1.

What is the source of the thermal energy that heats our planet’s atmosphere?

a)

Earth's core

b)

Green plants

c)

The Sun

d)

Fossil Fuels

2.

The Sun warms the atmosphere and drives convection currents because -

a)

warm air is less dense, so it rises.

b)

the warmed air cools and makes rain.

c)

the cooler land pushes away warm air.

d)

warm air, in contact with cool air, rotates.

3.

What is one effect of the uneven heating of Earth caused by the Sun?

a)

Rotation of Earth

b)

Generation of wind

c)

Oceans losing salt

d)

Plants failing to grow

4.

An illustration of how a convection current creates a wind, called a land breeze, is provided.Which of the following best explains what creates this convection current?

a)

The rotation of Earth makes the air above it rotate, but not the same over land and water.

b)

Because of its mass, Earth’s gravity creates a high pressure area over both the land and water.

c)

Salt in the ocean makes it more dense than the land, so its gravity pulls more on the air above it.

d)

During the evening, the land cools off more quickly than the water, so the air is different temperatures.

5.

Convection is the type of heat transfer that occurs in which of the following?

a)

Empty space

b)

Solid materials

c)

Liquids and gases

d)

Objects in contact

6.

The illustrations show the usual wind pattern at the shore during the day and night.What is the most important factor that creates these wind patterns?

a)

Most people visit the shore during the day and are not there at night.

b)

The air above the land heats up and cools off more quickly than the air over the water.

c)

The seawater is capable of having salt dissolved in it, but the land cannot.

d)

The shape of the land is constantly being changed by the motion of the seawater.

7.

What is a type of energy that spreads out as it travels?

a)

Radiation

b)

Conduction

c)

Convection

d)

Electrical

8.

What is the process by which heat is transferred through direct contact?

a)

Radiation

b)

Conduction

c)

Convection

d)

Boiling

9.

Differences in density create differences in air

a)

temperature

b)

pressure

c)

luminosity

d)

quality

10.

a)

higher

b)

lower

11.

The higher you rise into the atmosphere, the _________ the air pressure becomes.

a)

higher

b)

lower

12.

Which of the following affects surface ocean currents?

a)

wind

b)

tides

c)

differential heating of sea water

d)

13.

Sabrina noticed a lot of puddles on her driveway after it rains on Tuesday afternoon. On Wednesday morning she notices the puddles are gone. Why?

a)

The wind blew the puddles away

b)

They disappeared

c)

The suns energy caused the water to evaporate

d)

The suns energy caused the water to precipitate

14.

Where does energy that heats the land, water, and air come from?

a)

Batteries

b)

Lamps

c)

The sun

d)

The moon

15.

Andres goes to the beach on Saturday. Andres notices that the sand at the beach is hot but the water in the ocean is too cold to swim in. Why?

a)

Land heats up faster than water

b)

Water heats up faster than land

c)

Andres used a lamp to heat up the sand
