Unit 4 - Review

The sun's energy evaporates water from the surface of Earth. This water is the source of

• respiration

• ozone depletion

• precipitation

• transpiration

Water is found in an underground reservoir is called a(n)

• Aquifer

• Spring

• Well

• Reservoir

What are the most abundant elements in ocean water besides oxygen and hydrogen?

• potassium and chlorine

• sodium and chlorine

• sodium and magnesium

• hydrogen and oxygen

Which number represents the Pacific Ocean?

• 7
• 2
• 4
• 9

After precipitation is infiltrated, groundwater that travels into the saturated soil zone becomes part of

• the ocean 
• surface runoff
• aquifers
• precipitation

Precipitation will increase in areas where there is

• less transpiration and less run-off.

• lower temperatures and more evaporation.

• lower temperatures and less evaporation.

• higher temperatures and more evaporation.

Once the sun's energy reaches the earth's atmosphere through radiation, it is circulated within the atmosphere and oceans through _____________.

• conduction

• convection

• radiation

In the oceans, warmer water stays closer to the surface, while the colder water sinks . The water then moves around the ocean basin. This is causes by

• ocean currents

• tidal waves

• wind drift

• plate tectonics

a large mass of ice that is formed on land and moves slowly down a slope or valley because of gravity

• drought

• icicle

• glacier

• groundwater

Louisa put a bowl of water and a bowl of sand in the sun. She put a thermometer in each bowl. Then she recorded the temperature at the start and after 30 minutes. After 30 minutes, the sand had heated more than the water.

Louisa’s experiment proved that

• different materials absorb the same amount of heat.

• different materials heat up at different rates.

• sunlight heats liquids more than solids.

• sunlight does pass through water.
