ThE centre or core
if there was no tilt we would not have any seasons because no part of earth would be tilted toward the sun.:))))))
The densest part of earth is the core.
No, earth's crust is not part of the atomosphere.
Because the value of "g" varies directly with the sum of the masses of the two bodies acted upon by the force of gravity. If you go inside the earth, only part of the mass of the earth will be attracting you toward its center; the mass of the part of the earth that is farther from the center than you are will be attracting you away from the center. If it were possible to reach the center of the earth, the value of "g" would reach zero because the mass of the earth would be acting upon equally you in all directions.
Earth
You're talking about "gravity". But after a brilliant statement in the first partof your question, you dropped the ball for the second part, and missed oneof the beauties of gravity.Yes indeed, gravity causes two objects to pull toward each other. That means thateverything is pulled toward the center of the earth by gravity, while the earth ispulled to the center of everything by the same force.Whatever you weigh on earth, the earth weighs the same on you. Is that cool or what !
Summer
The Earth tilts toward the sun at an angle of 23.44 degrees, because the Earth rotates, the entire Earth tilts toward the sun during summer and away from the sun during winter.
Its tap root
Summer!
Because the moon comes between the sun and Earth, casting the moon's shadow on Earth.
Yes. The seasons occur because the part of the Earth tilted toward the Sun is different at different times of the year, and so at one part of the year it will be warmer than at another.
The exact scientific explanations of gravity are far too complex for this forum. The simple explanation is that every body that has mass attracts every other body that has mass. The more massive the two bodies are the more they attract each other. The more distant they are, the less they attract. Earth has a huge mass, billions and billions of times the size of a human. All of that taken together pulls everything and everyone toward the center of the earth. You may not be aware of it, but your body is also pulling the earth toward you. We can see the effect of a smaller body pulling on a larger one when we see the tides. The moon, a quarter of a million miles away, is affecting the water and the outer crust of the earth, even though the moon is only a little more than 1% of the earth's mass. Further out, tiny Pluto was discovered (in part) because it was affecting the orbits of the gas giant planets Neptune and Uranus.
In a sense, it is falling toward earth, but its orbital velocity causes it to miss from moment to moment. The moon is in a stable orbit around the earth, and that is due in part to the gravitational pull between the earth and moon, and in part to the moon's own velocity as it travels in its orbit. If we could put some unimaginably powerful rockets on the moon that would push sideways (not down toward earth) in such a way that the moon's orbital velocity would slow a great deal, then the moon WOULD fall to earth, and it would cause more trouble than a falling apple.
when Earth rotates on its axis then one side of the Earth turns toward sun and the other part is at dark side.so we experience dark.
This is due to the tilt of the Earth and the equinoxes. During the northern summer months, the Earth's axis is tilted in a northward direction, toward the sun, and vice-versa for the southern hemisphere.
If the north part of the earth's axis it tilted toward the sun, North America should have warm weather caused by longer days.
