What is the green house effect ?
Earth is a comfortable place for living thing . Its just the temperature plant and animals including human can alive. Why earth is so special ? One reason is greenhouse effect .
Greenhouse is a building of glass wall and the glass roof. The clear glass allows to sunlight to shine into the greenhouse . and also trap in sun heat inside. This is how keep plant warm even the night in the winter.
The greenhouse effect keep earth warm in pretty much same way. Earth is not surrounded by the glass. But it is surrounded by the jacket of gasses called it atmosphere.
In the daytime sunshine through the atmosphere warming earth surface. After the sun goes down earth surface cooled . this realeases heat back into the air. But some of heat trapped by gases in the atmosphere. These heat traping gases are called heat traping gases. Carbon-di-oxide, water vapour , methane are all example of greenhouse gases.
Earth need the balace the greenhouse gases to maintain just right the temperature for living things. But some human activity are changing earth natural greenhouse effect. For example burning fossil fuel like coal and oil release more carbon-di-oxide into our atmosphere . these extra greenhouse gases can cause the atmosphere to trap more and more heat leading to warmer earth .
NASA sattalite are constantly measuring these gases in our atmosphere to safe us. They have observed increase the amount of carbon-di-oxide and other greenhouse gases.the information of the NASA satellite can help scientist figure out where greenhouse gases are coming from ? and how they are adding in our atmosphere. These information help us to better understand the impact the greenhouse gases have in our climate. And help us better understand these very greenhouse that we call home .
Why temperature rising in our atmosphere day by day ?
There are six step cause rising temperature .
Step 1 : sunlight reaches the earth atmosphere . after arriving the sunlight some of its reflected to the space.
Step 2 : The rest of the Sun’s energy absorbed by earth surface. Its heated our earth.
Step 3 : in the night time heat release by the earth towards space.
Step 4: but some of heat trapped by our atmosphere . in other words some of the gases create a gas wall in our earth atmosphere . for this reason heat is trapped . these gases called as greenhouse gas . like carbon-di-oxide , methane. This is the natural process. These process help to grown lives in our earth.
Step 5 : the problem is found in step 5 . some of our activity like burning fossil fuels , agriculture relase more and more greenhouse gas .
Step 6 : which is the reason to extra heat trapped in our earth atmosphere. That’s why earth is more and more warm in day by day.
