Front 1

global warming

Back 1

a gradual increase in the temperature of earths atmosphere

Front 2

greenhouse gases

Back 2

gases in the atmosphere, such as carbon dioxide, that trap solar energy

Front 3

greenhouse effect

Back 3

the process by which heat is trapped in the atmosphere by water vapor, carbon dioxide, methane, and other gases

Front 4

crust

Back 4

the layer of rock that forms earths outer surface

Front 5

mantle

Back 5

the layer of hot solid material between earth's crust and core

Front 6

outer core

Back 6

a layer of molten iron and nickel that surrounds the inner core of the earth (liquid)

Front 7

inner core

Back 7

a dense sphere of solid iron and nickel at the center of the earth.

Front 8

lithosphere

Back 8

a rigid layer made up of the upper most part of the mantle

Front 9

asthenosphere

Back 9

the soft layer of the mantle on which the lithosphere floats

Back 11

a usually light colored igneous rock that is found in continental rock

Front 12

basalt

Back 12

a dark dense ingenious rock with a fine texture found in oceanic crust

what has risen about .5 degrees in the last 120 years

Back 13

the troposphere

Front 14

methane water vapor and carbon dioxide are all what?

Back 14

greenhouse gases

Front 15

what is the outcome of burning wood, oil, coal, and natural gases?

Back 15

more carbon dioxide is added to the air

Front 16

How might changes in solar energy affect Earth's climate

Back 16

there will be periods of warmer and cooler climate

Front 17

what is a possible affect of global warming
a) sea levels will drop
b)low lying coastal areas might be flooded
c) places too cold for farming today could become farmland
d) fertile fields might become dustbowls

Back 17

c, b, d
