  2. Mar 13, 2018 · The Earth's atmosphere protects and sustains the planet's inhabitants by providing warmth and absorbing harmful solar rays. In addition to containing the oxygen and carbon dioxide, which living things need to survive, the atmosphere traps the sun's energy and wards off many of the dangers of space.

    • The Atmosphere's Importance. We are lucky to have an atmosphere on Earth. The atmosphere supports life and is also needed for the water cycle and weather.
    • The Atmosphere and Living Things. Most of the atmosphere is nitrogen, but it doesn't do much. Carbon dioxide and oxygen are the gases in the atmosphere that are needed for life.
    • The Atmosphere and the Sun’s Rays. The atmosphere protects living things from the Sun’s most harmful rays. Gases reflect or absorb the strongest rays of sunlight (Figure below).
    • The Atmosphere and Earth’s Temperature. Gases in the atmosphere surround Earth like a blanket. They keep the temperature in a range that can support life.
  3. Dec 11, 2019 · It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. Earth’s atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere.

    Earth’s atmosphere is a thin blanket of gases and tiny particles—together called air. Without air, the Earth would just be another lifeless rock orbiting the Sun. Although we are rarely aware of it, air surrounds us. We are most aware of air when it moves, creating wind. Like all gases, air takes up space. These gases that make up our air are packe...

    Plants and animals need the gases in the air to survive, and the protection the atmosphere provides helps sustain life as well. Protection– With no atmosphere, our planet will be a rocky planet without any oceans, clouds or existence. This mixture of gases and types of conditions within the Earth’s atmosphere make existence possible. Plants and cre...

    Ozone is a molecule composed of three oxygen atoms, (O3). Ozone in the upper atmosphere absorbs high-energy ultraviolet (UV) radiation coming from the Sun. This protects living things on Earth’s surface from the Sun’s most harmful rays. Without ozone for protection, only the simplest life forms would be able to live on Earth. Indispensable for Life...

  4. Feb 24, 2012 · Earth's atmosphere, along with the abundant liquid water at Earth's surface, are the keys to our planet's unique place in the solar system. Much of what makes Earth exceptional depends on the atmosphere. For example, all living things need some of the gases in air for life support.

  5. Feb 23, 2019 · Our atmosphere protects the Earth from the harsh rays of the sun and reduces temperature extremes, acting like a duvet wrapped around the planet. Meanwhile, the greenhouse effect means that energy...

  6. Atmosphere, the gas and aerosol envelope that extends from the ocean, land, and ice-covered surface of a planet outward into space. The density of the atmosphere decreases outward, because the planet’s gravitational attraction, which pulls the gases and aerosols inward, is greatest close to the surface.
