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.
