1.

Scientists believe that the Earth's early atmosphere lacked __________ gas because photosynthetic organisms did not yet exist.

a)

hydrogen

b)

nitrogen

c)

oxygen

d)

sulfur

2.

This gas is found in the stratosphere where it helps protect us from UV radiation.

a)

ozone

b)

oxygen

c)

nitrogen

d)

carbon dioxide

3.

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

a)

conduction

b)

convection

c)

radiation

d)

translocation

4.

Heat would best be transferred by conduction between

a)

a candle and the air.

b)

an oven and a glass dish.

c)

a stove and a copper pot.

d)

water and a wooden spoon.

5.

Josh did an experiment, recording the changes in temperature in sand and water when exposed to a light source, and then when the light source was removed. Josh decides that

a)

sand and water conduct heat the same.

b)

sand conducts heat better than water.

c)

water conducts heat better than sand.

d)

neither sand nor water conducts any heat.

6.

Most of the energy needed for all the processes on earth comes directly or indirectly from the sun. There is no medium or material connecting the sun to the earth. Therefore, the only type of heat transfer possible to transfer energy from the sun to the earth is

a)

condensation.

b)

conduction.

c)

convection.

d)

radiation.

7.

Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the:

a)

mesosphere

b)

stratosphere

c)

thermosphere

d)

troposphere

8.

Warm air rises at the equator and cold air sinks at the poles creating

a)

tornadoes.

b)

hurricanes.

c)

convection currents.

d)

the Coriolis effect.

9.

During the day, the Sun heats the ocean and the ocean stores this energy. During the evening the land cools and the ocean transfers the energy back to the air. As a result you get a cool breeze. Which direction would the breeze blow in this illustration?

a)

left to right

b)

right to left

c)

top to bottom

d)

there would be no breeze

10.

The diagram shows the global wind pattern in the lower atmosphere. What is the main factor that determines the global wind pattern?

a)

the directions of ocean currents

b)

uneven landforms on Earth’s surface

c)

Earth's yearly revolution round the Sun

d)

uneven heating of Earth's surface by the Sun

11.

What weather conditions could we expect to see as the low pressure area moves through Georgia?

a)

a hurricane

b)

hot, sunny conditions

c)

winds and increased rain

d)

a huge drop in temperature

12.

The uneven heating of the atmosphere by the sun's energy creates pressure differences.

a)

formation of clouds

b)

generation of winds

c)

occurrence of lightning

d)

an increase in humidity

13.

The weather forecast for a place indicates bad weather for a short period of time. As the front moves in, very tall clouds form. What would the weather map of the place look like?

a)
b)
c)
d)
14.

Check out the map showing tornado alley in the U.S. Although tornadoes can occur anywhere, they are most likely to occur when what conditions exist?

a)

warm, dry air meets cold, dry air

b)

cold, dry air meets warm, moist air

c)

the jet stream causes an extreme low-pressure area

d)

differing wind directions and wind speeds cause the air masses to swirl horizontally

15.

You are watching the weather forecast and the weatherman says that strong thunderstorms and possible tornadoes are likely to form in your area. Which explanation about pressure systems below would the weatherman likely use to explain the severe weather forecast?

a)

Low pressure systems are associated with warm air or dry air

b)

High pressure systems are associated with warm air or dry air

c)

Low pressure systems are associated with cold air or moisture rich air

d)

High pressure systems are associated with cold air or moisture rich air

16.

The rate of evaporation depends on four main factors : water body size, heat energy, atmospheric pressure and air movement. Warm waters and high winds often result in the development of hurricanes over the world's oceans because of increased evaporation. Where, on this map, is the LEAST likely location for a hurricane to form?

a)

1

b)

2

c)

3

d)

4

17.

Clouds are made up of water droplets. Which statement BEST describes how the water droplets get into the air to form clouds?

a)

Water droplets in clouds are a result of precipitation.

b)

The water droplets in clouds get into the air through absorption.

c)

Clouds form on the ground and the wind blows them up into the air.

d)

Water evaporates from the surface of the Earth and then condenses to form clouds.
