What is atmosphere one word answer?
An atmosphere is a layer or a set of layers of gases surrounding a planet . An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low. The atmosphere can be divided into layers based on its temperature.
What is called the atmosphere?
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.
What are the 5 types of atmosphere?
Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere . Troposphere.

the atmosphere help us to protect from the harmful rays of the sun . the earth atmosphere contains water oxygen and carbon dioxide. life on Earth needs the atmosphere. the atmosphere of earth stop the rays which can cause eye problems and skin cancer.
What is the general concept of atmosphere?
Atmosphere refers to the gases surrounding a star or planetary body held in place by gravity . ... The composition of the Earth’s atmosphere is about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, with water vapor, carbon dioxide, and other gases. The atmospheres of other planets have a different composition.
What is the greenhouse effect in a sentence?
The greenhouse effect could lead to global warming or, at least, climate change . This layer of gases warms a planet by trapping the sun’s heat, a process called the greenhouse effect. Without the greenhouse effect, the earth would be a dead, frozen world.

What are the characteristics of atmosphere?
Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure .
Why is the atmosphere important for humans?
The atmosphere protects us from UV and other short wavelength light that would otherwise do a lot of damage to the DNA of living organisms. ... The atmosphere is also important because it contains oxygen , which we and other living organisms breathe.
What is the hottest layer of the atmosphere?
The 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).
