Question 1

Atmosphere

Answer 1

the whole mass of air that surrounds the earth. 2 : the gas surrounding a heavenly body (as a planet) The atmosphere of Mars is made up mostly of carbon dioxide. 3 : the air in a particular place. 4 : a surrounding influence or set of conditions an atmosphere of excitement.

Question 2

Altitude

Answer 2

Altitude or height is a distance measurement, usually in the vertical or “up” direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context.

Question 3

Density

Answer 3

Density is the number of things—which could be people, animals, plants, or objects—in a certain area. To calculate density, you divide the number of objects by the measurement of the area. The population density of a country is the number of people in that country divided by the area in square kilometers or miles.

Question 4

Troposphere

Answer 4

The troposphere is the first and lowest layer of the atmosphere of the Earth, and contains 75% of the total mass of the planetary atmosphere, 99% of the total mass of water vapour and aerosols, and is where most weather phenomena occur.

Question 5

Stratosphere

Answer 5

Above the troposphere and below the mesosphere, we have the stratosphere. “Surat” means layer. This layer of our atmosphere has its own set of layers. There are no storms or turbulence here to mix up the air, so cold, heavy air is at the bottom and warm, light air is at the top

Question 6

mesosphere

Answer 6

The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermostat. In the mesosphere, temperature decreases as altitude increases

Question 7

troposphere

Answer 7

The thermosphere is the layer in the Earth’s atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions; the thermosphere thus constitutes the larger part of the ionosphere.

Question 8

Stratosphere

Answer 8

The stratosphere is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere

Question 9

Mesosphere

Answer 9

The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.

Question 10

thermosphere

Answer 10

The thermosphere is the layer in the Earth’s atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions; the thermosphere thus constitutes the larger part of the ionosphere

Question 11

Exosphere

Answer 11

The exosphere is a thin, atmosphere-like volume surrounding a planet or natural satellite where molecules are gravitationally bound to that body, but where the density is so low that the molecules are essentially collisionless

Question 12

Temperature

Answer 12

Temperature is a physical quantity that expresses the hotness of matter or radiation. There are three types of temperature scale: those, such as the SI scale, that are defined in terms of the average .

Question 13

Nitrogen
