Study Notes
Earth's Movement and Time
- Earth rotates on its axis, completing a full rotation every 24 hours, resulting in day and night.
- The eastward rotation means that the day begins earlier in the eastern regions of the planet.
- Time zones are established in standard intervals where neighboring zones differ by one hour.
Seasons
- The tilt of Earth's axis and its elliptical orbit around the sun causes seasonal changes.
- Direct sunlight shifts north and south of the Equator, influencing seasonal variations.
- One complete revolution around the sun takes approximately 365.25 days.
Climate vs. Weather
- Weather refers to the atmospheric conditions at a specific time and place.
- Climate is defined as the average weather patterns of a location over many years.
Variability in Temperature and Precipitation
- Variations in temperature and precipitation influence regional climates, affecting ecosystems and human activity.
- The main climatic descriptors include precipitation (rain, snow, etc.) and temperature.
Earth's Climate Regions
- Tropics: Located between the Tropic of Cancer and Tropic of Capricorn; typically characterized by high temperatures.
- Temperate Zone: Mid-latitude regions experience hot summers and cold winters, with moderate spring and fall.
Ecosystems and Biomes
- Ecosystems consist of interdependent communities of organisms and their environments.
- Key ecosystems include forests, grasslands, and cold climates.
- A biome is identified as a large area with similar ecosystems and associated flora and fauna.
Vocabulary
- Equinox: A time when day and night are of equal length worldwide.
- Solstice: A time when one hemisphere experiences the longest day, while the other has the shortest.
- Altitude: The height above sea level, which can affect temperature and climate.
