Each tectonic plate can move at a slightly different speed but the range of speeds is between 2 - 7 cm/year.
It is interesting to note that Moon is receding away from the Earth at roughly the same rate 3.8 cm/year and that this is about the same rate that adult fingernails grow.
It is also interesting to note that since the physical "Greenwich Meridian" was marked on the ground at the Greenwich observatory, continental drift has moved it (relative to its absolute theoretical position) about 100 meters eastwards. The mark no longer matches where the meridian passes - not even our fixed points are fixed!
When crustal plates move toward each other, they can form convergent boundaries where one plate is forced beneath the other in a process called subduction. This can result in the formation of mountain ranges, deep ocean trenches, and volcanic activity in the area.
The crustal plates float on the asthenosphere, which is a semi-solid layer of the upper mantle beneath the Earth's crust. This layer allows the crustal plates to move over time due to convection currents in the mantle.
Crustal features like mountains, rift valleys, and ocean trenches are directly related to plate tectonics. These features are created by the movement of tectonic plates, which can collide, separate, or slide past each other. The interactions between these plates result in the deformation and creation of various crustal features.
Evidence such as the fitting of the continental coastlines, the distribution of similar fossils across different continents, and the alignment of mountain ranges across separate continents all suggest that crustal plates have moved over time. Additionally, the presence of mid-ocean ridges and magnetic striping on the seafloor provide further support for plate tectonics and the movement of crustal plates.
Lower mantle is the surface on which the lithospheric plates move around earths surface.
The crustal plates (made mostly of low density granitic rock) float on the mantle (made mostly of high density basaltic rock). Convection cells in the mantle move the floating crustal plates around.
Molten magma from the mantle rises at the top oceanic ridge, cools and solidifies, continually forming a crustal plate. Hundreds to thousands of miles from the ridge the plate moves downward into the mantle at the contact with another plate and melts. The continuous process resembling a large "conveyor belt" moves the crustal plate a few centimeters each year.
a fault
The movement of crustal plates is driven by convection currents in the mantle. As these currents circulate, they drag the overlying crustal plates with them, causing them to move. This movement can lead to various geological phenomena, such as earthquakes, volcanic eruptions, and the formation of mountain ranges.
They are geologic features because when the crustal plates move its makes cracks on earth the the mountains are one because everytime the crustal plates move it breaks the earths surface and the dirt and rocks start gathering together
beacause it is moving
an earthquake
by bubbling hot magma in the earth's inner core, erupting from volcanoes and causing earthquakes which cause the crustal plates to move.
2.5 centimeters per year
No, plates and crustal plates are the same thing. They refer to the large, rigid sections of the Earth's lithosphere that move around on the semi-fluid asthenosphere beneath them. These plates are made up of both oceanic and continental crust and are responsible for the movement of continents and the formation of geological features like mountains and earthquakes.
Well, when earths plates move away from each other that's when it happens but move well then NO!
forms when two {crustal} lithosphere plates move apart.
