Answer 1

Earth

Question 2

It is made up of 70% water and 30% land.

Answer 2

Earth’s surface

Question 3

Identified according to their chemical components.

Answer 3

Compositional Layers

Question 4

Examples of Compositional Layers

Answer 4

Crust, Mantle, and Core

Question 5

Identified according to their physical properties.

Answer 5

Mechanical Layers

Question 6

Examples of Mechanical Layers

Answer 6

Lithosphere, Asthenosphere, Mesosphere, Outer core, and inner core

Question 7

The outermost and thinnest layer of the earth.

Answer 7

Crust

Question 8

This layer makes up 1% of Earth.

Answer 8

Crust

Question 9

Habitable and Widely studied layer
-Oceanic and Continental Crust

Answer 9

Crust

Question 10

The Thickest layer is semi-solid, rocky, and viscous.

Answer 10

Mantle

Question 11

900-3700 degree celcius

Answer 11

Mantle

Question 12

-Viscous because of temperature difference
-Made of hot and dense rock
-Convection cells

Answer 12

Mantle

Question 13

-Molten Nickle and Iron
-3700-4300 degree celcius
-Only the liquid layer

Answer 13

Outer core

Question 14

-Mostly Iron
-Has a high temperature and pressure
-Solid layer
-About 6000 degree

Answer 14

Inner core

Question 15

The cycle of heating, rising, cooling, and sinking.

Answer 15

Convection current

Question 16

-Made up of the crust and upper mantle.
-Divided into several parts called “tectonic plates”

Answer 16

Lithosphere

Question 17

Lies beneath the Lithosphere
Makes up the upper mantle
The pressure and temperature in this layer cause the deformation of rocks.

Answer 17

Asthenosphere

Question 18

Made up of the lower mantle
The flow of rocks in this layer is much slower.

Answer 18

Mesosphere

Question 19

Caused by the movements inside the earth.

Answer 19

Seismic waves

Question 20

The transition zone between the crust and mantle

Answer 20

Mohorovicic Discontinuity

Question 21

The transition zone between the mantle and core

Answer 21

Guttenberg

Question 22

The transition zone between the outer core and inner core

Answer 22

Lehmann

Question 23

Can travel through the earth’s inner layers

Answer 23

Body waves

Question 24

Can only travel through the planet’s surface like ripples in the water.

Answer 24

Surface waves

Question 25

0-70 km

Answer 25

Shallow Focus

Question 26

70-300 km

Answer 26

Intermediate Focus

Question 27

300 km- deeper

Answer 27

Deep Focus
