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

How the angular momentum of earth is constant explain how?
T=I A(alpha) , T = I * DALTA W (OMEGA)/DALTA T , SINCE I*W (OMEGA) = DALTA L(ANGLUAR MOMENTUM ) So, T = DALTA L / DALTA T , Thus , As rate of change of anguar momentum is equal to torque . so we know that earth revolves around sun while torque acting on it is zero . so here we may conclude that T=DALTA L / DALTA T , T= O => np change in DALTA L i.e DALTA L = CONSTANT . so now we may conclude that when earth revolves aroung sun angkuar momentum is constant.
Is the moon pulled across the sky by a person animal or force?
The moon orbits the Earth because of its angular momentum. Technically this is a form of energy, rather than a force.
Why does the world pivot on its axis?
The world spins around because of the way the solar system was formed as a spinning cloud of matter. This then it began to collapse in on itself as it did this the heat at the centre became so great that the sun ignited and pushed out all the matter which then formed the planets, still spinning because of the energy from the explosion as the sun ignited.Supplement 2 As far as the planets are concerned, they would have had some net rotational momentum, the residual of all the components that made the planet.This rotational energy cannot be destroyed - it however might be cancelled out by opposite-spin material.BUT back to the question. The Earth carries the residual net spin from its assembly from space debris.Answer:The rotation comes about from the conservation of angular momentum. The formula for angular momentum is:L=mwr2m is the mass,w is the angular velocity in radians per second, andr is the radius of the circular motion.Due to conservation of angular momentum, as the radius of the orbit decreases, then its angular velocity must increase (as the mass is constant). As a consequence the parts of the planet closer to the primary (the Sun) must rotate faster than the parts furthest from the Sun. This causes the spin.This all relates to the fact that planetary and stellar systems are born from the collapse of dense interstellar clouds. As the clouds collapse even a small rotation is magnified by the contraction. If the clouds were not rotating (matter fell straight to the center of the system) there would be no planets.
What direction does the angular velocity vector of the Earth's rotation point toward?
The Earth's angular velocity vector due to its axial rotation points towards the north pole.
Why does the space shuttle fly in the thermosphere?
it doesn't necessarily fly, its in a constant angular free fall around the planet which is what being in orbit means. But if you're asking why the space shuttle stays in the thermosphere, the answer would be because thats the layer of the earth's atmosphere where a space shuttle's velocity is enough to counteract the earth's gravitational pull, creating an angular free fall as mentioned earlier.
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 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 Law of Change that states earth movements at a constant rate?
Do you mean what Law of Conservation keeps the Earth spinning at the same rate? If so, that's the Conservation of Angular Momentum.
If everyone in the world stood on California would the state sink or would the world spin out of orbit?
The state would sink, but not all that much. And angular momentum is a conservative force so the Earth would stay right where it is and the length of the day would remain constant.
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 has the author James P Natland written?
James P. Natland has written: 'Evidences of angular momentum transport in the earth's crust' -- subject(s): Angular momentum (Nuclear physics), Continental drift, Crust
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.
What is the resource that powers wind?
Almost all is from the sun, with a very small contribution from Earth's angular momentum.
