It is because of many things like gravity and inertia. Gravity is what holds you down on earth and not float away like you would on the moon. Inertia is used a lot in the game pool. When one ball hits another, the one that got hit takes away the first balls speed. I hope that answers your question and i was glad to help you.

First, the Earth's axial tilt cannot be changed without tearing the Earth apart. The spinning Earth is like an enormous gyroscope; it won't tilt unless you were to exert titanic forces to rotate it. The gyroscopic precession would then rip it apart.

If the Earth had less axial tilt than it does, the effect of "seasons" would be lessened. There would be less difference between summer and winter, and the weather would be a little more predictable.

The weather and friction between the atmosphere with particles in space is slowing the rotational speed of the Earth (between 0.3 and 1 millisecond and per year). Not noticeable in human situations it is measurable and over he next billion years will amount to noticeable amounts.

The days and nights get longer.

The Earth's rotation is, in fact, slowing. But not at a rate that anyone would notice-unless one happens to be around in 150 million years. Using eclipse data from as far back as 2000 BC, scientists estimate that the period of Earth's rotation is growing by approximately 1.7 milliseconds per solar day per century. In other words, the Earth Day has gotten roughly 0.07 second longer in the last 4,000 years.

Personally, I do not think it can because in one subject at secondary school we were learning about the big bangs with all the atoms and the fire balls etc... and on a tape we saw an interview with a researcher and scientist told us that the Earth is infact speeding up. Hope that helped. :)

Decreasing just a bit, but it is going to be several billion years before it becomes a problem. I wouldn't worry about it.

The tilt of the earth has remained pretty constant for millions of years. The gravitational force of the moon helps limit how much the tilt can change.

the earth slows down because of the friction between the earth and the moon.

The tides are a form of energy, and some of this energy is lost, eventually. This energy com from the Earth's rotation, so logically, if tidal energy is lost, the Earth's rotation slows down.

The main cause is tidal friction

What is shape and size of the planets?

Planets, by definition are all approximately spherical in shape, though their axial rotation often means that they are oblate spheroids (look like `squashed spheres`, longer across the equator than from pole to pole). The size of the planets varies; Mercury's diameter (at the equator) = 4880km or 0.3825 x Earths diameter Venus' diameter = 12104km or 0.9488 x Earths Earth's diameter = 12756km Mars' diameter = 6794km or 0.5323 x Earths Jupiter's diameter = 142,984km or 11.21 x Earths Saturn's diameter = 120,534km or 9.45 x Earths Uranus' diameter = 51,114km or 4.01 x Earths Neptune's diameter = 49,532km or 3.88 x Earths


What affects seasonal change more Earth's tilted axis or the distance to the sun during Earths orbit?

seasons are caused by the tilt of the earth. since the earth is in a slight eliptical orbit around the sun, when we are closer to the sun in January is where the northern hemisphere will still have winter and further from the sun in July when summer occurs. this is expected to flip in 26,000 years because of earths 3rd axis known as axial precession


Which planet has the most axial tilt?

Uranus, at 98° axial tilt. Sometimes the answer is given as "Venus" with a tilt of about 177 degrees. It depends how you define "north pole"


How does the moon influence the earths axial tilt?

The moon stabilizes the Earth's axial tilt, like a counter balance. Picture someone swinging a bowling ball around their body, at the end of a 3 foot (1 meter) chain. If they get the ball spinning fast enough, they will have to lean back to counter the centrifugal force of the bowling ball. When the rotational velocity is stable, and the person's angle of leaning is stable, it is a suitable representation of the Earth-Moon system. The bowling ball is the moon, the person is the Earth.


Why does Mars have similar seasons to Earth's?

That's because Mars has an axial tilt which is almost the same as the Earth's. A planet's axial tilt is the most important factor in determining the seasons.
