Hydrology

Why is most of Earths freshwater is not available for human use.  

• because it's in the ground

• because it's frozen in ice caps and glaciers

• because of pollution

• because of global warmin

• 1%

• 2%

• 3%

• 5%

How do clouds form? 

• smoke from factories

• when condensation near land freezes

• when water vapor condenses and cools

What source of energy below is the most important in driving the water cycle?

• Geothermal energy changes water to steam so condensation can occur

• Sunlight heats up Earth's surface water creating the process of evaporation

• Wind helps change surface water into water vapor during the process of evaporation

• Gravity is necessary to pull water downhill when it rains thus allowing water to flow into rivers and streams

Refer to the diagram below of a student's lab setup of the water cycle. In this experiment, the total amount of water inside the container is measured at the beginning and then again after a full cycle has occurred. Which of the following best predicts the outcome of the experiment and explains why?

• The beginning amount of water in the container would be less than the ending amount of water in the container because the water evaporated, decreasing the water level.

• The beginning amount of water in the container would be more than ending amount of water in the container because the process of condensation increases the water level.

• The beginning and ending amounts of water in the container would be equal because the water that was evaporated increased the water level but then came back as precipitation which decreased the water level again

• The beginning and ending amounts of water in the container would be equal because the water that was evaporated decreased the water level but then came back as precipitation which increased the water level again.

Which of the following questions can BEST be answered by the data presented in the graph above?

• Is there a direct relationship between the density and salinity of ocean water?

• Is there an indirect relationship between the density and salinity of ocean water?

• Does the density of ocean water increase over time?

• Does the salinity of ocean water increase over time?

The diagram illustrates two types of currents are found in ocean waters.

Which of the following is the BEST explanation for why oceans have two types of currents?

• Surface currents are caused by wind whereas deep currents are caused by differences in density.

• Surface currents are caused by differences in density whereas deep currents are caused by wind.

• Surface currents are caused by temperature differences whereas deep currents are caused by changes in salinity.

• Surface currents are caused by changes in salinity whereas deep currents are caused by changes in temperature

Using the diagram, which of the following letters indicates where high tide is occurring and best explains why?

• Letters B and D indicate high tides, where the tidal bulges would occur because of the Coriolis Effect.

• Letters A and B indicate high tides, where the tidal bulges would occur because of the strong winds blowing across the oceans.

• Letters C and D indicate high tides, where the tidal bulges would occur because of the gravitational pull between the Earth and the moon

• Letters A and C indicate high tides, where the tidal bulges would occur because of the gravitational pull of the moon.
