Answer 6

Divergenct boundary

Question 7

The supercontinent from where present continents came from is named?

Question 8

The San Andreas Fault is an example of this kind of fault, where nearly vertical fault planes slide in parallel but opposite directions.

Answer 8

Strike-slip up fault

Question 9

An area in the mantle from which heat from deep within the Earth rises as a thermal plume is known as

Answer 9

Magma

Question 10

Which theory considers the geographical features of the Earth’s surface as a result of the contraction and wrinkling of the planet as it cools down?

Answer 10

tectonic plate theory

Question 11

Which type of plate boundary produces a very strong earthquake?

Answer 11

Convergent boundary

Question 12

A process where two plates collide in which the denser plate goes beneath the less dense plate is called?

Answer 12

Subdunction

Question 13

The theory of tectonic plates was initiated by?

Answer 13

Alfred Wegener

Question 14

The process that produces new seafloors between two diverging plates is called?

Answer 14

Seafloor Spreading

Question 15

Who proposed and what year The continental drift theory was?

Answer 15

Alfred Wegener in 1912

Question 16

Is Pangea a Greek word that means?

Answer 16

“all the eart”

Question 17

Pangea broke into smaller continents called?

Answer 17

Laurasia and Gondwanaland

Question 18

What is the evidence for the continental drift theory(TCD)?

Answer 18

Fossils of living things. such as plants, rocks

Question 19

What are the two continents that fit the most noticeably?

Answer 19

South america and africa

Question 20

Originally the Continental drift theory was not well received by other scientists. Why?

Answer 20

There was no data showing the continents ever moved.

Question 21

A preserved remains or traces of organisms (plants and animals) from the remote past?

Answer 21

Fossils

Question 22

Who are the scientists proposed seafloor spreading and what year is it?

Answer 22

Harry Hess and Robert Dietz in 1960

Question 23

What are the findings that support seafloor spreading Theory

Answer 23

1. Rocks are younger at the mid-ocean ridge.
2. Rocks far from the mid-ocean ridge are
   older.
3. Sediments are thinner at the ridge.
4. Rocks at the ocean floor are younger than
   those at the continents.

Question 24

How TSFT contradicts parts of CDT?

Answer 24

Because the theory of CDT plates moves not because there is ocean, he said that it only moves because it’s sturdy , larger continents broke throufgt the oceanic. Whereas, the
seafloor spreading shows that the
ocean is the actual site of tectonic
activity.

Question 25

A vibration of the earth produced by the rapid release of energy most often because of slippage along a fault in the earth’s crust?

Answer 25

Earthquake

Question 26

This energy radiates in all directions from the focus in the form of waves called?

Answer 26

Seismic waves

Question 27

What are the two types of seismic waves?

Answer 27

Body waves and surface waves

Moves the ground in a side to side horizontal motion and names after A.E.H Love, a british matematician in 1911?

Answer 30

Love waves

Question 31

Roles alongs the ground just line a wave rolls across a lake or an ocean/ moves up and down or side to side?

Answer 31

Rayleigh waves

Question 32

Can travel through the Earth’s inner layers, used to study earth interior, have a higher frequency than the surface waves?
