Ch.3 Study Guide

Front 1

The thin layer of Earth's surface where life exists is called the______.

Back 1

Biosphere

Front 2

The thin layer of the Earth upon which tectonic plates move around is called the______.

Back 2

Asthenosphere

Front 3

78% of Earth's atmosphere is made up of______.

Back 3

Nitrogen

Front 4

The ozone layer is located in the_______.

Back 4

Stratosphere

Front 5

Convection is defined as the______.

Back 5

Transfer of heat by currents

Front 6

What is not a greenhouse gas?

Back 6

Nitrogen

Front 7

Liquid water turns into gaseous water vapor in a process called_______.

Back 7

Evaporation

Front 8

Currents at the surface of the ocean are moved mostly by______?

Back 8

Wind

Front 9

Which of the following statements about the biosphere is not true?

Back 9

Matter is constantly added to the biosphere

Front 10

Why does land that is near the ocean change temperature less rapidly than land that is located farther inland?

Back 10

The ocean absorbs over half of the solar radiation, it absorbs and releases heat more slowly than land. The temperature in the atmosphere changes slower too, than further inland does.

Front 11

__% if the air we breathe is made up of nitrogen.

Back 11

78%

Front 12

__% of the air we breathe is made up of oxygen.

Back 12

21%

Front 13

The atmosphere divided into 4 layers. What are they?

Back 13

Troposphere, Stratosphere, Mesosphere, Thermosphere

Front 14

_____ moves the energy through space in waves from the sun to heat the Earth's surface.

Back 14

Radiation

Front 15

_____ is the flow of heat from a warmer object to a colder one.

Back 15

Conduction

Front 16

_____ is the transfer of heat by air currents.

Back 16

Convection

Front 17

How does solar energy reach the Earth?

Back 17

Solar energy reaches the Earth as electromagnetic radiation, which includes visible light, infrared radiation, and ultraviolet light.

Front 18

Explain what causes Earth's weather.

Back 18

The troposphere is the layer of the atmosphere where weather occurs. It's Earth's densest atmosphere, the temperature decreases as altitudes increase in the troposphere.
