This geological feature is formed when two continental plates collide.

What are mountains?

100

This layer in a typical soil profile is the topmost one.

What is the O horizon?

100

This characteristic of the earth is what largely determines the difference in seasons between the northern and southern hemispheres. 

What is the axis/tilted axis?

100

This major convection cell takes warm, humid air away from the equator and drops hot, dry air north or south of the equator. 

What is the Hadley cell?

100

This is the ocean in which El Nino events occur.

What is the Pacific ocean?

200

This process occurs when oceanic crust is forced under continental crust.

What is subduction?

200

This type of soil is generally best for growing plants as it doesn't allow water and nutrients to pass through too fast, but also doesn't waterlog plant roots. This is because it mixes all three particle types about equally.

What is loam?

200

This gaseous layer absorbs harmful UV radiation and prevents it from reaching the surface of the earth.

What is the ozone layer?

200

This occurs when an area of high elevation prevents precipitation from reaching another location.

What is a rain shadow?

200

This phenomenon explains why hurricanes spin counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.

What is the Coriolis effect.

300

Each magnitude up the Richter scale means that an Earthquake has increased in severity by this many times.

10 times

300

This type of soil particle, the smallest of the three, holds nutrients well, but is too tightly packed to allow water to reach plant roots reliably. 

What is clay?

300

This location on earth typically receives the most intense solar radiation year round.

What is the equator?

300

Close proximity to this geological feature allows coastal areas to maintain stable temperatures after the sun sets.

What is the ocean/bodies of water?

300

This is what happens to the trade winds during an El Nino event.

What is weakening/reversal?

400

This area in the world is know for the numerous earthquakes, volcanoes, and tsunamis due to high tectonic plate activity.

What is the Pacific Ring of Fire?

400

This metric for soil is important to understand the soils acidity, as most plants prefer soil to be slightly basic.

What is base saturation? 

400

This is the measurement for the amount of light that is reflected from the Earth's surface. It's percentage depends on the surface.

What is Albedo?

400

These are the rotating currents of surface water in the ocean. They move clockwise in the north and counter-clockwise in the south.

What are gyres?

400

This is the event that takes place after an El Nino, in which trades winds are more powerful than normal.

What is La Nina?

500

This occurs when magma breaks through a tectonic plate not near a plate boundary.

What is a hot spot?

500

This is the process that occurs in the E layer, in which nutrients or other dissolved substances are carried downward by water. 

What is leaching/eluviation?

500
List the following atmospheric levels in order: Troposphere - Exosphere - Mesosphere - Stratosphere - Thermosphere

What is Tropo - Strato - Meso -Thermo - Exo?

500

This is the process in which cold, nutrient rich ocean water is pulled to the surface as a result of currents. It usually occurs along coastlines.

What is Upwelling?

500

This is what ENSO stands for.

What is the El Nino Southern Oscillation?
