Geography 2

Front 1

Plate Tectonics

Back 1

Geophysical theory that postulates that Earth is made up of a large # of geological plates that move slowly across its surface.

Front 2

Converging

Back 2

2 plates are being forces 2gether by convection cells deep within the Earth.

ex. vocanic Cascade Range, Sierra Nevada,
Andes Mts.

Front 3

Diverging

Back 3

Tectonic plates moving away from each other. While diverging magma often flows from the earth's interior, creating mtn. ranges with active volcanoes.

ex. Iceland, Olduvai Gorge (African Rift)

Front 4

Transform Boundaries

Back 4

Locations where 2 plates slide past one another.

Front 5

Latitude

Back 5

Highest amount of insolation (Solar Energy) is received in the eauatorial region, which is the area between the equator and 23.5 degrees nor and south latitude.

Front 6

Land

Back 6

Heat and cool faster than bodies of water. Hot summers and cold winters are always found away from the coast. Continentality

Front 7

Water

Back 7

Retain solar heat longer than land areas,oceanic or maritime climates usually have moderate temperatures without the seasonal extremes found inland. Maritime climates.

Front 8

Atmospheric Pressure

Back 8

Driving the worlds wind and storm systems is t he uneven heating of Earth due to latitudinal differences and the arrangement of oceans and continents produces a regular pattern of high- and low-pressure systems in the North Pacific.

Front 9

Winds

Back 9

Air flows from high pressure to low. (Pressure System produces this) Thus, Winds flow away from high-pressure and into low-pressure cells.

Global Warming Major Gasses

Back 14

1. Co2 - more than 1/2 of human-generated greenhouse gases. ( Burning fossil fuels like coal and petroleum).

2. CFCs - Chlorofluorocarbons - 25 % of the human-generated greenhouse gases (aerosol sprays and refrigeration, including A/C)

3. CH4-Methane- 15% of anthropogenic greenhouse gases.

4. N2O - 5% of human-caused greenhouse gases from chemical fertilizers.

Earth Summits ( 1992,1997)

Back 15

1992 - 1st international agreement on global warming at Rio de Janiero Earth summit.

Signatories were bound by international law to reduce their greenhouse gas emissions by agreed-upon target dates.

1997 - Another attempt to develop an international treaty in Kyoto, Japanr-current vehicle for international action on climate change - The Kyoto Protocol. This actually increased global warming. Emitted 55% of the world's greenhouse gases.
