What protects the Earth from extreme temperature?
The atmosphere
The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.
Is Earth too hot or too cold?
Earth is the only planet we know of that can support life. The planet is not too close or too far away from the sun. It lies in a “Goldilocks zone” that is just right — not too hot, not too cold. The distance from Earth to the sun is one of the most important factors in making Earth habitable.
What is the protective shield for life on Earth?
ozone
Earth is surrounded by invisible gases that form a thin protective blanket that we call the atmosphere. It contains the oxygen that we breath as well as other important gases such as nitrogen, carbon dioxide, water vapor, and ozone.
What works as a shield of earth to protect it from harmful rays of the Sun?
The ozone layer
The ozone layer is a region of high ozone concentration in the stratosphere, 15 to 35 kilometres above Earth’s surface. The ozone layer acts as an invisible shield and protects us from harmful ultraviolet (UV) radiation from the sun.
How does the atmosphere prevent us from getting too hot during the day?
The atmosphere protects Earth like a big blanket of insulation. It absorbs the heat from the Sun and keeps the heat inside the atmosphere helping the Earth to stay warm, called the Greenhouse Effect. It also keeps the overall temperature of the Earth fairly steady, especially between night and day.
Why is our planet that too hot not too cold?
The earth has conditions that support life. It is neither too hot nor too cold. The presence of oxygen in the air in appropriate proportion supports life. These factors make the earth a unique planet.
What protects space Earth?
Earth’s magnetic shield protects us from the cosmic radiation and is strongest at the equator and weakest near the poles. The magnetic shield diverts most of the radiation around the earth. Earth’s atmosphere shields us from most of the remaining radiation that travels to Earth.
What is the protective bubble around the Earth called?
magnetosphere
Earth, a giant magnet Earth’s magnetic field extends thousands of kilometers outward into space forming a gigantic “magnetic bubble” known as the magnetosphere. The magnetosphere shields Earth from most particle radiation originating from the Sun as well as most cosmic radiation.
