Weather And Climate

Front 1

Compare weather and climate

Back 1

Weather is the daily atmospheric conditions, while climate is the average atmospheric conditions

Front 2

Name the layers of the atmosphere (starting closest to earth)

Back 2

Troposphere, stratosphere, mesosphere, thermosphere

Front 3

List a characteristic of the troposphere

Back 3

Contains all weather

Front 4

List a characteristic of the stratosphere

Back 4

Contians ozone layer

Front 5

List a characteristic of the mesosphere

Back 5

Meteors burn up there

Front 6

List characteristics of the thermosphere

Back 6

Contains auroras

Front 7

Where is the ozone layer, and why is it so important?

Back 7

The ozone layer is in the stratosphere, and it protects us from harmful UV radiation released from the sun

Front 8

How does temperature change as you go into the troposphere?

Back 8

The further up in the troposphere you are, the cooler the temperatures become

Front 9

What happens to air pressure as you go further into the atmosphere? Why?

Back 9

Air pressure decreases as air molecules spread out and it becomes less dense.

Front 10

What happens to air pressure as elevation increases?

Back 10

Air pressure decreases

Front 11

What happens to air pressure as water vapor decreases?

Back 11

Air pressure increases

Front 12

What happens to air pressure as temperature decreases?

Back 12

Air pressure increases

Front 13

What instrument do you use to measure air pressure?

Back 13

A barometer

Front 14

What part of the global wind system do we live in?

Back 14

The westerlies

Front 15

How does air pressure move (low-->high, high-->low, both)?

Back 15

High to low

Front 16

Process in which warm fluids rise and cool sink

Back 16

Convection

Front 17

What effect makes winds appear to curve due to earth's rotation?

Back 17

Coriolis force

Front 18

Would the air at the equator rise or sink?

Back 18

Rise

Front 19

The day time diagram shows __________, and the night time diagram shows_________.

Back 19

Daytime diagram-sea breeze

Night time diagram-land breeze

Front 20

Humidity

Back 20

The amount of moisture in the air

Front 21

Relative humidity

Back 21

Percentage of saturation in the air

Front 22

Absolute humidity

Back 22

Weight of water in a given volume of air

Front 23

Capacity

Back 23

Maximum weight of water vapor that a given volume of air can hold at a definite temperature

Front 24

Dew point

Back 24

Temperature at which the air much cool in order to be saturated

Front 25

Saturation

Back 25

Air that is filled to capacity with water vapor

Front 26

Condesation

Back 26

The change of water vapor into liquid water

Front 27

When air is cooled, it can hold ______ vapor than before

Back 27

Less

Front 28

Why does dew form on the grass in the morning?

Back 28

During the day, the air is warmer and can hold more moisture. At night, air cools and can't hold hold moisture so the water vapor condenses out of the air and onto surface in the form of dew.

Front 29

List the three steps of cloud formation

Back 29

1.) Sun's heat warms the ground

2.) Warm air forms above the ground and begins to rise

3.) As a warm air bubble rises, it cools it to its dew point temperature and condenses on particles in the air to form clouds

Front 30

What are the two most common gases in the atmosphere, and what are their percentages?

Back 30

Nitrogen (78%) and Oxygen (21%0

Front 31

Why do we have seasons?

Back 31

Earth's axis is tilted, resulting in unequal amounts of heat energy year round

Front 32

What are some greenhouse gases?

Back 32

Water vapor, carbon dioxide, methane, ozone

Front 33

What are some ways that carbon is put into the atmosphere?

Back 33

Humans, animals, industry, plants, oceans

Front 34

What is the largest source of pollution to our atmosphere?

Back 34

Burning fossil fuels

Front 35

What are some possible consequences of climate change?

Back 35

Melting glaciers, water shortages, wildfires, etc.

Front 36

Albedo

Back 36

The percentage of light reflected by an object

Front 37

How does elevation affect climate?

Back 37

As you go higher in elevation, the average temperature of region decreases

Front 38

How does latitude affect climate?

Back 38

As latitude increases (moving towards the poles), average temperatures decrease

Front 39

How does proximity to water bodies affect climate?

Back 39

Being located to a body of water moderates temperatures, keeping them fairly constant as well as increasing the amount of rainfall

Front 40

How do global winds affect the climate?

Back 40

Global wind belts carry heat around the globe as well as large amounts of water.

Front 41

How does topography and mountain ranges affect the climate?

Back 41

Mountain ranges affect the amount of rainfall in an area by forcing them upwards, creating a large amount of rainfall on one side of a mountain and none on the other.

Front 42

Greenhouse effect

Back 42

The natural warming of earth due to the trapping of heat by greenhouse gases

Front 43

How are winds named?

Back 43

By the direction in which they move

Front 44

Isobars

Back 44

Lines of equal air pressure
