Briefly describe three theories scientists have proposed to explain natural climate changes. _____

1. Volcanoe eruptions have put a lot of gas and ash into the atmosphere not allowing sunlight and decreasing temperatures. 2. The shape of Earth's orbit has changed and the tilt of the Earth has changed. Scientists think this is causing a change in climate. 3. The energy the sun gives off has changed and is affecting the Earth's temperature.

If you travel in a straight line from Omaha to Sacramento, how many different types of climates do you cross?

5

Which zones are polar zones?

A & E

Which continent lies almost completely within the tropical zone?

Africa

Where in the US can you find a Mediterranean climate suited for growing loives and grapes?

Along the southern coast of CA

Because of its high ____, Mount Chimborazo has a cool climate all year.

Altitude

Which continent lies almost completely within a polar zone?

Antarctica

Which climate regoins would you cross if you traveled from west to east across the widest part of Texas?

Arid, semiarid and humid subtropical

Which zones are temperate zones?

B & D

Which zone is the tropical zone?

C

In which states does the marine west coast climate occur?

California, Oregon and Washington

People add the greenhouse gas ____ to the atmosphere by burning wood, oil, natural gas, and coal.

Carbon Dioxide

Which of the following has caused repeating 100,000-year cycles of ice ages in the past?

Changes in Earth's orbit and the tilt of its axis

Prevailing winds blow from the Pacific Ocean toward two cities separated by mountains. City A is on the leeward side of the mountains and city B is on the windward side. Which city is likely to have a wetter climate? Explain.

City B will be a wetter climate. With a windward side, the air rises over the mountains and if it is moist, it will make clouds. This can make rain or snow which makes it a wet climate.

One possible explanation for past climate changes is the movement of Earth's ___ from their previous positions.

Continent

The farther you live from an ocean, the more likely your climate will be a ___

Continental climate

Regions that receive less than 25 centimeters of rain annually are called____

Deserts

T or F An arid or semiarid climate occurs where precipitation is GREATER than potential evaporation.

False Less

T or F Oceans make the temperatures of nearby land MORE extreme.

False Less

T or F The main factors that affect an area's TEMPERATURE are prevailing winds and mountains.

False Precipitation

The gradual increase in teh temperature of the atmosphere is known as ____

Global Warming

Describe some of the effects of global warming. What are some possible solutions to this problem?

Global warming is causing a lot of problems. Our glaciers are melting quicker, we are having more droughts and water shortages. CA is in one right now. If we help to change our carbon dioxide footprint on the earth, this will help slow down global warming. We can recylce things, use less energy and buy more green products.

A tropical wet climate exists in the US only in ____

Hawaii

A colder type of climate called ____ is found at the tops of mountains and is surrounded by other climate regions.

Highlands

Thickness of rock layers

Give the names of the zones in which South America lies. ____

Tropical and Temperature

Describe how precipitation is used to classify tropical rainy climates. ____

Tropical climates are wet all year long because it rains a lot. With all the moisture in the air, it keeps it wet and able to rain.
