What is Weather?

© Erin Kathryn 2016

• Weather is the

conditions of Earth’s
atmosphere at a
certain time and place.

• For example, sunshine,

rain, hurricanes, and
storms are all
examples of weather.

• Weather is different

at different places
around the world.

Earth’s Atmosphere

© Erin Kathryn 2016

• The atmosphere is the

layers of air that surround
Earth’s surface.

• Earth’s atmosphere has 4

layers: troposphere,
stratosphere, mesosphere
and thermosphere.

• Weather occurs in the

first layer of the
atmosphere, the
troposphere.

Climate

• Climate is the usual weather conditions of a

place over an extended amount of time.

• Climate has a lot to do with the kinds of

plants and animals that can live and survive
there.

Climate

• How much sunlight an area gets, oceans

or large bodies of water, altitude, and
mountains are all factors that affect
climate.

• Scientists learn about climate by

looking at tree rings in old fossils and
evaluating core samples of ice to see
how the layers of fossil and ice have
changed over time.

What Causes Weather?

© Erin Kathryn 2016

• Weather conditions include temperature,

humidity, wind, and air pressure.

• Temperature – how hot or cold the air is
• Humidity – the amount of water vapor

in the air

• Wind – the movement of air
• Air pressure – the weight of air as it

presses down on Earth.

Air Masses

© Erin Kathryn 2016

• An air mass is a large body of air that

has about the same temperature, air
pressure, and moisture.

• Air masses are either warm or cold and

either moist or dry.

Air Masses

© Erin Kathryn 2016

• Warm air masses usually form near

warm places.

• Cold air masses usually form near cold

places.

• Moist air masses usually form over

oceans.

• Dry air masses usually form over land.
• Most changes in weather happen when

one air mass moves into a place and
pushes out another air mass.

Multiple Choice

An air mass is

• a large body of air with about the same temperature and humidity throughout

• the amount of moisture in the air

• a place where two different air masses meet

• a cold air mass that bumps against a warm air mass

Multiple Choice

If an air mass forms above land, it will be

• wet

• dry

• cold

• hot

Multiple Choice

If an air mass forms over an ocean it will be

• wet

• dry

• cold

• warm
