The solar flux is 1350 watts per square metre, and the Earth intercepts a
circular area of pi x r2 square metres with the radius r in metres. The radius
is 6,378,000 metres therefore the total power intercepted is 1.7 x 1017 watts,
which is something like 25 Megawatts for every man, woman and child on Earth.

How much of earth is in sunlight when a autumnal equinox occurs?
Half of Earth is illuminated by the sun at all times.
How does the sun position in relation to the earth correspond to our seasons?
It's not so much the Sun that changes; rather, Earth's axis is tilted (with respect to a perpendicular to Earth's plane of orbit). As a result, when Earth is on one side of the Sun, the northern hemisphere gets more sunlight; when Earth is on the other side of the Sun, it is the southern hemisphere that gets more sunlight.
What is the differences between a solar eclipse and a lunar eclipse?
a solar eclipse is where the earth blocks the sunlight to the moon (sun--earth--moon) a lunar eclipse is where the moon blocks the sunlight to the earth (sun--moon--earth)

How does the light from the sun warm the earth?
The sunlight is partially absorbed by materials on Earth; when that happens, the energy in the sunlight is converted into heat energy.
How much of earth is in sunlight when a autumnal equinox occurs?
Half of Earth is illuminated by the sun at all times.
How much more sunlight on Mars than on Earth?
Mars gets LESS sunlight than Earth does, because of its greater distance from the Sun.
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
Why do the number of hours of sunlight change as the earth revolves around the sun?
The number of hours of sunlight changes as the earth revolves around the sun because the earth revolves around the sun tilted. Depending on the position of the earth in relation to the sun will determine the number of hours of sunlight emitted towards earth.

How does radiation warm the earth?
By the sunlight, when the sunlight enter in the earth
Earth is closest to the sun in JanuaryWhat effect does this have on seasons?
Not much. The seasons are driven primarily by how much direct sunlight the Earth receives at a given latitude.
What is Jupiter's amount of sunlight?
Jupiter is the fifth planet from the Sun and is the largest in the Solar System. It receives around 1/27 as much sunlight as Earth.
How do you explain how the phases of the moon are caused by the revolution of the moon around the earth and the position of the sun?
the phases of the y how much sunlight the moon is moon are caused by how much sunlight the moon is reflecting
What is one energy the reaches earth from the sun?
The energy that reaches the Earth from the sun is known as sunlight.
What is the differences between a solar eclipse and a lunar eclipse?
a solar eclipse is where the earth blocks the sunlight to the moon (sun--earth--moon) a lunar eclipse is where the moon blocks the sunlight to the earth (sun--moon--earth)
When the sun the moon and earth are in a straight line would an eclipse of the sun occur?
Yes, a solar eclipse is when the moon passes in front of the earth (between the earth and sun) blocking sunlight. A lunar eclipse is when the earth is in between the sun and moon, and prevents the moon from reflecting sunlight and "shining"
