half the area of the earth (times...?) the area of the earth minus the area of the sun. 1/2 x 4/3 x pi x radius of earth squared) minus 4/3 x pi x radius of sun squared ---- I figured it a little differently... All the energy radiating from the Sun will pass through a sphere the size of the Earth's orbit, which, as we all learned in grammar school, is roughly 93 million miles. So, the area of that sphere is 4 times pi times 93 million squared, roughly 1017, or one hundred million billion square miles.
You could say the amount hitting the Earth is what hits a disc whose area is that of a circle the radius of the Earth; if the Earth's diameter is about 8000 miles, another factoid from grammar school, that makes the disc area about 50 million square miles.
The ratio of these areas gives the fraction of the Sun's radiation striking the Earth. Do the math, and you get 5x10-10 or about 5 ten-billionths!
On a hot summer's day, you can appreciate that we don't get all the Sun's radiant energy or else we'd need sunblock with SPF 250,000,000,000.
What else can I help you with?
Earth receive heat from sun is called.?
The process that Earth receives heat from the sun is called radiation.
Does the sun keep the earth warm?
The sun warms the earth. The heat (energy) from the earth then heats the air.
What is the celestial body of gas an emits light?
sun
What would it do if earth didn't have a sun?
The Earth Would Freeze becuase the Sun is the Earth's Light and Heat source.
What heat warms the surface of the earth?
the sun
What does the sun give us here on Earth?
The sun gives energy, in the form of heat and light.
What does sun give us?
The Sun is a huge star that is seen during the day on Earth. It gives the Earth many things, it give energy, vitamins, heat and helps things live.
Will the sun always give off as much heat as it is now?
yes
How does heat travel from the sun to earth?
Heat from the sun transfers to Earth through radiation.
When does the earth receive less heat from the sun?
when earth absorbs the heat coming from the sunthere is too much moisture in the air3.when the clouds reflect the heat back to the space
What 2 types of energy does the sun give to the earth?
Radioactive and solar energy (or light and heat).
Explain How you can feel heat from the sun even though the sun is millions of miles away in space?
The distance in between the Earth and the Sun is 93000000 miles. In space the temperature in the sun is 10 times that on Earth. The sun produces such incredible heat energy that it is able to reach Earth. The heat is much less here than it would be if we were closer to the sun. The sun creates its heat by burning the gasses that make it up.
Does the sun give heat to every planet?
Yes it does but the planets closer to the sun get more heat and the planets that are farther away get less heat. That is why Venus is hotter than our Earth and Mars is colder.
How much heat does the sun give off?
The sun emits 1.2×1034 J each year.
How does the sun heat parts of the earth that do not receive much direct sunlight?
Because the rays of the sun is so hot it will heat any part of the earth witout being hit my direct sunlight
Earth receive heat from sun is called.?
The process that Earth receives heat from the sun is called radiation.
Where does lava's heat come from?
Lava is created/stored at the center of the earth. The center of the earth is very warm because the earth absorbs some( i believe 5%) of the heat give off by the sun.
