What do we call the average, year-after-year conditions of temperature, precipation, winds, and clouds in an area? Climate
What causes the seasons? The tilt of Earth's axis as it revolves around the sun
What are the 2 major factors that classify climates? precipitation and temperature
What climate zone lies between 23.5 degrees and 66.5 degrees north and south latitudes? temperate
What winds change direction with the seasons? monsoons
What is the name of the climate region that receives less than 25 cm of rain annually? desert
What climate region has permafrost, mosses, lichens, and wildflowers? tundra
What temperature zone lies between the tropical and polar zones? temperate
What are the tropical grasslands found in the tropical wet-and-dry climate called? savannas
What climate region has short, cool summers, bitterly cold winters, and permafrost? tundra
What climate region is found at the tops of mountains and is surrounded by other climate regions? highlands
What region has forests and plenty of rain fall all year? rain forest
What do all three temperate marine climates have in common? They all have mild winters.
What is the gradual increase in the temperature of the atmosphere? global warming
What type of climate would you be likely to live in if you lived far from an ocean? continental
What are the characteristics of summer? longer days and more direct rays from the sun
What type of climate do the Great Plains and the Rocky Mountains have? semiarid
Finish this sentence: If an organism today needs certain conditions to live, then a similar organism that lived in the past... needed similar conditions
What happens to the sea level during an ice age? It lowers.
What has happened to the level of carbon dioxide in the atmosphere over the past 200 years? increased steadily
What does the ozone layer do? filter harmful ultraviolet radiation from the sun
What do the chlorine atoms in the statosphere do to the ozone? break the O3 (ozone) into oxygen (O2)
Where are the sun's rays least direct? near the poles
What do scientists predict the effect will be of banning the use of chlorofluorocarbons? gradually restore the ozone layer
How does the climate on the leeward side of a mountain differ from the climate on the windward side of a mountain? The windward side of the mountain receives rain and snow, but the leeward side is in the rain shadow and will have a drier climate.
In what climate zone is the tundra found? polar zone
What temperate continental climate has short cool summers and long, bitterly cold winters? subarctic
Where does El Nino form? tropical Pacific Ocean
What effect does altitude have on the temperature of Mt. Kilimanjaro? increased altitude lowers the temperature

During what did glaciers cover much of the Earth's surface? ice age
Into what 2 states did the most recent major ice age extend? Iowa and Nebraska
How can continental movements cause climate changes? When continents move, land and sea move causing changes in winds and ocean currents which causes climate change.
How might carbon dioxide cause global warming? by trapping more heat in the atmosphere
