Heat can move when two objects touch through this process.

What is Conduction? 

100

Earth’s surface does not warm evenly because of this effect.

What is uneven heating? 

100

The line at 0° latitude is called this.

What is the equator? 

100

Nonliving parts of an ecosystem.

What is abiotic? 

100

An organism that makes its own food.

What is an autotroph or a producer? 

100

A close relationship between two species.

What is symbiosis? 

200

Heat moves through fluids like air and water because warm parts rise and cool parts sink.

What is convection?

200

This movement of air or water is driven by changes in temperature and density.

What is a convection current? 

200

Lines that run north to south and measure east–west positions.

What is longitude? 

200

A group of the same species living in one area.

What is population? 
200

Organisms that cannot make their own food.

What are heterotrophs or consumers? 

200

Both species benefit in this type of relationship. (+,+)

What is mutualism? 

300

Heat from the Sun reaches Earth through this type of transfer.

What is radiation? 

300

Warm air rises because it has less of this physical property.

What is density? 

300

The line at 0° longitude. 

What is the Prime Meridian? 

300

All the living and nonliving parts interacting in one place. 

What is an ecosystem? 

300

Tiny animals that feed on dead material and recycle nutrients.

What is a detritivore? 

300

One species benefits; the other is unaffected.(+, 0)

What is commensalism? 

400

This type of heat transfer always moves from warmer areas to cooler ones.

What is thermal energy? 

400

The top 400 meters of the ocean current is driven by wind?

What is a surface current? 

400

The imaginary lines that run east–west and measure north–south positions.

What is latitude? 

400

All the ecosystems build biomes.  All of the biomes build the  ___________.  

What is the biosphere? 

400

Animals that eat only plants.

What is a herbivore? 

400

One species benefits while harming the other. (+, -)

What is parasitism? 

500

This type of heat transfer does not require molecules to move or touch.

What is radiation? 

500

This deep ocean current is driven by salt and heat. 

What are thermohaline currents?

500

These divide Earth into northern and southern halves.

What are hemispheres? 

500

All of the populations living in an area.

What is community? 

500

An organism that eats both plants and animals.

What is an omnivore? 

500

When one organism hunts another for food.

What is a predator-prey relationship?
