Wind

17) The sun is the major source of energy for events on the surface of the earth including wind, ocean currents, and waves

18) Uneven heating of the Earth’s surface is responsible for making the weather on Earth

19) Convection is heat transfer through liquid or gas.

20) Conduction is heat transfer through direct contact with solids

21) The equator receives the greatest amount of direct sunlight throughout the year

22) The pole regions receive the least amount of sunlight throughout the year.

23) Large convection currents are formed because of the temperature differences between the equator and the poles.

24) Theses convections currents produce global wind systems.

25) The rotation of the earth makes the large wind systems curve 25) The rotation of the earth makes the large wind systems curve. This is called the Coriolis Effect.

26) Warm air rises. The farther it gets away from the Earth, the colder it gets. As it gets colder, it becomes more dense. It then falls back towards Earth. This continual movement of air in a circular pattern in the atmosphere is known as convection currents.

27) Wind is formed by differences in temperature and pressure in air.

28) Cold air is more dense and has more pressure than warm air.

29) Wind always blows from areas with more density to areas with less density.

30) Warm air rises. This warm air then makes an area of low pressure.

31) Waves transfer energy from one place to another 31) Waves transfer energy from one place to another. Waves in oceans and lakes are caused by wind blowing over the surface of the water.

32) The Coriolis Effect is caused by the Earth’s rotation.
