Which of the following gases absorbs ultra violet rays?
It is found between 10 and 50 Km above the surface of the earth and acts as a filter.
The uppermost layer of the atmosphere is
The exosphere is the uppermost layer of the atmosphere. Together with the ionosphere, it makes up the thermosphere. The exosphere extends to 10,000 km above the Earth's surface. This is the upper limit of our atmosphere. The atmosphere here merges into space in the extremely thin air.
It is an element of atmosphere
Pressure is an important element of atmosphere.
Which gas is opaque to the outgoing terrestrial radiation?
It is responsible for green house effect.
Excess carbon dioxide in the atmosphere due to pollution will cause
The remaining trace gases include the greenhouse gases, carbon dioxide, methane, nitrous oxide, water vapour and ozone, so-called because they are involved in the Earth natural greenhouse effect, which keeps the planet warmer than it would be without an atmosphere.
Sea salt, pollen, ash, smoke, soot, fine soil, these all are associated with __________
All of these are dust particles, which are also present in the atmosphere.
The radiations that heat earth’s atmosphere, comes from the
Our atmosphere is heated up by the radiations reflected back from the earth's surface.
Once in the Earth's atmosphere, clouds and the surface absorb the solar energy. The ground heats up and re-emits energy as longwave radiation in the form of infrared rays. Earth emits longwave radiation because Earth is cooler than the sun and has less energy available to give off.
Increase in the volume of carbon dioxide for the past few decades is mainly due to
The burning of fossil fuels produces around 21.3 billion tons of carbon dioxide (CO2) per year and it is estimated that natural processes can absorb only half of this amount. Therefore, the net increase of CO2 per year is around 10.65 billion tons.
Which one of the following gases constitute the major portion of atmosphere?
The most abundant gas in our atmosphere is Nitrogen. It constitutes about 78% of our atmosphere.
Earth absorbs more
Earth absorbs more heat then it loses.
