 Earth’s atmosphere is: A blanket of air that surrounds and
protects the earth.
 The Layers of the Atmosphere:
1. Troposphere: The layer we live in, and where weather
occurs.
2. Stratosphere: The layer that protects the Earth from
harmful UV rays, and where the ozone
layer is located.
3. Mesosphere: The layer that protects the Earth from
meteors.
4. Thermosphere: The layer where satellites are located.
 Weather: What the air around us is like at certain period
in time.
- Example: Rain, snow, sleet, hail, sunshine
 Climate: The pattern of weather in a certain place over
a long period of time.
1. Air takes up space, and takes the shape of its
container.
2. Air has layers (the layers of the atmosphere)
3. Air pushes on things and has pressure.
4. The temperature of air can be measured.
 Air mass: A large body of air with the same temperature
and moisture.
 Front: When a two air masses meet, and a weather
change occurs.
1. Warm Front:
- When a warm air mass stretches over a cold air
mass.
- Light steady rain or snow occurs for longer periods
of time.
2. Cold Front:
- When a cold air mass pushes up and under a warm
air mass
- Heavy rain, thunderstorms, or snow occur for short
periods of time.

 Meteorologists use weather tools to: measure and
predict the weather to prepare citizens.
 Anemometer: Measures the speed of the wind.
 Hygrometer: Measures the amount of humidity in the air.
- Humidity: The amount of water vapor in the air.
 Rain Gauge: Measures the amount of rain that has
fallen.
 Thermometer: Measures the temperature of the air.
 Barometer: Measures air pressure.
 Weather Vane: Measures the direction the wind is
blowing.
