Which parts of the Earth is gravity stronger than usual, at higher points on the Earth is the gravity stronger or weaker than the lower points and why?

I thought this was against the standards expected here.
You're right. tiny_tim's answer wasn't quite appropriate. He should have answered "This sure looks like a homework question. What do you think? What have you found on your own to answer this question?"truesearch said:As a contributer to physics forums and a teacher interested in hearing the opinions of others can I say that it is very disappointing to find a query being directed straight to Wikipedia.

phinds said:I think the "standards expected here" are that folks will make some attempt to do their on at least modest research before asking questions that such modest research would answer.
It is QUITE common (and I think absolutely appropriate) in such situations to point someone to something they could have found on their own with little or no effort.

elijah18259 said:Okay, thank you <sarcasm mark>. Oh, sounds like a homework question. Wat rubbish.

Darwin123 said:Effective gravity varies with latitude due to the centrifugal force caused by the Earth's spinning.
It also depends on the density of the mantle and crust beneath a surface. Measurements of the gravity of the Earth is called gravitational tomography”.
The strength of gravity throughout the earth is primarily influenced by the distribution of mass within the planet. Areas with higher concentrations of mass, such as mountains or dense rock formations, will have a stronger gravitational pull compared to areas with lower concentrations of mass, such as oceans or valleys.
While the variations in gravity throughout the earth are relatively small, they can still have an impact on daily life. For example, the slight difference in gravity between the equator and poles can affect the weight of objects and cause discrepancies in measurements. Additionally, gravity variations can also affect the earth's rotation and tides.
Variations in gravity are measured using a device called a gravimeter, which detects the minute changes in the strength of gravity. Scientists also use satellite data and other geophysical techniques to map out the variations in gravity across the earth's surface.
No, variations in gravity are not the same all over the earth. As mentioned before, the distribution of mass within the planet affects the strength of gravity, so different regions will have different variations. Other factors such as elevation, topography, and local geology can also contribute to variations in gravity.
Variations in gravity can change over time. Natural events such as earthquakes, volcanic eruptions, and glacial movements can cause temporary variations in gravity. Additionally, human activities such as mining and oil extraction can also affect the distribution of mass and lead to changes in gravity over time.
