How much greater is the angular momentum of the Earth orbiting about the sun than the moon orbiting about the Earth?

Assuming a circular orbit for simplicity, the magnitude of the angular momentum is rmv - that is, the radius of the orbit times the mass times the velocity. I'll leave the details of the calculations to you; basically you have to look up:
- Earth's, or the Moon's, orbital radius (the distance from Sun to Earth vs. the distance from Earth to the Moon);
- The mass of the orbiting object;
- Its velocity in orbit.
Then you must divide one by the other, since I assume it's the ratio you are interested in.

The angular momentum of the earth is constant?
More or less. There is a law of conservation of angular momentum, according to which Earth can't gain or lose angular momentum on its own - if for example it loses angular momentum, it has to go somewhere. A meteor who falls into the Earth, or a rocket leaving the Earth can change Earth's angular momentum - but the total angular momentum (e.g., of the system meteor + Earth) is the same, before and after the impact.
Why the earth was revolving?
Conservation of angular momentum.
What is Earth's angular momentum when it is at perihelion in its orbit?
The point at which Earth is closest to the the Sun is called perihelion. Even though Earth is close to the Sun then, the Northern hemisphere experiences winter then. This is because the Northern Hemisphere is tilted away from the Sun at perihelion.
How does the moon slow Earth's rotation and how does the Earth change the moon's orbit?
The Earth-Moon gravitational interaction that produces the tides is gradually slowing the Earth's rotation. So, the Earth loses angular momentum. That causes the Moon to gain angular momentum. The acceleration of the Moon causes its orbit to slowly get larger. See "related links" below. In the link, look for the headings "Tidal Braking of the Earth" and "Lunar Recession".
Which physical quantity is conserved of an earth satellite?
Velocity of satellite and hence its linear momentum changes continuously due to the change in the direction of motion in a circular orbit. However, angular momentum is conserved as no external torque acts on the satellite.

How angular momentum of the earth remain constant?
As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum
Why the earth was revolving?
Conservation of angular momentum.
What makes the earth to rotate around the orbit?
The Earth condensed out of a rotating Solar Nebula, inheriting its angular momentum for the condensing cloud. The conservation of angular momentum allows the Earth to maintain its orbit.
Why does earth rotate constantly?
Actually it doesn't - but the changes are quite small. There is a physical law called Conservation of Angular Momentum - the total angular momentum (informally, we might say the "amount of rotation") can't increase or decrease in a closed system. If the distribution of masses on Earth changes, Earth's angular velocity can change - but any redistribution of masses is rather small-scale, compared to the size of the Earth. On the other hand, Earth rotates slower and slower over time - angular momentum is transferred to the Moon in this case.
What does the earth spins on?
the earth spins on an axis, which is carried over by conservation of angular momentum when the earth was created
Which force acts for the revolution of the earth in its own axis?
no force, just angular momentum which is conserved.

What is the resource that powers wind?
Almost all is from the sun, with a very small contribution from Earth's angular momentum.
Why does the earth spin in space?
The Earth spins in space due to an action called angular momentum. The Sun is considered the fixed point of the Earth, which is why the Earth rotates around the Sun.
Why Saturn has a completed day in just ten earth hours?
It just has a massive amount of angular momentum, like Jupiter.
