• the equator

Multiple Choice

Decreasing ocean temperature causes the density of the water to ______.

• decrease

• increase

• stay the same

• fluctuate

Multiple Choice

______ causes deep ocean currents

• The Coriolis Effect

• gravity

• wind

• density differences

Multiple Choice

______ causes surface currents.

• The Coriolis Effect

• gravity

• density differences

• wind

Multiple Choice

The average weather conditions of a region--

• daily temperature

• weather

• climate

Multiple Choice

The main reason that we have currents in the ocean and air is

• the sun heats the air and ocean evenly everywhere
• the heat inside the earth heats the ocean and the ocean heats the air
• the sun cannot heat both the air and water, so one must heat the other
• the sun heats air and water more at the equator because it receives more direct sunlight

Multiple Choice

The condition of the air outdoors is-

• climate

• weather

• average temperature

Multiple Choice

What causes winds to form on Earth?

• solar energy
• ocean currents
• elevation differences
• uneven heating of the Earth by the sun

Multiple Choice

Which of the following is true about the unequal heating of land (sand) and water?

• land/sand heats up and cools off faster than water
• water heats up and cools off faster than land/sand
• land and water heat and cool at the exact same rate
