Earth bulge at equator
Did you know?
WebAug 7, 2024 · The rotation of the Earth about its axis makes it bulge at the equator and contract at the poles due to the centrifugal forces. How do we know, without any external references, that the Earth is spinning if there is nothing to compare it to? For example, imagine it was spinning in empty space with no other objects. WebNow think of the earth as that pizza. The bits of the earth near the equator (a larger distance from the axis of rotation) feel a greater force, and are therefore trying to move outward. The force of gravity tries to pull it back. …
WebThe Earth has an equatorial bulge of 42.72 km (26.5 miles) due to its rotation. That is, its diameter measured across the equatorial plane (12756.28 km, 7,927 miles) is 42.72 km more than that measured … WebOn the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean’s waters toward it, creating one bulge. On the far side of the Earth, inertia dominates, creating a second bulge. In this way the combination of gravity and inertia create two bulges of water.
WebThe moon pulls on the Earth and slows down the Earth’s rotation. The moon’s pull creates a bulge near the Earth’s equator, which means there is a lower level of water at the poles. Related: Earth Facts; Related: How long have humans been on Earth? The Moon’s gravity causes the oceans on our planet to rise and fall. WebAs the Moon’s gravity tugs at Earth, it shifts Earth’s mass, distorting its shape ever so slightly into that of a football ― elongated at the equator and shortened at the poles. This effect on the solid Earth can be detected by scientific instruments, but we can watch the same changes to Earth’s oceans just by visiting the beach. ⚠️
WebThe tilt of the earth exposes different areas to direct sunlight as the earth orbits the Sun. Kepler's 1st law: law of ellipses. The orbit of planets is not circular but elliptical. Kepler's 2nd law: law of equal areas. An imaginary line joining a planet to the Sun sweeps out equal areas in equal amounts of time.
