Unit 4 Review: Earth's Surface and Evidence of Plate Motion

Question 1

Ocean trenches are most often formed when _________________________.

Accepted Answer

an oceanic plate is forced underneath a continental plate.

Question 2

Select the boxes to identify which Earth layer each part of the model represents.

Accepted Answer

Cork=crust, Heat source=core, Water=Mantle

Question 3

How is new crust created at divergent plate boundaries?

Accepted Answer

Magma rises to the surface, cools, and hardens into igneous rock.

Question 4

Which of the following statements provides evidence of Pangaea?

Accepted Answer

Fossils of the same plants and animals can be found on different continents, Earth’s tectonic plates are still moving today, The shapes of Earth’s continents fit together like a puzzle

Question 5

Which statement best describes the ability of this model to predict plate movement?

Accepted Answer

The motion of the plates can be modeled because convection moves plates

Question 6

Which two statements are correct about the effects of these plate boundaries on Earth's lithosphere?

Accepted Answer

In Type 2 boundaries, one plate is forced under the other, forming a trench, Earthquakes tend to occur at both Type 2 and Type 3 boundaries

Question 7

Which statement is correct based on the information provided in the two diagrams?

Accepted Answer

The diagrams provide support for the theory that the continents have moved

Question 8

Based on the diagram and explanation below, what causes Earth's plates to move?

Accepted Answer

Heat from Earth's core causes the liquid magma to form convection currents.

Question 9

Which type of plate boundary forms new crust as plates move apart, causing magma to rise and cool into igneous rock?

Accepted Answer

Divergent boundary

Question 10

Though the two continents were once joined, __________caused movement of the continents to their current positions.

Accepted Answer

seafloor spreading by Earth's plates moving

Question 11

According to the data below, where do MOST earthquakes occur?

Accepted Answer

Plate boundaries

Question 12

The evidence supporting the claim that the continents were once joined includes the ____________________________.

Accepted Answer

presence of identical fossils on the coastlines of different continents

Question 13

Fossils of a now extinct dinosaur have been found near the east coast of South America and the west coast of Africa.

Accepted Answer

This evidence support that the continents were once connected.

Question 14

Which location on Africa would have once matched to Location R on South America before the landmass Pangaea broke apart?

Accepted Answer

Location 3

Question 15

Remains of Mesosaurus have been found in these locations. Which statement is the BEST conclusion from this evidence?

Accepted Answer

The continents of South America and Africa were once joined.

Question 16

The Appalachian Mountains are folded mountains that reach to about 3,000 feet high. How did these mountains form?

Accepted Answer

Folded mountains occur when two tectonic plates push against each other

Question 17

Seafloor spreading is one reason _________________________________.

Accepted Answer

the continents are drifting apart.

Question 18

Which of the following statements provides evidence of Pangaea? (choose 3)

Accepted Answer

Earth’s tectonic plates are still moving today, Fossils of the same plants and animals can be found on different continents, The shapes of Earth’s continents fit together like a puzzle

Question 19

What is the term for the process of the oceanic lithosphere sinking into the mantle, causing it to melt?

Accepted Answer

Subduction

Question 20

Why does Earth's crust stay the same size?

Accepted Answer

New crust forms at divergent boundaries, old is destroyed during subduction

Question 21

The evidence supporting the claim that the continents were once joined includes the _______________.

Accepted Answer

identical fossils line up on Africa's west coast and S. America's eastern.

Question 22

The movement shown in the map indicates that Africa’s continental crust is splitting apart. What will most likely happen

Accepted Answer

The Indian Ocean will flood the lowlands when the rift reaches the ocean.

Question 23

Which landforms are created at a divergent plate boundary as magma rises to the surface and cools?

Accepted Answer

mid ocean ridges

Question 24

Examine the diagram which shows a plate boundary between oceanic crust and continental crust. What feature will form?

Accepted Answer

volcanic arc

Question 25

The map below shows Earth's tectonic plates. The arrows represent how the plates are moving. What occurs at spot 1?

Accepted Answer

The plates are moving apart. Magma rises upward and forms a rift valley.

Question 26

According to the theory of continental drift,why do the coastlines of Africa & South America appear to fit together well

Accepted Answer

Africa & South America used to be joined together, but split apart long ago

Question 27

The highest mountains in the world are the Himalayas,at the border between the Indian and Eurasian plates.The Himalayas

Accepted Answer

Formed where two tectonic plates collided at a convergent boundary

Question 28

Which of the following features typically occur at transform plate boundaries?

Accepted Answer

Earthquakes

Question 29

Based on the diagram below, what causes ocean trenches to form?

Accepted Answer

Two plates collide at a convergent boundary,one slides underneath the other

Question 30

Which would provide evidence of seafloor spreading?

Accepted Answer

age of rocks closer to the divergent boundary are younger,older are further
