OVERVIEW: This unit addresses the interaction of atmospheric conditions and the effects of these on weather and climate.
Georgia Performance Standards to be covered:
S6E2. Students will understand the effects of the relative positions of the earth, moon and sun.
c. Relate the tilt of the earth to the distribution of sunlight throughout the year and its effect on climate
S6E4. Students will understand how the distribution of land and oceans affects climate and weather.
a. Demonstrate that land and water absorb and lose heat at different rates and explain the resulting effects on weather patterns.
b. Relate unequal heating of land and water surfaces to form large global wind systems and weather events such as tornadoes and thunderstorms.
c. Relate how moisture evaporating from the oceans affects the weather patterns and weather events such as hurricanes
Students will understand that:
• Because the Earth turns daily on an axis that is tilted relative to the plane of the Earth's yearly orbit around the sun, sunlight falls more intensely on different parts of the Earth during the year. The difference in heating of the Earth's surface produces the planet's seasons and weather patterns.
• The cycling of water in and out of the atmosphere plays an important role in determining climatic patterns.
• Heat energy carried by ocean currents has a strong influence on climate around the world.
• The sun is the major source of energy for phenomena on the Earth's surface, including winds, ocean currents, and waves.
• Waves transfer energy from one place to another. Waves in oceans and lakes are caused by wind blowing over the surface of the water.
• Ocean currents influence the weather in coastal areas. Currents can be caused by wind, differences in salinity, differences in water temperatures caused by uneven heating of the Earth, the Coriolis Effect which is a consequence of the Earth's rotation, and the gravitational pull of celestial bodies
OVERARCHING ESSENTIAL QUESTION
