Video Lesson Goals:

Describe the primary components of the Earth

system: the atmosphere, hydrosphere, biosphere,

and geosphere.

Explain how three primary factors each influence

energy flow in Earths climate system: solar energy,

reflectivity, and the greenhouse effect.

Get out a piece of blank paper, or open

a blank electronic file in which you can

draw and write text.

Set a timer for 15 minutes.

Take 15 minutes to draw and annotate

what the phrase Earths Climate

System makes you think of.

Whats YOUR mental model?

The atmosphere, hydrosphere,

biosphere, and geosphere comprisea useful way to describe the basic

reservoirs for materials on Earth

Materials constantly exchange

among these reservoirs

The primary source of energy for

Earths climate system is the Sun

Key Points

The reflection characteristics of E

in all four reservoirs influences hoenergy reflects directly back to ou

Greenhouse gases in the atmosph

concentrations controlled by flow

to and from the atmosphere and t

reservoirs, act to slow the passage

from Earths surface back to space
