Climates and Climate Change
100

This refers to a group of similar organisms that can breed and produce fertile offspring.

What is a species?

100

This location receives the most direct sunlight year round.

What is the equator?

100

These create currents along the surface of the ocean.

What are the prevailing winds?

100

This refers to all the gases that surround the earth.

What is the atmosphere?

100

Climate refers to the long-term patterns of this in a given area.

What is weather?

200
This refers to a group of individuals who belong to the same species and live in the same area.

What is a population?

200

These belts of cold wind travel south from the north pole and travel from east to west.

What are the easterlies?

200

This is the reason why water near the poles is salty and, as a result, sinks. 

What is the formation of ice?
200

This refers to all the living organisms and the environments they live in.

What is the biosphere?

200

This refers to the natural process in which certain gases trap sunlight energy in the earth’s atmosphere as heat    

What is the greenhouse effect?

300

This refers to an assemblage of different populations that live together in a defined area.

What is a community?

300
This characterization would describe a pocket of air that is warm because its molecules are spread out and fast moving.

What is low pressure?

300
Global ocean currents help bring this from the depths of the ocean to organisms near the surface that need it.

What are nutrients?

300

This refers to all of the earth's water, be it fresh water, salt water, water vapor in the atmosphere, or ice. 

What is the hydrosphere?

300

One of these is NOT a greenhouse gas: carbon dioxide, methane, nitrogen, or water vapor.

What is nitrogen?

400

This refers to all of the organisms that live in a place, together with their physical environment.

What is an ecosystem?

400

This is the official term that explains why an airplane flying from the north pole to the equator would have to overcorrect to the left to not end up too far right of its destination.

What is the Coriolis Effect?

400

Global ocean currents help bring this from the surface of the ocean to organisms in the depths that need it.

What is oxygen?

400

This refers to "all the usual solid stuff" - rocks, the continents, and the ocean floor. But it also includes the magma within the earth as well. 

What is the geosphere?

400

This phenomenon explains why temperate lands due east of a body of water tend to experience more snow than elsewhere.

What is lake effect snow?

500

This refers to a group of ecosystems that share similar climates and typical organisms.

What is a biome?

500

This term can be used to describe a dour human mood or a ship stuck on the ocean with no wind.

What is the doldrums?

500

This process refers to prevailing winds pushing ocean currents away from a continent, causing deep and cooler water to flow upward to take its place.

What is upwelling?

500

This refers to any nonliving factor that could affect an organism. Examples include sunlight, precipitation, soil, wind, or water. 

What is an abiotic factor?

500

This is the reason why coastal land tends to stay cooler in the summers and warming in the winter. 

What is a quality of water - it is slow to heat and slow to cool.
