tectonic plates?
Because the Earth's tectonic plates are constantly moving
Im pretty sure it is the Asthenosphere it is the warming, plastic (moving) like upper mantle.
plates keep earth in motion
the earth's surface is made up of tectonic plates, due to convection currents these plates are moving all the time because of this you have huge tectonic plates pushing against each other. the cause of earth quakes is tectonic plates rubbing against each other, eventually these plates push up wards founing huge mountain vistas such as the himilayas. these plates keep moving and this is whay mount Everest grows 4 inches or so every year (might be 4 millimeters)
No, plates will always keep moving because of the convection currents in the mantle under the Earth's crust, as long as the Earth's interior stays hot. This is not likely to happen before the Sun swallows up our planet far, far in the future.
The continents move due to the process of plate tectonics. The Earth's lithosphere is divided into several large plates that float on the semi-fluid asthenosphere below. These plates move slowly over time, causing the continents to also move. This movement is driven by processes such as seafloor spreading, subduction, and mantle convection.
Because the plates keep moving which causes volcanic activity .
It does because the tectonic plates keep moving more upward in that area
because that's where they are colliding. the plates are moving towards each other and they collide and then they keep pushing on each other and may even crumble and that is when the earth cracks and breaks and an earth quake happens. hope this helps! :) :) i love Dallin Dorius! i no that was random, but i do!
Being in the liquid form water keeps on moving on the surface and into the earth due to gravitation force of the Earth.
None. The Earth remains the same size because it does not lose or add material (except for meteorites, which are negligable. Tectonic forces move the -parts- of the Earth around, moving the water out of the way as needed, but nothing is added to or taken from the Earth's size.
Mainly because Earth has a large enough mass, and therefore a large enough gravity, to keep an atmosphere.
