Mesosphere

The lower layer of the atmosphere that immediately surrounds the Earth is called the troposphere. Stratospheric ozone is a naturally-occurring gas that filters the sun’s ultraviolet (UV) radiation. This is typically regarded as ‘good’ ozone since it reduces the harmful effects of ultraviolet (UV-B) radiation.

the stratosphere

Ozone (O3) is mainly found in two layers of our atmosphere: the troposphere and the stratosphere. The stratosphere, 10 and 50 kilometers above the Earth’s surface, contains around 90% of the total atmospheric ozone amount.

Ninety percent of the ozone in the atmosphere sits in the stratosphere, the layer of atmosphere between about 10 and 50 kilometers altitude. The natural level of ozone in the stratosphere is a result of a balance between sunlight that creates ozone and chemical reactions that destroy it.

The mesosphere a layer extending from approximately 30 to 50 miles (50 to 85 km) above the surface, is characterized by decreasing temperatures. The coldest temperatures in Earth’s atmosphere occur at the top of this layer, the mesopause, especially in the summer near the pole.

Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.

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.

thermosphere

10,000 kilometers

The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth’s surface is called the exosphere.

Life on Earth would be impossible in the absence of the atmosphere – the thin layer of gas that envelops our globe, writes William Reville.

It is very essential for life on earth. Complete Answer: The atmosphere contains the air that we breathe; protects us from the harmful radiation of the Sun; helps to keep the planet’s heat on the surface, and plays a very important role in the water cycle.

Answer 1: The atmosphere is important for many reasons! One reason is that the earth’s atmosphere acts as an insulating layer that protects the earth’s surface from the intense light and heat of the sun. The atmosphere is also important because it contains oxygen, which we and other living organisms breathe.

• protects us from the sun.
• protects from metors.
• gives us oxygen and protein.
• allows us to stay alive.

The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth’s surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation …

Atmosphere is essential for life on Earth as it supplies oxygen, water, CO2 and some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation.

The atmosphere has some very important functions: It has the oxygen that we need to breathe. The atmosphere filters the Sun’s rays. If there were no atmosphere, the Sun would burn us more.

Answer. Atmosphere doesn’t controlled the weather,atmosphere doesn’t control the day and night time and atmosphere doesn’t control the ecosystem.

What are the advantages of atmosphere for earth and living things…

• Protects all living things and the earth from dangerous radiation that is from the sun.
• The atmosphere keeps us warm.
• The atmosphere gives us weather like wind, rain, and snow.
• Protects us from objects that are coming to earth from outer space.

1) The troposphere is the first layer above the surface and contains half of the Earth’s atmosphere. Weather occurs in this layer. 2) Many jet aircrafts fly in the stratosphere because it is very stable. Also, the ozone layer absorbs harmful rays from the Sun.
