New oceanic plates/crust are created in the space of separation.
Most earthquakes happen at the plates because the plates (continental plates) sometimes move. If it moves and slides against another one going the other way, the plates' connecting part will tremble and shake and fall apart. It starts like this: 1. The plates start to move. The land between, roads, and other things bend. 2. The plates suddenly break, and some of the roads get carried away, so everything falls apart.
They can move apart or in some rare cases together.
It forms a hole but new crust is formed.
Magma wells up as the plates move apart and fill some of the gap.
Some move away from each other and create massive trenches normally in the sea bed, for example the Mariana Trench - 10,998 m.
At collision, mountains, at separation, long deep holes into the earth.
No, tectonic plates move at different rates. Some plates move faster than others, while some plates move very slowly. The movement of the plates is driven by the underlying convection currents in the Earth's mantle.
The process called plate tectonics is responsible for plates pulling apart. Over time, and with the combination of carbon dioxide, erosion, and force, plates are able to pull apart. This will eventually cause some plates to separate from one another.
Some plates are moving faster than others in plate tectonics because of differences in the forces acting on them. These forces can be influenced by the boundaries between plates, such as divergent boundaries where plates move apart, or convergent boundaries where plates collide. The speed of plate movement can also be affected by the temperature and composition of the rocks making up the plates.
The new plates come in at different times. Some states comes in annually and some many years apart.
Yes. Tectonic plates are extremely strong and catastrophic in some cases.
because if the sea-floor is moving it will probably will move a chunk of land that could be part of a continent the land at the bottom of the ocean is being spread across, and is taking space up. the continents are on tectonic plates, and need to go some where and move away.
