Tectonic Plates

Question 1

Name the layers of the structure of the earth based on chemical properties:

Answer 1

Crust,
Mantle,
Core

Question 2

Name the layers of the structure of the earth based on physical properties:

Answer 2

Lithosphere
Asthenosphere
Mesosphere
Outer Core
Inner Core

Question 3

Crust:

Answer 3

-Earth’s most outermost layer.
-Solid
-Where the species known as humanity lives along with other species of organisms

Question 4

Mantle:

Answer 4

-Semi-solid
-Magma
-Thickest Layer in the Earth

Question 5

Core:

Answer 5

-Earth’s most innermost layer
-Contains Iron and Nickel

Question 6

Lithosphere:

Answer 6

-Solid
-Includes both crust and mantle in terms of chemical properties

Question 7

Asthenosphere

Answer 7

-Solid; but malleable, like clay.

Question 8

Mesosphere

Answer 8

Solid

Question 9

Outer Core

Answer 9

Liquid

Question 10

Inner Core

Answer 10

-Solid
-Highest Temperature

Question 11

What’s the difference between the Lithosphere and the Asthenosphere?

Answer 11

The Lithosphere is solid, hard, and the layer that we live on; however, the Asthenosphere is soft, semi-solid, and is the layer that is under the Lithosphere.

Question 12

What are the two types of crust?

Answer 12

Oceanic and Continental Crust

Question 13

Which type of crust is older?

Answer 13

Continental Crust is older than Oceanic Crust.

Question 14

Difference between Oceanic Crust and Continental Crust?

Answer 14

Oceanic Crust is thinner, but more dense and made primarily of basalt.

Continental Crust is thicker, but lighter and composed primarily of granite.

As the oceanic crust is more dense than the continental crust, the oceanic crust sinks under continental crust when they move towards each other.

Question 15

What are tectonic plates?

Answer 15

The earth’s lithosphere is broken into pieces called tectonic plates.

Question 16

What are the three different types of plates?

Answer 16

Primary plates;
Secondary plates;
Tertiary plates.

Question 17

What are the edges of tectonic plates called?

Answer 17

Plate boundaries.

Question 18

Name the 8 primary plates:

Answer 18

Cocos Plate;
Nazca Plate;
Caribbean Plate;
Arabian Plate;
Scotia Plate.

Question 20

Name three minor plates:

Answer 20

Caroline Plate;
