Earth Science Part 2

Front 1

The process whereby dense material sinks and low-density material rises to form a layered planet is called what?

Back 1

differentiation

Front 2

Suppose an ice-covered region like Greenland were moved by plate tectonics so that in ten million years, it would be located at the equator. Which of the following would be probable changes to its climate? Choose the best answer.

Back 2

The average temperatures would increase.

Front 3

Suppose that an ice-covered region like Greenland were moved by plate tectonics so that in ten million years, it would be found at the equator. Which of the following would be probable changes to its biology?

Back 3

The diversity of animal life would increase.
The diversity and extent of plants would increase.
The diversity and extent of polar animals would decrease.

Front 4

What is the plate boundary at which one plate is pushed beneath another called?

Back 4

a subduction boundary

Front 5

Where are volcanoes most often found?

Back 5

at plate boundaries

Front 6

What two processes are the major sources of the earth’s interior heat, which is the energy source for earthquakes, volcanic eruptions, and plate tectonic motion?

Back 6

residual heat form earth’s formation and radioactive decay

Front 7

Earth’s interior heat is the engine that powers which of the following?

Back 7

earthquakes
movement of the plates of the crust
volcanoes

Front 8

When plate motion pushes up a mountain range, which of the following statements would be false?

Back 8

There would be a decrease in the types of habitats found on the continent.

Front 9

Major earthquake activity is restricted to convergent boundaries

Back 9

false

Front 10

At which type of boundary is volcanic activity more violent than at other boundaries?

Back 10

convergent boundaries

Front 11

Where is the Ring of Fire, an area where lots of volcanoes and earthquakes occur, found?

Back 11

around the edges of the Pacific Plate

Front 12

Mountain ranges are most likely the result of what?

Back 12

a collision between two plates

Front 13

Scientists think that the convection currents, which may be responsible for the movement of plates, circulate through the what?

Back 13

asthenosphere/mantle

Front 14

What does the collision of one plate with another form?

Back 14

a convergent boundary

Front 15

Earthquake data is not useful for mapping divergent plate boundaries.

Back 15

false

Front 16

What is the boundary called that is formed by two plates sliding past each other?

Back 16

a transform fault

Front 17

What does the earth’s interior heat originate from?

Back 17

the decay of radioactive materials,
the residual heat from the formation of the earth

Front 18

If the earth’s interior were to suddenly cool, what would happen to plate tectonic motion?

Back 18

It would eventually stop.

Front 19

Ocean ridges are formed at what kind of boundary?

Back 19

divergent

Front 20

The motion of the earth’s plates creates all of the following except for which?

Back 20

convection currents in the outer core

Front 21

Transform fault and divergent boundaries generally have less violent quakes than convergent boundaries.

Back 21

true

Front 22

Heat from the interior of the earth is an energy source for plate motion.

Back 22

true
