Part 1

Thin layer of earth with suitable conditions for life

The atmosphere, lithosphere, and hydrosphere, all living things

The layer of gases that surrounds the earth

Nitrogen, oxygen, and small amounts of other gases

Troposphere, Stratosphere, Mesosphere, Thermosphere

First 0-10km Contains 80% of atmospheric gas Temperature range from 15C to -60C Only part of atmosphere that can support life Where most weather occurs

10-50km Contains the ozone layer Temperature ranges from -60C to 0C

50-80km Temperature ranges from 0C to -100C

80-500km Contains very little gases Temperature ranges from -100C to 1500C

All the water on earth (solid,liquid,gas)

Solid portion of earth that sits above the earths mantle

• Composed of rocks, minerals, and elements • Extends up to 100km below the surface • Warmed by the sun and molten from earths mantle

Radiant energy transmitted as electromagnetic waves

The amount of solar energy received by a region on earths surface

Time of year, angle of inclination, length of daylight, clouds, atmospheric dust, and the albedo effect

The degree that the earths poles are tilted from the perpendicular plane of orbit.

The angle between a ray falling on a surface and the line perpendicular to that surface

Solar energy is spread out over a greater and the region receives less insolation

The percentage of solar radiation it reflects

30% or 0.30

Surface features

Low

Seasons

Clouds reflecting solar radiation resulting in cooler temperatures on cloudy days
