  • The Earth's atmosphere is divided into five layers:
    • Exosphere
    • Thermosphere
    • Mesosphere
    • Stratosphere
    • Troposphere
    • The troposphere is where we live and where nearly all life and all weather occur
    • The stratosphere contains the ozone layer and is where military planes can fly
    • The mesosphere is the coldest layer and protects Earth from meteoroids
    • The thermosphere has very high temperatures, over 2000 degrees Fahrenheit, and is where space begins
    • The exosphere is the outermost layer, extending into outer space
  • The atmosphere consists of layers of gases that surround the Earth, with the two most abundant gases being oxygen and nitrogen
  • Air Pressure is the force of air pressing down on Earth or the weight of air, with higher altitude resulting in less air pressure
  • The troposphere is the layer closest to the surface of Earth, where nearly all life and all weather occur, and where the peak of Mt. Everest is located
  • The stratosphere contains the ozone layer, which warms up the upper region by absorbing UV rays heat and protects living organisms from harmful UV rays
  • The mesosphere is the coldest layer of the atmosphere, protecting Earth from meteoroids that usually burn up in this layer
  • The thermosphere has very high temperatures, over 2000 degrees Fahrenheit, and is where space begins, with the International Space Station orbiting Earth in this layer
  • The exosphere is the farthest layer extending from the thermosphere into outer space, gradually blending into outer space and being cold
  • The troposphere is the lowest layer, extending from the surface to an altitude of approximately 12 km.
  • The mesosphere extends from about 50-85 km above Earth's surface.
  • The thermosphere extends from about 85-700 km above Earth's surface.
  • The exosphere extends beyond 700 km above Earth's surface.
  • The ionosphere is located between 60-1000 km above Earth's surface and is divided into three layers based on electron density.
  • The ozone layer is found in the stratosphere and helps protect Earth from UV radiation.
  • Stratosphere extends 12-50 km above Earth's surface.
