Plate Tectonics

Question 1

crust that is more dense

Answer 1

Oceanic crust

Question 2

It is a solid and rigid surface of the earth.

Answer 2

Lithosphere

Question 3

Crust that is less dense.

Answer 3

Continental crust.

Question 4

Give the parts of the lithosphere.

Answer 4

Crust and upper mantle.

Question 5

It facilitates the movement of the lithospheric plates.

Answer 5

Asthenosphere

Question 6

Makes up 68 percent of earth’s mass and 80 percent of earth’s total volume.

Answer 6

Mantle

Question 7

True or False.

Primary and Secondary waves cannot pass through liquid.

Answer 7

True

Question 8

Broken independent segments that move very slow.

Answer 8

Plate tectonics

Question 9

It is the fastest body wave. This wave can travel through both solid and liquid, and is also called pressure waves.

Answer 9

P waves or Primary waves

Question 10

This wave travels slower than the other type of wave. It has an up and down motion, and has a larger shadow zone because it can only travel through solids.

Answer 10

S waves or Secondary wavs

Question 11

It is the source of information resulting the current representation of the earth’s image.

Answer 11

Body waves.

Question 12

It is a type of Surface wave that is the fastest and moves side to side.

Answer 12

Love wave

Question 13

This wave has a circular motion at the bottom, and also has side by side waves.

Answer 13

Rayleigh waves
