The theory explaining the movement of the Earth's rigid lithospheric plates as a result of convection processes in the molten mantle underneath

What is plate tectonics?

100

When lithospheric plates pull apart from each other

What are divergent plate boundaries?

100

The primary use of freshwater globally

What is agriculture?

100

The primary reason that wind patterns in the northern hemisphere differ from those in the southern hemisphere?

What is the Coriolis effect?

100

The three aspects of soil found on a soil triangle

What are sand, silt, and clay?

200

When lithospheric plates come together.

What are convergent plate boundaries?

200

When lithospheric plates slide past each other

What are transform plate boundaries?

200

Porous layers of sand, gravel, or rock lying below the water table

What are aquifers?

200

The layer of the atmosphhere closest to earth where temperature drops as altitude increases, weather forms, and has the highest density of all layers

What is the troposphere?

200

How soil horizons are primarily categorized.

What are composition and organic content?

300

Features such as mountains, island arcs, earthquakes, and volcanoes are the results

What are the results of convergent plate boundaries?

300

This boundary is most often associated with earthquakes as its primary result

What are Transform boundaries?

300

A drier area of land next to a higher elevation, which blocks the precipitation from reaching this area

What is a rain shadow?

300

The layers of the atmosphere that occur at the greatest altitudes, not including the exosphere

What are the Mesosphere and Thermosphere?

300

The O horizon, plant litter layer, the upper part which typically experiences low decomposition but possibly contains high levels of humidity

What is the organic surface layer?

400

Features such as seafloor spreading, rift valleys, earthquakes, and volcanoes are the results

What are the results of divergent plate boundaries?

400

Major areas where divergent boundaries may occur (2 possible global regions)

What are the mid-atlantic (seafloor spreading) and east Africa (rift valley)?

400

A periodic, non-anthropogenic event that occurs in the south pacific which changes patterns of rainfall, wind, and ocean circulation.  Significant climate, environmental, and economic disruptions can result

What is the El Nino Southern Oscillation (ENSO)?

400

The layer in the stratosphere above which temperature increases

What is the ozone layer?

400

The A horizon, a layer of mineral soil with most organic matter accumulation and soil life. Additionally, due to weathering, oxides (mainly iron oxides) and clay minerals are formed and accumulated. It has a pronounced soil structure. But in some soils, clay minerals, iron, aluminum, organic compounds, and other constituents are soluble and move downwards.

What is surface soil?

500

Major areas where convergent boundaries may occur (3 possible global regions)

What is off the coast of northwestern north america, western south america, and east asia?

500

Major areas where transform boundaries result in frequent earthquakes (2 answers, you need both)

What are California (San Andreas fault) and India (the Himalayas)

500

Also known as drainage basins, these areas drain all streams and precipitation in an area to a common outlet

What is a watershed?

500

The term for the cycle where warm air rises and the equator, moves to roughly 30 degrees north or south latitude, and falls as cooler air.  The resulting precipitation between these latitudes helps create the tropical rainforest biome, and desert biomes around 30 degrees latitudes

What is a Hadley cell?

(Ferrell cells occur in mid-latitudes and polar cells around the poles)

500

This C horizon is below the solum horizons. This layer is little affected by pedogenesis. Clay illuviation, if present, is not significant. The absence of solum-type development (pedogenesis) is one of the defining attributes. The C horizon forms either in deposits (e.g., loess, flood deposits, landslides) or it formed from weathering of residual bedrock.
