Study Notes
- Climate represents the long-term weather patterns of a specific location, typically established over 30 years.
- Human activities, like burning fossil fuels, contribute to climate change by increasing Earth's surface temperature.
- Natural events such as volcanic activity and ocean cycles can also cause climate change.
Atmospheric Effects
- Atmospheric circulation impacts climate due to temperature differences between Earth's poles and equator.
- Solar radiation is stronger at the equator, resulting in higher temperatures compared to the poles.
- Warm air rises at the equator, cools in the atmosphere, and descends near the poles, creating global wind patterns.
- The greenhouse effect occurs when gases in the atmosphere trap heat from the sun which warms the Earth and sustains life.
Heat Distribution
- Air circulation and global wind patterns help distribute heat across the Earth, which affects average temperatures.
- The equator receives more direct solar radiation, making it warmer than the poles.
- Oceans store and transport heat; water near the equator absorbs heat and moves towards the poles.
- As water approaches the poles, it releases heat into the atmosphere, then returns to the equator to repeat the cycle.
- El Niño is a Pacific Ocean weather event where winds move warm water eastward, occurring every two to seven years and can cause cooler, rainier winters in the southern states.
Landforms and Continents
- Continental drift, the slow movement of Earth's tectonic plates, influences climate over long periods.
- Continents moving from the equator towards the poles experience a shift from warm to cooler climates.
- The orographic effect happens when air masses meet mountain ranges, causing the air to rise, cool, and produce rainfall.
- A rain shadow effect occurs on the leeward side of mountains due to descending warm air absorbing moisture and creating a dry area.
Human Influence
- Burning fossil fuels releases gases like carbon dioxide, which trap heat and cause global warming.
- Deforestation and agricultural practices disrupt the Earth's water cycle and air and warm water circulation, also greatly changing the overall climate.
