift.

• Divergent; the plates will separate, and magma from the mantle will create new rock on the edges of the plates over time.

• Convergent; the plates will collide, and one plate will subduct into the mantle.

• Convergent; the plates will separate and water will fill the gap between them over time.

Multiple Choice

The plate boundary shown in the image is a ______ boundary because...

• Convergent; the plates are moving away from each other.

• Convergent; the plates are moving towards each other.

• Divergent; the plates are moving towards each other.

• Divergent; the plates are moving away from each other.

Multiple Choice

Can you feel the plates moving?

• Yes

• No

Multiple Choice

Which diagram shows what happens at a convergent plate boundary?

• A

• B

• A and B

• None of the above

Multiple Choice

Earthquakes are caused by plate motion. The plates are constantly moving, and this sometimes causes sudden shaking at the surface.

• True

• False

Multiple Choice

Which sentence about earth's outer layer is true?

• When the plates of the outer layer move, there are places were the mantle is exposed to the air and water at the surface.

• Although the plates of the outer layer move, the mantle is always above the outer layer and is closer to the air and water at the surface.

• The outer layer is always made up of hard solid rock. The mantle is always below the outer layer, and is not exposed to the surface.

• The outer layer is sometimes made of hard solid rock, and sometimes made of soft solid rock. It depends on how much magma is rising up from the mantle.

Multiple Choice

Geologists look for _____ in geologic events and landforms to better understand Earth's outer layer.

• Solutions

• Unexpected changes

• Patterns

• Fossils

Multiple Choice

What best describes Earth's mantle?

• Liquid, melted rock below the outer layer.

• The hard, solid rock beneath the plates.

• Liquid, melted rock on which the plates move.

• The soft, solid rock on which the plates move.

Multiple Choice

Plate motion is caused by earthquakes that push the plates around.

• True

• False

Multiple Choice

An earthquake is…

• the slow plate motion that is constantly happening to the plates.

• the sudden shaking of Earth's surface.

• the reason that plates have any motion.

• a mild geologic hazard.

Multiple Choice

What is a plate boundary?

• The single point where Earth's plates have motion.

• The place along which two plates meet.

• Long lines on the ground that cause the plates to move.

• The only location on Earth where earthquakes are possible.

Multiple Choice

The pieces that make up Earth's surface are called…?

• Jigsaw puzzle

• Pattern
