The atmosphere is only form by gases.
In the gaseous state, the particles move in all directions and occupy all the available space.
In the gaseous state, it has an unfixed mass, variable volume and variable shape.
What is Atmosphere's composition?
Nitrogen, oxygen and ozone.
Nitrogen, carbon, oil and oxygen.
Nitrogen, oxygen, water vapour, ozone and inert gases.
Nitrogen, argon, oxygen, carbon and water vapour.
The atmosphere is completely homogeneous because the gases in it are arranged according to their density.
The less dense gases are closer to the Surface while the deser gases are further away.
The structure of the atmosphere is static.
TROPOSPHERE
Until 20 km.
It contains 80% of the total mass of atmospheric gases.
The temperature decrease with altitude.
STRATOSPHERE
The gases that form it move vertically.
The ozone layer (25 km).
12 km to 60 km
MESOSPHERE
This is where shooting stars are formed.
50 km to 85 km
The temperature descend to -200ºC.
TERMOSPHERE
80 km to 1.500 km
It absorbs the strongest and most energetic solar radiation.
The temperature in the upper part reaches 10.000ºC.
EXOSPHERE
1.000 km until the space.
It has a very high concentration of gases.
Artificial satellites are located here.
What is the double function on the Atmosphere?
The regulatory action of the Earth's water propotion and protective action.
The regulatory action of the Earth's temperature and nonprotective action.
The regulatory action of the Earth's temperature adn protective action.
The atmospheric gases and life. What is the correct answer?
Carbon dioxide, oxygen adn water vapour.
Oxygen, carbon, nitrogen and coal.
Water vapour, nitrogen, oxygen and carbon dioxide.
Air pollution is the alteration og the normal composition of air.
Types of pollutants. Choose the correct answer.
Natural and artificial.
Chemical and natural.
Physical and chemical.
Natural pollutants. They are generated by natural phenomena, with human intervention.
Artificial pollutants. They are generated by human activity.
Choose the correct answer about physical pollutants.
Electromagnetic, industrial activities and noise.
Electromagnetic, radiation and noise.
Electromagnetic, radiation and transport.
Choose the correct answer about consequences of air pollution.
Acid rain, destroy of natural habitats and respiratory problems.
Acid rain, maintenance of natural habitats and insomnia.
Headaches, acid rain adn vegetation grow.
Choose the correct answer about GLOBAL measures to reduce pollution.
Reduce energy comsumption, clean and purify.
Clean and purify, control and reduce emissions, and encourage reforestation.
Clean and purify, and reduce the amount of residues and rubbish.
The greenhouse effect is the phenomena by which atmosphere retains some of the heat from the Sun.
The causes of greenhouse effect are burning fossils fuels and destruction of forest.
Choose the most complete answer about consequences of the increase in the greenhouse effect.
The glaciers to melt, be more torrential rains and increase of allergies.
The glaciers to melt, be more acid rain and non disappearance of ecosystems.
The glaciers to melt, decrease of allergies and disappearance of ecosystems.
The atmosphere acts as a filter that protects us from good solar radiation and the impact of meteorites.
X-RAYS and GAMMA RAYS are absorbed by the mesosphere and the termosphere.
Choose the correct answer about ULTRAVIOLET RAYS.
UVA RAYS are absorbed by the ozone layer.
UVC RAYS aren't absorbed by the ozone layer.
UVB RAYS are nearly absorbed by the ozone layer.
Some consequences of destroying the ozone layer are skin cancer, deteriorate of the immune system and preamure catarats.
