â¢ Winds blow from areas of high pressure to areas of low pressure. â¢ Pressure belts are caused by the uneven heating of Earthâs surface by the sun. â¢ The Coriolis effect causes wind to appear to curve as it moves across Earthâs. surface. â¢ Global winds include the polar easterlies, the westerlies, and the trade winds.
The greenhouse effect increases the temperature of the Earth by trapping heat in our atmosphere. This keeps the temperature of the Earth higher than it would be if direct heating by the Sun was the only source of warming.reenhouse gases that are in the atmosphere absorb and then redirect some of this heat back towards the Earth. The greenhouse effect is a major factor in keeping the Earth warm because it keeps some of the planet's heat that would otherwise escape from the atmosphere out to space.
