The continents are still moving today. Some of the most dynamic sites of tectonic activity are seafloor spreading zones and giant rift valleys. In the process of seafloor spreading , molten rock rises from within the Earth and adds new seafloor ( oceanic crust ) to the edges of the old.
There are mountains of evidence (literally) that plate tectonics has taken place in our planet's past. But how do we know that the continents are still drifting, right now? And how do we know what direction each one is moving, how fast they're going . . . how do we know what we know about plate tectonics?
Yes, they are still moving now. Some are moving at about 3 cm/year, some much more (up to 7–10cm/year), and some less. Each of the tectonic plates that the continents “ride on” (they are the lighter and less dense materials on the tectonic plates) as they interact with other plates in various ways change the surface of the Earth.
Continental drift is the theory that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his theory was reje...
Slowly, as the plates moved, the one huge continent broke into two continents. And, as the plates continued to move, both of these continents broke up to form the seven continents we know today. As the plates keep moving, the continents and seas are still changing shape.
Creeping more slowly than a human fingernail grows, Earth's massive continents are nonetheless on the move. Geologists say that in 250 million years the Atlantic Ocean could be just a distant memory while Earthlings will be able to walk from North America to Africa.

Best Answer: Yes, we are still moving. Plates move 5-10cm per year, depending on the plate. And you can feel it moving, every time there's an earthquake. The earth doesn't rotate around the sun, it revolves. It does rotate though, we can't feel it, because the movement is also extremely slow and doesn't ...
A new landmass discovered beneath a tiny island off the coast of Madagascar is a reminder that Earth’s continents are always on the move, continuously drifting together before breaking apart in ...
Just what produces the awesome forces that can split and move the continents is still an ongoing process of discovery today. The study of continental drift, it's history and the forces that cause it, constitutes the branch of geology known as Plate Tectonics.
