Gravity decreases with altitude as one rises above the Earth's surface because greater altitude means greater distance from the Earth's centre. All other things being equal, an increase in altitude from sea level to 9,000 metres (30,000 ft) causes a weight decrease of about 0.29%.
The fastest point on Earth or, in other words, the point farthest from Earth's rotational axis is the summit of Cayambe [14] in Ecuador, which rotates around Earth's axis at a speed of 1,675.89 km/h (1,041.35 mph) and is 6,383.95 km (3,966.80 mi) from the axis.

Map of countries coloured according to their highest point. The following sortable table lists land surface elevation extremes by country or dependent territory. Topographic elevation is the vertical distance above the reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface.
This is a list of lists of places considered the most extreme by virtue of meeting some superlative geographical or physical criterion – e.g. farthest, highest, lowest, greatest, or least. Earth [ edit ]
At a fixed point on the surface, the magnitude of Earth's gravity results from combined effect of gravitation and the centrifugal force from Earth's rotation. [2] [3] At different points on Earth's surface, the free fall acceleration ranges from 9.764 to 9.834 m/s 2 (32.03 to 32.26 ft/s 2), [4] depending on altitude, latitude, and longitude.
The team of college students broke the world record for the highest altitude reached by a rocket launched by amateurs — soaring a whopping 89 miles above the Earth. USC Rocket Propulsion Lab
Centrifugal force from the Earth's rotation, and distance from the center of the Earth, cause the force of gravity to be slightly reduced near the equator. The summit of Chimborazo has about one percent less gravity than the point with the highest gravitational force.
