Science

• it extends about 90km above earth. In this layer, temperature decreases with height. This is the coldest region of the atmosphere.

  Mesosphere
• the ___&& is very dry with little water vapor present.

  Stratosphere
• the ______ is the lowest layer of the atmosphere. It extends about 14 to 18km from Earths surface.

  Troposphere
• the topmost layer part Of earths atmosphere js the _______. The Suns radiation strips off some of the electrons from the gases in the thermosphere, making them electrically charged ionized.

  Thermosphere
• the exosphere begins at the top of the thermosphere and continues until it merges into space. It is composed primarily of hydrogen and helium.

  Exosphere
• The airs mass produces a downward force that exerts pressure in the surface kg earth. Bt he pressure exerted by air is called

  atmospheric pressure.
• Airmasess originated from the sea and are moist.

  Maritime air
• come from land srebdry and called continental air masses

  Continental air masses
• wind that blows from the sea toward the land.

  Sea breeze
• wind that blows from the land to the sea.

  Land breeze
• the movement of water from the atmosphere to earths surface. When water vapor jn the clouds become too heavy to remain suspended in the sir, it falls back to earth either in a liquid state (rain) or solid state (snow, freezing raining, sleet, or hail.)

  Precipitation
• when frozen material doesn't melt,.

  snow
• rain that freezes and solidifies upon impact with cold surface.

  freezing rain
• falls out of cloud's when closure becomes heavybwiry condense water droplets.

  rain
• small-scale weather system in which lightning and thunder are produced by a funnel-shapped cumulonimbus cloud.

  Thunderstorm
• buildup discharge if electrical energy between positively and negativelu charged areas.

  lightning
• low pressure system that forms over tropical oceans, and brings winds and thunderstorm.
