Question

reviewing facts
section 1

1. what are the effects of the earth’s tilt, rota - tion, and revolution?
2. what are the differences in sunlight at the tropic of cancer, the tropic of capricorn, and the poles?
3. how is co₂ related to the green - house effect?

section 2

1. list three key factors that affect climate.
2. describe the changes in air pressure that occur during an el niño year. how do these changes affect wind patterns?
3. how do large bodies of water and mountains affect climate?

section 3

1. what are the major climate regions into which geographers divide the earth?
2. what main types of vegetation grow in the earth’s major cli - mate regions?
3. in what ways might the burning of fossil fuels affect a region’s vegetation?

Explanation:

1. Earth's tilt causes seasons, rotation causes day - night cycle, revolution is the orbit around the Sun.
2. Sunlight is more direct at Tropics, less at Poles. The Tropic of Cancer and Capricorn have more consistent sunlight than Poles.
3. CO₂ is a greenhouse gas. It traps heat in the atmosphere, contributing to the greenhouse effect.
4. Key climate - affecting factors include latitude, altitude, and proximity to water.
5. During El Niño, air pressure changes in the Pacific. It can reverse wind patterns.
6. Large bodies of water moderate climate, mountains can cause orographic precipitation and affect wind patterns.
7. Geographers divide Earth into regions like tropical, temperate, polar, etc.
8. Vegetation types vary by climate region, e.g., rainforests in tropical regions, tundra in polar regions.
9. Burning fossil fuels can increase CO₂ levels, causing climate change which may harm or change vegetation.

Answer:

1. Tilt causes seasons, rotation causes day - night, revolution is orbit.
2. More direct sunlight at Tropics, less at Poles.
3. CO₂ is a greenhouse gas contributing to the greenhouse effect.
4. Latitude, altitude, proximity to water.
5. Air pressure changes in Pacific, can reverse wind patterns.
6. Water moderates climate, mountains affect precipitation and wind.
7. Tropical, temperate, polar, etc.
8. Vary by climate region (e.g., rainforest in tropics, tundra in polar).
9. Can increase CO₂, cause climate change and harm vegetation.
