Earthquakes are one very obvious example. But there are places where a piece of ground which was once at the same level is now lower than the other, in remote regions where there is no human activity.
south america and africa .
On the surface and under the oceans of the Earth. They vary in thickness from around 2 miles to 80 miles. Every part of the Earth's surface is a tectonic plate. The entire crust is made of these plates. The movement of these plates against each other are what causes earthquakes, many of the worlds volcanoes, and tsunamis. See the links below for information and maps of the worlds tectonic plates.
Yes tho, my book says something like that I how I see here, yes.
because of the earths gravity and constant attraction between sun and earth.
Earth's plates are constantly in motion because of convection currents in the mantle. How this energy translates to individual plates is still not understood. (see the related question)
They currently ARE moving. 24/7 You see, the crust of the Earth is made of plates. Those plates move ever so slightly. But, over those 4 billion years, that movement is large.
This seems kind of weird but if you look closely you can see them move very very slowly and the sand moving.
Pangaea broke apart due to the movement of tectonic plates. The process, known as continental drift, began around 200 million years ago and eventually resulted in the formation of the continents we have today. The movement of the plates continues to this day, causing gradual changes in the positions of the continents.
No. This is because if you see the sky from any tall building, you'll see the clouds nearer. Therefore, when this happens, the movement of the clouds appears much closer. This creates an impression of the earth rotating.
Basically plate tectonics is movement of lithospheric plates on the semisolid asthenosphere, the plates move because of the convectional current produced in mantel of earth. when these plates colloid with each other energy is released in the form of earthquake.
There is evidence of the movement if the earths crust all over the world. The fact that if you look on a map you will see that South America and Africa look like they fit together like a puzzle. There have also been identical fossils found on different continents which enforces the fact that the land masses were once joined and have infact MOVED apart. If there is an earthquake fissures can form which are cracks in the ground where the ground has MOVED apart.
on fault lines. On some fault lines theres accually a visible space and you can see it splitting. I think theres one in Africa and another in California
