DEFINITIONS:
1)__This is gathered from long term statistical averages of temperature, precipitation, etc.
2)__ This is the term which collectively describes the portions of the Earth’s surface where water is in solid form.
3)__This is a combination of sunlight, infrared, and ultraviolet radiation.
4)__In order to achieve this, heat flow in must be equal to heat flow out.
5) __These trap heat near the earth’s surface.
6)__These can provide a detailed record of earth’s climate.
7)__Long term climate changes are explained by these periodic variations in earth’s movement around the sun.
8)__The burning of these has released carbon-dioxide into the atmosphere during the 20th century.
9)__These are measured from oxygen isotope ratios.
Part b) What are the three periodic variations in the earth’s movement around the sun?
Part c) True or False:
Mark T (true) or F (false) in the blank provided:
1)__Plate tectonics are considered as a possible cause of past ice ages.
2)__Temperatures and greenhouse gas concentrations decline during ice ages.
3)__The earth is not in thermal equilibrium with the sun.
4)__Weather is gathered from long term statistical averages of temperature and precipitation.
5)__Solar heating drives most of earth’s various climate systems.
6)__All planets with carbon dioxide in their atmospheres will experience a greenhouse effect.
7)__During deglaciation (the melting of glaciers), temperatures and greenhouse gas concentrations rise.
8)__Albedo is solar radiation absorbed by the earth’s surface.
