Process in the Atmosphere

Solar Radiation:

Solar radiation is a radiation that radiates energy from the sun. But many people still don't know how the solar radiation works and the process of solar radiation. In this post I will explain to you about how solar radiation works and the process of solar radiation.


First There is a matter that is called a black body. It absorbs all the energy from the sun and turn it to radiation waves. From that we know that the energy that the sun transfer through space, when it comes to earth it turn into radiation throughout the black body.

Heating Earth Surface:

As we know Solar Radiation gives energy to earth. Then when it touches the earth surface it become hot. That's why the earth is hot, because of the radiation from the sun. Then the heat is transferred throughout the outer space. The process is that the sun/solar radiation go through the earth -> the earth absorbs the radiation -> when absorb the radiation turn to heat and the heat is transferred outer space. 

In this case we know that why the earth is hot. Did you know that the Green house traps the heat in the atmosphere so that the earth become even hotter. When the earth gets hotter is called the global warming. If the earth is too hot or too cold, the organism such as human beings can't live on the planet. So we need to give the same of heat to outer space as the sun radiates, that is called radiation balance.

Emission of outgoing infrared radiation:


As we know from the above that radiation comes from energy that sun gives to earth, when sun radiate the earth, it consists of energy that travel through the earth ground. The process is that the radiation that consist all that energy  was absorbed by the ground. The is a Black Body. Its converting it to infrared radiation that consist of energy that travels to outer space.

Water Cycle: 


We know that in the sky clouds are floating and moving around the earth. When the cloud turn gray it comes raining. But what makes a cloud and what makes rain. All that question will be answered in this post .


As we know that rain produce water. But that's just one of the process of creating water. The process that creates water is commonly called water cycle. From scientist we know that the water runs is a cycle and commonly called a Hydro logic cycle. Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over millions of years.


From the Graphic below we can imply that the water cycle process has a different process. A simple way to explain the water cycle process is first the water from the ocean and the seas and other water source will evaporates. The steam will gather together and make a cloud. The cloud soon got a lot of water vapor in it, the color of the cloud turns to a grayish color. Then the condensation process begins, when water vapors turn into water droplets that roams the earth. The rain can drop anywhere, at the mountain, lake and anywhere else.    From there there a different process so the water can evaporates again. 

From the mountain the water will freeze because of the low temperature. From there the water will either sublimate from snow and ice into steam, or it will get unfrozen by the sun's heat and go through a water stream that go to the ocean or water places and evaporates again.

From the lake the water will be contaminated, so that the water cannot travel through the ocean again. The water will evaporate from the lake or it will go into the soil, some of it will get absorbed by trees for photosynthesis and the rest will go to the ocean again. The process when the water travels through the soil to the ocean will be long.
