Answer: A person can weigh differently at various place on Earth because of the fluctuations in Earth's gravity, according to a new high-resolution map. ... Earth's gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation
Explanation:
Comet is seen after a long period of time. Why?
Answer:
Long-period comets have orbital periods longer than 200 years. ... Since it is the sublimation of these volatiles from the nucleus of the comet as it nears the Sun that gives rise to the coma and highly-visible tails, long-period comets have more material with which to put on a show.

Kyle is playing volleyball. After he hits the ball, it reaches its maximum height and then falls toward the ground due to the force of gravity.
Which statement best describes the interaction between the ball and Earth?
The ball and Earth attract each other with equal magnitudes of gravitational force.
O
The ball and Earth produce equal magnitudes of gravitational acceleration on each other.
The gravitational force exerted by the ball is much less than the gravitational force exerted by Earth.
Earth exerts a gravitational force on the ball, but the ball is too small to exert a gravitational force on Earth.

What kind of waves can cause the most damage on the earth's surface?
Answer:
Surface waves, in contrast to body waves can only move along the surface. They arrive after the main P and S waves and are confined to the outer layers of the Earth. They cause the most surface destruction. Earthquake surface waves are divided into two different categories: Love and Rayleigh.
