Cycles of Matter

What stage occurs in the water cycle when water vapor cools (goes from gas to liquid)?

• evaporation

• condensation

• sublimation

• transpiration

What step of the water cycle is when PLANTS give off water vapor from photosynthesis?

• evaporation

• transpiration

• sublimation

• condensation

What makes up 78% of the air we breathe?

• oxygen

• nitrogen

• fixed nitrogen

• carbon

Which of the following best explains why nitrogen FIXATION must take place?

• Atmospheric nitrogen is unusable to plants and animals

• Nitrogen must be returned to the atmosphere

• Animals must breathe in nitrogen

• Nitrogen gets "stuck" in the soil and must be untrapped

What is the overall purpose of photosynthesis?

• To use energy from the sun to produce food for the plant
• To use energy from the sun to produce oxygen for animals to breathe
