So in the first case, if you had enough time, you could observe plate motion on the order of feet. In the second case, you have enough precision that you can essentially watch plate motion in real time.
-- The GPS receiver in your hand shows where you are right now.
-- A minute from now, it'll show where you are a minute from now.
-- If you know where you were a minute earlier, and you know
where you are a minute later, you can put that information together
to describe your motion.
-- Except that a GPS receiver shows a new location once every second.
yo but holeLimestone deposits that began as coral reefs provide evidence of how plate motions have changed Earth's surface. These deposits also provide evidence of past environments.
The Earth isn't actually perfectly spherical. It is slightly flattened at the poles. To find evidence of Earth's round shape, pictures taken from space are good secondary data to provide evidence.
the objects fall to the ground
Venus only has two continents and they occupy about 8 percent of the surface. Earth's continents occupies about 25 percent of the surface. Venus also does not have any evidence of plate tectonics.

evidence that supports the conjecture that the Earth is rotating
can be seen at the surface in the form of volcanic activity... novanet

The density of the Earth as a whole has been calculated by observing the orbits of the moon and artificial satellites, trajectories of near earth asteroids, etc. We can measure the density of materials from which the surface is composed. The two are not the same. That tells us that the density of the interior is different from the density of surface materials. Since the overall density is greater than the density of the surface materials, the interior must be denser still in order to bring the overall density to what has been observed and calculated.
