Would a spacecraft need as much fuel to escape from the moons gravity as it would to escape from the earths?
Escape velocity for the moon is a little over 5000 miles per hour. For the earth it is about 25,000 miles per hour. So the moon requires a fifth of the energy required to escape the earth.
How is earth atmosphere affected by solar energy?
The earth's atmosphere is affected by solar energy because the energy creates a greenhouse effect. When the radiation of the sun makes the earth too warm, there will be too much greenhouse gas that gets trapped in the atmosphere.
How much energy does the Earth receive from the sun everyday?
it gives off enough to light up the Earth for thirteen hours or more depending on daylight savings
How fast does a space shuttle travel in space in miles per hour?
It has to be going at least 17,500 miles per hour to overcome earth's gravity, so it's at least that much.

What is the benefit of earth hour?
Well I think that earth hour benefits our planet because we usually turn on the lights when we don't need them and just leave them on or we just turn on the t.vfor a bit watch a show then just leave it on so overall you are just wasting energy each day but because of earth hour we are making a better place for our planet so earth hour is very important and it is basically a routine because we do it every year and we save so much light that we don't waste at all so that is basically thebenefit of earth hour.

How much energy does Earth have?
A dice contains about 10^93 grams of energy. 93 grams of energy. Working something like that out is simple next to the size of the earth. It is difficult to say what the total energy of the earth is, because the earth gains mass every second from the sun: Not only that, but Approximately 120,000 TW (terrawatts), that is 120000000000000000 joules hits our earth every second. More energy hits the sun in one hour that the whole world uses in one year, which is 5.5 x 1024!! The earth must contain a tremendous amount, which i would guestimate at something like 10x1024,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
