What Is The Characteristic Of The Atmosphere?

What are the 3 main properties of the atmosphere?

Identify the three properties of the atmosphere and describe how they vary with height in the atmosphere.

The three properties of the atmosphere are temperature, air pressure, and humidity.

Air pressure decreases with height because the mass of air above you decreases..

What is the atmosphere described as?

Essentially, the atmosphere is is a collection of gases that makes the Earth habitable. The atmosphere consists of 78% nitrogen, 21% oxygen, 1% water vapor, and a minute amount of other trace gases like argon, and carbon monoxide.

What are 3 facts about the atmosphere?

The atmosphere layer closest to the earth is referred to as the troposphere. Beyond the troposphere are the stratosphere, the ozone layer, the mesosphere, and the thermosphere. The atmosphere is made up of 78% nitrogen, 21% oxygen, and smaller amounts of argon, carbon dioxide, helium, and neon.

What is the important of atmosphere?

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.

What atmosphere do we live in?

TroposphereThe Troposphere This is the lowest part of the atmosphere – the part we live in. It contains most of our weather – clouds, rain, snow. In this part of the atmosphere the temperature gets colder as the distance above the earth increases, by about 6.5°C per kilometre.

What is the importance of atmosphere?

Many living things, including humans, need oxygen to breathe. The gases in the atmosphere also protect us from harmful solar rays, but not completely, which is why we often wear sunscreen. The gases trap heat, which the earth naturally produces. Without an atmosphere, the surface of the earth would be very, very cold.

What are the 7 layers of atmosphere?

Earth’s Atmospheric LayersTroposphere. The troposphere starts at the Earth’s surface and extends 8 to 14.5 kilometers high (5 to 9 miles). … Stratosphere. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. … Mesosphere. … Thermosphere. … Ionosphere. … Exosphere. … Credit: NASA/Goddard.

What is the hottest layer of the atmosphere?

thermosphereThe thermosphere is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24).

What are two characteristics of the atmosphere?

In addition to containing nitrogen and oxygen, the atmosphere contains small particles, such as dust, volcanic ash, sea salt, dirt, and smoke. The next time you turn off the lights at night, shine a flashlight, and you will see some of these tiny particles floating in the air. Water is also found in the atmosphere.

What are examples of the atmosphere?

Atmosphere is defined as the area of air and gas enveloping objects in space, like stars and planets, or the air around any location. An example of atmosphere is the ozone and other layers which make up the Earth’s sky as we see it. An example of atmosphere is the air and gases contained inside a greenhouse.

What is unique about Earth’s atmosphere?

Earth is the only planet in the solar system with an atmosphere that can sustain life. The blanket of gases not only contains the air that we breathe but also protects us from the blasts of heat and radiation emanating from the sun. It warms the planet by day and cools it at night.
