Questions and Answers
How does latitude influence climate?
How does latitude influence climate?
Latitude affects climate by determining the amount of solar radiation an area receives, with equatorial regions receiving more direct sunlight compared to polar areas.
What role does elevation play in climate variation?
What role does elevation play in climate variation?
Elevation impacts climate as temperatures generally decrease with altitude, resulting in cooler conditions on mountaintops compared to lower valleys.
Explain how oceans contribute to the Earth's climate system.
Explain how oceans contribute to the Earth's climate system.
Oceans regulate global temperatures by absorbing, storing, and distributing heat, covering approximately 70% of Earth's surface.

Study Notes
Climate and Natural Environment
- Climate is a long-term weather pattern, usually over 30 years, for a region.
- Factors that influence climate include latitude, elevation, topography, ocean distance, and location on a continent.
- Common climate variables are temperature, precipitation, and wind pressure.
- Different regions have distinct climates (hot, cold, humid, dry).
- Climate is controlled by energy from the Sun and several interacting elements.
Key Climate Terms
- Latitude: Distance north or south of the Earth's equator.
- Elevation: Height above sea level.
- Topography: Arrangement of landforms (natural and artificial features).
- Precipitation: Rain, snow, sleet, or hail.
- Poles: Earth's northern and southern extremities.
- Equator: Imaginary line around Earth, dividing it into Northern and Southern hemispheres.
- Tropics: Imaginary lines parallel to the equator (Tropic of Cancer and Tropic of Capricorn).
Earth's Systems Affecting Climate
- Atmosphere: A mixture of gases surrounding Earth.
- **Oceans (Hydrosphere):**Cover about 70% of Earth's surface and play a vital role in regulating global temperatures due to their large size and heat storage capacity.
- Land (Lithosphere): Covers 27% of Earth; its topography (land shape) influences weather patterns.
- Ice (Cryosphere): A significant portion of fresh water; high reflectivity regulates temperatures.
- Biosphere: Includes all living organisms (plants, animals, humans) and their interactions.
Climate Regions
- Climate regions exist in bands around the Earth from the equator to the poles.
- Climate regions are usually shaped like belts.
- Temperatures decrease rapidly with altitude. Mountainous terrain disrupts regional climate patterns.
- Tropical climates are near the equator and receive direct sunlight.
Jet Streams
- Jet streams are high-altitude wind bands.
- Differing air masses (cold and warm) create jet streams (polar and subtropical).
