  • kevin Kyalo Kenya how are air movements in the atmosphere??
    2014-08-20 11:08:00

    • ngum jai raymond Cameroon air bodies are either hot or cold. these air bodies move in varied directions, either towards each other or away. the force of the air masses are also different. cold air is generally heavier than warm air. the warm air masses flow from the tropical regions toward the poles while the cold air masses move from the poles towards the tropics

      2014-08-25 17:08:46
    • Sefala niger Mapotse South Africa Cold air is heavier it flows lower than the warm air which is lighter.
      2014-08-25 11:08:31
    • Luzmila Alvarez United Arab Emirates For the differences of pressure from the high-pressure region to the low-pressure region. IThe air moving from high to low pressure follows a spiralling route, outwards from high pressure and inwards towards low pressure. This is due to the rotation of the Earth beneath the moving air, which causes an apparent deflection of the wind to the right in the Northern Hemisphere, and to the left in the Southern Hemisphere.
      2014-08-22 10:08:46
    • Atash Shiyarwala Canada As the air heats unevenly it creates pressure differential, air moves from cold air to warm air.

    • Cody Baynard United States of America yes usa has improved on dirty energy they have been working on my eco frendly energy like hydro, wind and solar energy
      2014-08-25 17:08:16
    • Jeanine Quick United States of America In the US I would say that our improvements in sustainable and clean energy is focused mostly on solar and wind. As far as natural gas, there is a heated debate over the benefits and environmental detriment. Natural gas burns cleaner but, frack drilling is threatening the water table, stream and systems and the exhaust is making people and livestock sick.
