Hey, have you felt how hot is has been lately? I've been having to stay out of the sun and I've been spending more time in the trees.
Hi! I know it's been so hot! I literally have had to go under leaves to get the shade.
Did you know that the sun is mainly made of hydrogen and helium. Inside of the sun, hydrogen and helium are converted into energy because of thermonuclear fusion reaction.
Oh really. But did you know that the energy created is called thermal energy and it raises the temperature of the sun. The level of the heat is about twenty times larger than the Earth's surface. The heat travels through space and it enables the transfer of heat which is radiation.
Another cool fact is that electromagnetic waves are self-propagating of electric and magnetic fields. These waves move energy through space and they affect regions far from the origin of where it happened.
Oh yeah, they also include radio waves, infrared, visible light, X-rays, and gamma rays.
One of my friends told me about the greenhouse effect. Do you know anything about it?
Well the temperature of Earth is very lower than what we experience. The greenhouse effect is the difference in the effect of the heat absorbing components on our atmosphere.
The earth contains many trace components. Nitrogen and oxygen don't absorb much radiation but some of the minor components absorb more. One of them is water vapor which absorbs lots of heat.
Oh I'm starting to remember now. So since the atmosphere is basically transparent to sunlight, all of the light that is absorbed by the atmosphere can't be released into space because of absorption in the atmosphere by trace gases.
