Hydrosphere Review

Water Distribution

The hydrosphere is all of the waters on the earth's surface, both fresh- and saltwater. It also can include the water over the earth's surface (think clouds).

Water moves through the hydrosphere using the water cycle. A keep thing to remember is that the amount of water in the hydrosphere is always the same. It might be in different forms but the amount never changes.

Multiple Choice

What occurs during the process of condensation in the water cycle?

a change in state from solid to liquid

a change in state from liquid to gas

a change in state from gas to liquid

a change in state from liquid to solid

Multiple Choice

Which step in the water cycle involves returning of fresh water to the Earth?

precipitation

evaporation

respiration

condensation

Multiple Choice

Which BEST describes how the total amount of water present in the hydrosphere varies over time?

The total amount of water in the hydrosphere decreases over time due to the process of evaporation.

The total amount of water in the hydrosphere remains the same over time, but changes form due to the water cycle.

The total amount of water in the hydrosphere increases over time due to the process of precipitation.

The total amount of water in the hydrosphere both decreases and increases over time due to competing processes such as evaporation and precipitation.

Where is all of our water?

Most of all the water is located in the ocean which makes it unusable as drinking water for us.

Poll

Where is the most amount of freshwater located?

soil

lakes

groundwater

ice and glaciers

Multiple Choice

What gives the water cycle the energy to continue?

Stewardship and Water Quality

Stewardship - taking care of water source
pH - 0-14 scale determining how acidic (0-6) or basic (8-14) something is.
Temperature - temperature changes can effect aquatic ecosystems.
Nitrates/Phosphates - nutrients found in fertilizer
Dissolved Oxygen - the amount of oxygen stored in water
Turbidity - how clear the water is
Bioindicators - specific organisms that are used to judge the health of a water system
