What is atmosphere with diagram?
An atmosphere can be defined as the blanket of gas on the surface of a planet. The Earth’s atmosphere is the mixture of gases that surrounds the planet. The Earth’s atmosphere contains mainly 5 layers which are troposphere, stratosphere, mesosphere, thermosphere and exosphere. 1.

What is atmosphere for 7th grade?
(i) What is the atmosphere? Answer: The blanket of air surrounding the earth is called the atmosphere. The atmosphere primarily comprises nitrogen and oxygen in bulk and other gases like carbon dioxide, helium, ozone, etc in lesser quantities.
What is structure of 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 atmosphere explain?
An atmosphere is the layers of gases surrounding a planet or other celestial body. Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
What are examples of 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.
How do you remember the 5 layers of the atmosphere?
From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. “The Snow Makes Things Exciting” is an easy way to remember these layers in order.
Which is the hottest layer?
The inner core is the hottest layer, above 9000 Fahrenheit and it is 1250 km thick! Crust: The Earth’s thinnest layer!
What is a simple definition of atmosphere?
What are the main features of the atmosphere?
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.
What is atmosphere detail?
What is the main purpose of the atmosphere?
Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.
What is importance of atmosphere?
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.
What are the 3 main properties of the atmosphere?
There are three factors which affect the properties of the atmosphere: temperature, density and pressure.
What is the easiest way to remember the layers of the atmosphere?

How do you teach the layers of the atmosphere?
The Atmosphere for kids – Layers of the Earth – Science for Kids – YouTube
What layer is totally liquid?
The outer core
The outer core is the liquid largely iron layer of the earth that lies below the mantle. Geologists have confirmed that the outer core is liquid due to seismic surveys of Earth’s interior.
Which part of Earth is cold?
Earth’s poles are the coldest places on the planet, with the South Pole outpacing the North Pole in terms of bone-chilling weather. The lowest temperature ever recorded was in Antarctica, about 700 miles (1,127 kilometers) from the South Pole.
What are 5 examples of the atmosphere?
Earth’s atmosphere consists of five main layers from lowest to highest: troposphere, stratosphere, mesosphere, thermosphere and exosphere.
- The five main layers of the Earths atmosphere. (
- The Sahara Desert in northern Africa has a hot, dry climate.
- Earth’s atmosphere is a thin band of air composed of five main layers. (
What are the 3 functions of 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.
What would happen if the atmosphere disappeared?
If you sucked away the entire atmosphere, most higher vertebrates (including humans) would asphyxiate in seconds. Other land animals would follow within a few minutes, plants within a few hours. Meanwhile, the sudden drop in pressure would have a curious effect on the seas.
What are the main characteristics of the atmosphere?
What is the general concept of atmosphere?
What is the main function of the atmosphere?
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.
In which layer does almost all the weather occur?
Troposphere
Troposphere. Known as the lower atmosphere almost all weather occurs in this region. The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20 km) high. The height of the troposphere varies from the equator to the poles.
