On average, the Americas move about one inch further away from Europe and Africa per year. The landmasses move away from each other due to a phenomenon called continental drift, where the tectonic plates that continents sit on are in constant motion and can drift toward and away from one another.


How much do the continents move per year? they move about the same time it takes for your nails to grow per year, which is about 6 cm. share with friends. Share to:


As the seafloor grows wider, the continents on opposite sides of the ridge move away from each other. The North American and Eurasian tectonic plates, for example, are separated by the Mid-Atlantic Ridge. The two continents are moving away from each other at the rate of about 2.5 centimeters (1 inch) per year.


How much do the continents move per year? ... Of course, as certain continents move apart from each other, theyalso are moving closer to other continents. share with friends.


So with this in mind, how far do the continents move each year? Once upon a time, all over the seven continents were joined together in one massive super continent called Pangaea. Because of a process known as plate tectonics, this content eventually began to split apart. Landmasses rest on large masses called tectonic plates.


For 40 million years, the plates that made up Pangaea moved apart from each other at a rate of 1 millimetre a year. Then a shift in gear happened, and for the next 10 million years the plates moved at 20 millimetres a year. According to the new model, the continents split completely some 173 million years ago.


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...

Earth's tectonic plates are constantly moving -- just like you heard -- at about the same rate our fingernails grow. That amounts to, at most, a few inches per year. Geologists think that sometimes the continental crust is all pretty much in the same part of the globe (like Pangaea) or split into a lot of different continents (like now).


It is a relatively slow movement, driven by thermal convection currents and other geological activity originating deep within the earth's mantle. This theory of plate tectonics replaced the previous one of continental drift, where it was thought that just the continents themselves drifted over the earth's surface.
