What is atmosphere in 7th?
(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 less quantities. All living beings on earth depend on the atmosphere for their survival.
What is the 5th layer of the atmosphere?
There is a fifth layer called the exosphere, where the atmosphere gradually thins and merges with interplanetary space, but we won't consider this further as the molecules are so far apart, it no longer behaves like a gas.
Is the exosphere the 5th layer?
Layer 5: Exosphere
The fifth layer of the atmosphere, or outmost layer, is called the exosphere. This layer is between approximately 600 km to 10,000 km above the surface. This layer contains the fewest molecules within the Earth's atmosphere. From the exosphere, molecules can escape into outer space.
What are the five layers of the atmosphere in 6th?
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 is the fifth layer of the atmosphere and what is its temperature?
Hydrogen and helium gases predominate in this outermost region. At the outermost boundary of our atmosphere, the kinetic temperature may reach a fantastically high value of about 5568 degree Celsius. However, this temperature in its real sense is entirely different from the temperature at the earth's surface.
What are the 6 parts of the atmosphere?
Earth's atmosphere has a layered structure. From the ground toward the sky, the layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Another layer, called the ionosphere, extends from the mesosphere to the exosphere. Beyond the exosphere is outer space.Nov 7, 2022
What is the 7 atmosphere?
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 components of the atmosphere?
These gases are found in atmospheric layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.May 19, 2022
