The ability of water molecules to attract other water molecules is called:

• Cohesion

• Adhesion

• Cooperation

• Prohesion

The ability for water molecules to attach to non-water substances is called:

• Cohesion

• Adhesion

• Prohesion

• Condensation

The term Polarity describes how water...

• has a positive charge on one side and negative on the other

• freezes faster that any other liquid

• has balanced electrical charges

• is attracted to Earth's magnetic poles

As water freezes into a solid:

• It expands and becomes less dense

• Its shrinks and becomes more dense

• It takes up the same amount of space

• It releases cold particles that cool the surrounding area

Capillary Action is the combination of:

• Cohesion and Adhesion to move water molecules through roots and veins

• Hydrogen Bonding and Polarity to move water molecules through oceans

• Cohesion and Polarity to move water through the water cycle

• Adhesion and pH to dissolve solids into liquids

Surface Tension between water molecules is created by:

• Cohesion

• Adhesion

• Solvency

• Capillary Action

Nitrogen Fixing is conducted mainly by:

• Plants performing photosynthesis

• Animals performing Respiration

• Bacteria living in soil and on roots

• Precipitation of Nitrogen in the atomphere

In the water cycle, rainfall is called

• Evaporation

• Condensation

• Precipitation

• Sublimation

Evaporation is the change is matter from a:

• gas to a solid

• gas to a liquid

• liquid to a gas

• liquid to a solid

Humans increase the carbon in the atmosphere by which TWO processes?

• Combustion

• Respiration

• Photosynthesis

• Carbon Fixation

• Precipitation
