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 earths angular momentum when it is nearest to the sun is greater then when it is farthest from the sun?
This statement is incorrect. Earth's angular momentum remains constant throughout its orbit around the Sun. Although Earth moves faster when it is closer to the Sun due to Kepler's second law of planetary motion, this is balanced by its greater distance from the Sun when it is farthest, resulting in a constant angular momentum.
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.
Does angular momentum of a planet depend on its mass and distance from the sun?
Of course! The mass controls its speed, momentum, and how it tilts as its rotation around the sun continues. As a planet rotates on its axis, it will tilt at the sun, which is a big gravity machine. The earth is believe to be tilted because of collisions that are believed to have taken place billions of years ago. The earth collided with other proto planets in space, and became tilted. - pianodriver
What is Earth's angular momentum when it is at perihelion in its orbit?
Earth's angular momentum remains constant throughout its orbit around the Sun due to the conservation of angular momentum. The angular momentum at perihelion (closest point to the Sun) is the same as at any other point in its orbit.

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

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.

What is the significance of the angular momentum of Earth about its axis in relation to its rotational motion and stability?
The angular momentum of Earth about its axis is important for its rotational motion and stability. It helps to maintain the planet's balance and keeps it spinning consistently. Changes in angular momentum can affect the Earth's rotation speed and axis tilt, which can impact climate and seasons.
What is the significance of the angular momentum of Earth around the Sun in relation to its orbit and rotational motion?
The angular momentum of Earth around the Sun is important because it helps to maintain the stability of Earth's orbit and rotational motion. Angular momentum is a measure of how fast an object is spinning and how spread out its mass is. In the case of Earth, its angular momentum keeps it in a stable orbit around the Sun and helps to regulate its rotation, ensuring that it maintains a consistent speed and direction as it moves through space.
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.
