Earth

Question 0

Inner Core and Outer Core

Answer 0

What are the two parts of the core called?

Question 1

Crust, Mantle and Core

Answer 1

What are the three MAJOR layers of the earth?

Question 2

Iron and Nickel

Answer 2

What elements make up the composition of the Core?

Question 3

Even though both layers are extremely hot (and the core is the very hottest) the massive amounts of pressure on the inner core makes it solidify

Answer 3

Why is the earth’s inner core solid but outer core liquid?

Question 4

It Increases

Answer 4

What happens to pressure as you go from crust towards the core?

Question 5

It Decreases

Answer 5

What happens to temperature as you go from the core to the crust?

Question 6

Density

Answer 6

What determines the separation of earth’s layers?

Question 7

How much mass there is in any given volume

Answer 7

What is density?

Question 8

The amount of space something takes up

Answer 8

What is volume?

Question 9

The core

Answer 9

Which of earth’s layers is the hottest?

Question 10

Crust

Answer 10

Which of earth’s layers is the coolest?

Question 11

Solid

Answer 11

What state of matter is the earth’s inner core in?

Question 12

Core, Mantle, Crust

Answer 12

List the layers from least dense to most dense

Question 13

inner core, outer core, mantle, crust

Answer 13

List the layers from hottest to coolest

Question 14

mantle, outer core, inner core, crust

Answer 14

List the layers from thickest to thinnest

Question 15

The crust and the upper-most mantle

Answer 15

Where is the lithosphere?

Question 16

continental and oceanic

Answer 16

What are the two types of crust?

Question 17

Because as you go closer to the core the layers get hotter and hotter. The mantle is sort of melted because of this intense heat.

Answer 17

Why is the crust of the earth solid but the mantle is partially solid and partially liquid?

Question 18

solid

Answer 18

What state of matter is the mantle?

Question 19

liquid

Answer 19

What state of matter is the outer core?

Question 20

warmer substance to a cooler substance

Answer 20

In terms of temperature, which direction does heat travel?

Question 21

Uranium

Answer 21

Which major element releases large amount of radiation in the Earth?

Question 22

radiation

Answer 22

Which form of heat transfer is used as uranium (nuclear energy) is transformed into geothermal energy to heat the inside of the earth?

Question 23

greenhouse effect

Answer 23

Radiant energy is used to heat the surface of the earth by transforming the light into heat as it travels through the atmosphere. His is called what kind of effect?

Question 24

water, magma, air

Answer 24

List 3 type of “fluids” on Earth that convection occurs in.

Question 25

rock samples

Answer 25

What is an example of direct evidence that supports the idea that the earth has layers?

Question 26

Answer 27

What is the highest point of a wave called?

Question 28

trough

Answer 28

What is the lowest point of a wave called?

Question 29

mantle and core

Answer 29

Where is the heat located that drives convection currents?
