Use the map of world temperature zones to answer the following question.
What zone is the tropical zone?
Zone C
200
What are the three kinds of temperate Marine climates?
humid subtropical, marine west coast, and Mediterranean
200
Which of the following is probably the main cause of ice ages?
Volcanic activity
Solar energy
Continental movement
Earth's orbit
Earth's orbit

Explain how human activities are affecting the temperature of the atmosphere.
Many human activities are increasing the level of greenhouse gases in the atmosphere and producing changes in climate worldwide, causing global temperatures to rise.
300
Use the map of world temperature zones to answer the following question.
What zone is the polar zone?
A and E
300
Permanently frozen soil.
permafrost
300
What three things do scientists study to learn about ancient climates?
pollen, tree rings, and ice cores
300
Thick tree rings in a cool climate suggest a longer warm season. Thick tree rings in a dry climate suggest a rainier wet season. What conclusion can you draw about the effect of climate on tree growth?
Trees develop thicker rings in years when they grow more because their needs are met.
400
Use the map of world temperature zones to answer the following question.
What zone is the temperate zone?
B and D
400
What factors are used to define climates?
Scientists classify climates according to two major factors: temperatures and precipitation. Koppen system also looked at the distinct vegetation in different areas.
400
What are three natural factors that can cause climate change?
Earth's position
Volcanic Activity
Movement of Continents
400
How is Earth's climate affected by major volcanic eruptions?
Aerosols and ash from eruptions can reduce the amount of solar radiation reaching Earth's surface, causing climates to cool.
500
What factors affect temperature?
Temperature is affected by latitude, altitude, distance from bodies of water, and ocean currents.
500
What are the six main climate regions?
Tropical Rainy
Dry
Temperate Marine
Temperate Continental
Polar
Highland
500
What important principle do scientists follow when studying ancient climates?
If plants or animals today need certain conditions to live, then similar plants and animals in the past also required those conditions.
500
How does the movement of continents explain changes in climate over millions of years?
As continents moved, their latitudes changed, global patterns of wind and ocean currents changed, and mountains formed.
