Atmosphere
Layer of gases that surround the planet.
Thermosphere
90 km high; 1st layer exposed to radiation; thin air; temperature depends on solar activity.
Weather
Condition of the atmosphere at a certain place & time
Meteorology
Scientific study of the weather.
Altitude
Height in the sky.
Stratosphere
50 km; Ozone is included; warm.
Climate
The average weather in a more general location, usually compiled as an average from many decades.
Ozone
3 Oxygen molecules instead of 2; absorbs UV rays and heat.
Exosphere
Outermost layer; 640 kn; atmosphere pressure is low.
Water Vapor
H2O; allows the water cycle to process.
What is the difference between weather and climate?
Weather is at a certain point in time, while climate is the average over time.
Example of Weather
It was raining in Barnegat today.
Example of Climate
It is mostly sunny during July in the south.
Hydrosphere
Water on earth; 71% of the surface.
Geosphere
Largest sphere; layer of rock and earth beneath the ocean.
Atmosphere
Thinnest; layer of gases around Earth.
Biosphere
Life concentrated on the surface.
What gases make up most of the atmosphere?
Nitrogen, Oxygen, Argon, and others.
What is the percentage breakdown for gases in the air?
78% Nitrogen; 21% Oxygen; 1% Argon and other gases.
What 3 gases other than the primary ones found in air are critical to all life on earth?
Water Vapor, Ozone, and Carbon Dioxide.
How are the layers in the atmosphere different from one another?
They differ in temperature and composition.
What happens to the temperature in the Troposphere?
Decreases with altitude.
What happens to the temperature in the Stratosphere?
Increases with altitude.
What happens to the temperature in the Mesosphere?
Decreases with altitude.
What happens to the temperature in the Thermosphere?
Increases with altitude.
