Unit 4 Review

You move a 12-newton box up a 6-meter ramp. In order to find out how much power you created, what would you need to know?

• The mass of the box

• The slope of the ramp 

• The direction the box moved

• How long the task took

What causes the formation of ocean currents?

• rotation of Earth on its axis

• change in the magnetic field of Earth

• temperature differences of water in the ocean

• movement of tectonic plates under Earth’s surface

The oceans make up 70% of Earth's surface. They regulate the overall temperature of the earth by absorbing a great deal of solar energy and heating up slowly. What is true about the oceans' release of heat?

• The oceans release heat rapidly and add to the greenhouse effect.

• The oceans release heat more slowly than the land.

• The oceans release heat more rapidly than the land.

• The oceans release heat at the same rate as the land.

As the air on the surface of the Earth warms, what happens to the density of the air?

• It decreases.

• It increases.

• It remains constant.

• It decreases, then increases.

How do the air temperatures above land and water vary during day and night?

• The air above land will be at a lower temperature than the air above water during the day and at a higher temperature than the air above water at night.

• The air above land will be at a higher temperature than the air above water during the day and at a lower temperature than the air above water at night.

• The air above land will be at a higher temperature than the air above water at all times of the day and night.

• The air above land will be at a lower temperature than the air above water at all times of the day and night.

What explains why the air is sinking at point Y?

• The land is cooler than the water at night, so the air cools, is more dense, and sinks.

• The land is warmer than the water at night, so the air warms, is less dense, and sinks.

• The land is cooler than the water at night, so the air cools, is less dense, and sinks.

• The land is warmer than the water at night, so the air warms, is more dense, and sinks.

As part of the water cycle, water from Earth’s surface enters the clouds and finally falls back to the ground in the form of rain. What is the correct sequence of processes water undergoes?

• evaporation → condensation → precipitation

• precipitation → condensation → evaporation

• condensation → evaporation → precipitation

• evaporation → precipitation → condensation
