Earth Science: Motion and Climate

Questions and Answers

How does Earth's movement explain the days and seasons?

The tilt of Earth's axis and its orbit around the sun create seasons, while rotation creates day and night.

How is climate different from weather?

Climate is the average weather over many years, while weather is the current condition of the air and sky.

Why do temperatures and precipitation vary?

Temperatures and precipitation vary due to factors like geography, season, and climate zones.

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.
