why atmosphere stays on earth?

Fortunately for us, Earth's gravity is strong enough to hold onto its atmosphere. Mars, for example, is less than half Earth's size and around one-tenth Earth's mass. Less mass means less gravitational pull. ... That means, the air nearer Earth's surface is squished by the air above it, and is thus denser.

Moderates Earth's Temperature Along with the oceans, the atmosphere keeps Earth's temperatures within an acceptable range. Greenhouse gases trap heat in the atmosphere so they help to moderate global temperatures. ... Important greenhouse gases include carbon dioxide, methane, water vapor, and ozone.

The atmosphere is most dynamic in nature because it holds gases and harmful rays to protect the earth to make weather. Hope this answer will be helpful to u...!!! The reason is this that it holds gasses and harmful rays to protect the earth to make weather.

If Earth had no atmosphere, apart from having no air to breathe, the surface of the Earth would be 0 degrees Fahrenheit. ... The atmosphere contains the warmth we all need to survive, the oxygen we all breathe, and carries the rain we all need. Without our atmosphere life as we know it would cease to exist.

It's a good thing these gases are there. Our atmosphere protects the Earth from the harsh rays of the sun and reduces temperature extremes, acting like a duvet wrapped around the planet.

An atmosphere (from Ancient Greek ἀτμός (atmos), meaning 'vapour', and σφαῖρα (sphaira), meaning 'ball' or 'sphere') is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body.

Air has molecules that are constantly moving. Because air has mass, Earth's gravity attracts it and gives it weight. Because it has weight, and the air molecules are constantly bumping into things, it exerts pressure.

We are also protected by the atmosphere. ... (Without the atmosphere, the average temperature on Earth would be below freezing!) The atmosphere also protects living things on Earth from the sun's harmful ultraviolet radiation. A thin layer of gas called ozone high up in the atmosphere filters out these dangerous rays.

The primary reason that the atmosphere is deepest and thickest at the equator is because the air is, on average, warmer there than anywhere else on Earth. Warm air is less dense than cold air. And gravity exerts equal pressure worldwide, so atmospheric pressure is the same worldwide, weather systems aside.

Earth's atmosphere is similar to a jacket for our planet. 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.

The atmosphere of Earth is the layer of gases, commonly known as air, retained by Earth's gravity, surrounding the planet Earth and forming its planetary atmosphere. ... The Kármán line, at 100 km (62 mi), or 1.57% of Earth's radius, is often used as the border between the atmosphere and outer space.

The atmosphere is a protective layer of gasses that shelters all life on Earth, keeping temperatures within a relatively small range and blocking out harmful rays of sunlight. The atmosphere has five different layers that are determined by the changes in temperature that happen with increasing altitude.

Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace amounts of other gases, and water vapor. This mixture of gases is commonly known as air.

The atmosphere is a thin layer of gases that surrounds the Earth. It seals the planet and protects us from the vacuum of space. It protects us from electromagnetic radiation given off by the Sun and small objects flying through space such as meteoroids.

An atmosphere is the layer of gases that envelop a planet. On the Earth, it is this envelope that allows organisms to live. Atmospheric ozone protects us from ultraviolet radiation. CO2 and other gases trap heat and keep the surface warm enough for life to thrive.

Earth has plentiful liquid water for life. The Oxygen in the atmosphere forms ozone which blocks out the harmful UV radiation which would make life on land impossible. Earth has plate tectonics which recycles elements essential for life.

The troposphere gets its heat from the ground, and so temperature decreases with altitude. Warm air rises and cool air sinks and so the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun's harmful UV.
