Define atmosphere and atmospheric pressure
Answers
Explanation:
An atmosphere is a set of layers of gases present in our surrounding or other material body. These bodies are held in place by the gravity of that body. Atmospheric pressure is defined as force per unit area that is exterted by the weight of the air above that surface
✍ What is Atmosphere ?
The atmosphere is full of gases which surrounds Earth .
Question ;- What is atmosphere made of?
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 .
Question :- What are the types of 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 .
✍ Define Atmosphere Pressure
The pressure exerted by the earth's atmosphere at any given point, being the product of the mass of the atmospheric column of the unit area above the given point and of the gravitational acceleration at the given point .
In simple word , The pressure caused by the weight of the air above a given point .
