Weathering moves soil, erosion breaks down rocks, deposition adds organic material, and decomposition transports materials.

Weathering breaks down rocks, erosion moves materials, deposition drops materials in a new location, and decomposition adds organic matter.

CFCs increase greenhouse gases, leading to global warming.

CFCs deplete the ozone layer, leading to increased UV radiation.

CFCs cool the stratosphere, causing cloud formation.

CFCs thicken the ozone layer, reducing UV radiation.

El Niño causes global cooling, while La Niña causes global warming.

El Niño causes floods in some areas and droughts in others, while La Niña has opposite effects.

El Niño and La Niña have identical effects on global weather patterns.

El Niño and La Niña only affect weather patterns in the Pacific Ocean.

Mountains increase precipitation on both sides, creating rainforests.

Mountains block precipitation on one side, creating dry regions on the leeward side.

Mountains have no impact on local climate.

Mountains cause increased humidity on all sides.
