Mod 4 Lesson 3

Question 1

What is Convection?

Answer 1

movement caused by hotter, less dense material rising while cooler, denser material sinks

Question 2

What is a Hotspot?

Answer 2

where molten magma rises to just underneath the surface of Earth, creating a bulge or volcanic activity

Question 3

The material inside Earth’s mantle is always moving in a _______ motion.

Answer 3

circular

Question 4

When the tectonic plates push together, pull apart, or slide, they create energy that is released in the form of seismic waves. These waves create movement in the rocky portion, causing an _______.

Answer 4

earthquake

Question 5

Not all earthquakes and volcanoes happen at plate boundaries

True or False

Answer 5

True

Question 6

Volcanoes form at which two tectonic plate boundaries

Answer 6

Convergent and divergent boundaries

Question 7

Tectonic plates collide as they move toward each other. The rocky material is forced upward, creating _______ very slowly over geologic time.

Answer 7

mountain chains

Question 8

Ocean Basins form at which tectonic plate boundary

Answer 8

Divergent boundaries

Question 9

_______ occur when plates divide and pull away from each other and new crust is created like in seafloor spreading.

Answer 9

divergent boundaries

Question 10

______ boundaries occur when the crust is destroyed as one plate dives under another in a process known as subduction.

Answer 10

Convergent

Question 11

In ______ boundaries, crust is neither produced nor destroyed and the plates just slide horizontally past one another.

Answer 11

transform

Question 12

Mantle

Answer 12

Layer with partially melted material that moves the tectonic plates

Question 13

Convergent boundary

Answer 13

Tectonic plates that move toward each other

Question 14

Divergent boundary

Answer 14

Tectonic plates that move away from each other

Question 15

Transform boundary

Answer 15

Tectonic plates that slide past each other

Question 16

Convection

Answer 16

The type of heat transfer that causes the tectonic plates to move

Question 17

Volcano

Answer 17

Created when tectonic plates allow molten magma to escape and build up over time

Question 18

Mountain

Answer 18

Created when tectonic plates collide and uplift the rocky material above the surface of Earth

Question 19

Ocean basin

Answer 19

Created underwater when tectonic plates move apart and the space fills with new, hardened crust

Question 20

Earthquake

Answer 20

Occur when tectonic plates collide, pull apart, or slide past each other, creating a release of energy

Question 21

What type of boundaries for Earthquakes occur?

Answer 21

Convergent, divergent, and transform boundaries

Question 22

What type of boundaries for volcanoes occur?

Answer 22

Convergent and divergent boundaries

Question 23

What type of boundaries for Ocean basins occur?

Answer 23

Divergent boundaries

Question 24

What type of boundaries for Mountain Ranges occur?

Answer 24

Convergent boundaries

Question 25

How do Ocean Basins happen?

Answer 25

As tectonic plates move apart, molten magma may seep up through to the surface and harden. This new rocky land fills in the space left by the diverging plates.

Question 26

How do Mountain Rangeshappen?

Answer 26

Tectonic plates collide as they move toward each other. The rocky material is forced upward, creating mountain chains very slowly over geologic time.

Question 27

How do volcanoes happen?

Answer 27

When tectonic plates push together or pull apart, magma from within the Earth's mantle works its way to the surface, where it may erupt as lava. Over time, the build-up of hardened lava and ash causes a volcano to grow larger.

Question 28

How do earthquakes happen?

Answer 28

When the tectonic plates push together, pull apart, or slide, they create energy that is released in the form of seismic waves. These waves create movement in the rocky portion, causing an earthquake.
