what is the fifth layer of the atmosphere?

Exosphere. The transition zone between the Earth's atmosphere and space. You can find artificial satellites here

how does the atmosphere protect us?

it absorbs the sun's heat and helps keep the earth's temperature warm and fairy stable. 

it filters out solar radiation that is harmful to living things

what is weather?

is is a state of atmosphere at a certain time and place

200

what is the fourth layer of the atmosphere?

thermosphere. there is very little air and it can be very hot. Many meteorites disintegrate here. this is where we can see the aurora borealis

200

what is air pollution?

air pollution contaminates the atmosphere with gases that harm peoples health. 
200

where layer does weather take place in the atmosphere?

in troposphere, the layer of the atmosphere closest to the earth. 

300

what is the third layer of the atmosphere ?

mesosphere. There is very little air in this layer. We can see shooting stars and there is sometimes turbulence here. Spaceships returning to earth. start to feel the friction of the atmosphere here.

what is the ozone layer? What is happening to the ozone layer?

the ozone layer stops most ultraviolet rays from reaching the earth. because of air pollution the ozone layer is decreasing and more ultraviolet rays are reaching us, damaging the health of living things and the planet.

what determines the temperature of the air?
temperature of the air depends on the solar radiation it receives and we express it in degrees Celsius. 
400

what is the second layer of the atmosphere?

stratosphere. the air forms horizontal layers or strata here. It contains the ozone layers, which absorbs most of the Sun's harmful rays. 

400

how many layers does the atmosphere have?

5

What is hot air?

when the air is hot we say that the temperature is high, for example 30 o C in summer.
500

what is the first layer of the atmosphere?

troposphere. water vapor and most of the oxygen we breathe is in this layer. we can find clouds, rain and wind here. 

500

what is the atmosphere?

the atmosphere is a layer of air that covers the earth. it is 1000 kilometers thick. it is mainly composed of nitrogen, oxygen, water vapor and other gases in very small amounts.

what is cold air?

when the air is cold we say cold air. we say that the temperature is low. below 0 o C , rain turns to snow and we indicate these temperatures with a minus sign.
