Wegener's idea of continental drift suggested thatcontinents moved, but it did not explain many otherparts of Earth's crust. Today scientists use the theoryof plate tectonics to explain why Earth's features appearas they do.According to the theory of plate tectonics, Earth's lithosphere is broken into about 20 moving plates. The continents and the ocean floor make up the surfaces of these moving plates.

While there is evidence of tectonic activity in the past, such as volcanic features and fault lines, the overall plate tectonics on Mars are not as active as those on Earth. Some scientists suggest that Mars may have had more active tectonics in its earlier history, but this is still a topic of ongoing research and debate in the scientific community.
Because of the weather, plate tectonics (the movement of the land), as well as the oceans, the surface of the Earth is in a state of constant change.
Yes, that is true. The movement of the pieces of the Earth's crust is explained in a subject called plate tectonics.

When the theory of plate tectonics was first published in the early 1900s, it was dismissed by main stream scientists as being ridiculous - because many if not most of those scientists believed in the "steady state" of the Earth theory - things don't change or change very little. Today, the theory of plate tectonics has been supported by scientific study and discovery, beginning in the 1950s - and the vast majority of scientists today believe in it.
Plate tectonics is the scientific theory that Earth's surface is broken up into huge, slow-moving slabs called tectonic plates. The movement of these plates drives many geologic processes including most earthquakes and volcanoes. Plate boundaries are the areas where two tectonic plates meet.
There are many.
