What causes some plates to move faster than others?
2019年11月25日 · It means that it is the subducting plate which controls the velocity of the plate's movement. And the rate at which a plate sinks depends mostly on its age/temperature/density: older plates are cooler/denser, thus they sink at a higher velocity than younger plates.
geology - How do tightly packed plates move in the theory of …
The plates move by sliding under each other, melting, or bending Take a toffee-bar candy, hang most of it off the side of a table and put something heavy on the other end to hold it in place, wait a few hours, just under its own weight it will bend 90 degrees.
(1) Why do the plates move? class 7 - Brainly.in
2023年6月22日 · As the asthenosphere moves, it exerts a force on the overlying tectonic plates, causing them to shift. There are three main types of plate boundaries where the movement of plates occurs: 1. Divergent boundaries: Here, plates move away from each other. Magma rises to fill the gap, creating new crust and causing the plates to separate. 2.
Why do the plates move class 7 - Brainly.in
2023年12月7日 · The plates move due to the movement of tectonic plates and the forces associated with plate tectonics. Explanation: The movement of plates is primarily driven by the process of plate tectonics. The Earth's lithosphere, which is composed of several large and small tectonic plates, floats on the semi-fluid asthenosphere beneath it.

Why do plates move? - 32290740. Tectonic plates move due to the heat and convection currents in the Earth's mantle.
Why do tectonic plates move? - Brainly
2021年12月20日 · The Earth’s tectonic plates are constantly moving like giant ‘rafts’ on top of the semi-molten mantle below. However, this movement is slow and rates vary from less than 2.5cm /yr to over 15cm/yr. One explanation for the movement of the Earth’s crustal plates is believed to be convection currents which occur in the semi-molten mantle.

2014年10月21日 · $\begingroup$ On wikipedia tectonics page it says under the heading of rotational drivers for tectonics: "Pole flight force: equatorial drift due to rotation and centrifugal effects: tendency of the plates to move from the poles to the equator ("Polflucht");" if that's of any help $\endgroup$ –
Why do plates move class 7 geography - Brainly
These are seven major plates and several small plates. These plates are move slowly (just a few millimetres every year). This is because of the heat generated by the molten magma of the earth inside it. The molten magma inside the earth moves in a circular manner. The movement of these plates causes changes on the earth surface. HOPE IT HELPS YOU
How did Earth's plate tectonics start?
Plate tectonics is a theory which describes Earth's lithosphere as being composed of distinct plates which are able to move atop of the underlying asthenosphere. At plate boundaries, this movement can give rise to convergent boundaries where subduction may occur, divergent boundaries, where molten lava rises to fill the gaps between diverging ...
Why do crustal plates move? - Brainly.ph
Why do crustal plates move? - 4540582. Answer: Tectonic plates are able to move because the Earth's lithosphere has greater mechanical strength than the underlying asthenosphere.
