What is the simple explanation for the cause of an earthquake?
The Earth's hard outer shell is called the lithosphere. If too much pressure is applied to the lithosphere it responds by breaking where splits or fractures form through it. This is known as brittle deformation. As the Earth has formed over time, this hard outer shell of Earth has been broken up into a number of large pieces known as tectonic plates which move around very slowly on the underlying material. Where two or more of these large pieces bump into each other or scrape past each other, these parts of the plates can become locked together. However the rest of the plate is still moving and eventually this causes the parts of the plates that are locked together to be wrenched apart very suddenly. This releases lots of energy and causes the ground to shake. Depending on how long the plates have been locked together and how much movement occurred when they are wrenched apart controls how much energy is released and how violent the shaking that occurs.
Why are tsunamis in the world?
this happens when the earth's tectonics plates have rubbed together for a long time on a fault line over a long time this pressure builds then suddenly releases and this a displacement of water ties to spread out, and this causes tsunamis it they happen to reach land and they are big. This is what I learnt
Will the plates ever stop moving?
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.
What is the long crack that forms as two tectonic plates move apart?
Itis called a rift.
Why does the ocean plate and the continental plate move against each other?
The Earth's rocky outer crust solidified billions of years ago, soon after the Earth formed. This crust is not a solid shell; it is broken up into huge, thick plates that drift atop the soft, underlying mantle.The plates are made of rock and drift all over the globe; they move both horizontally (sideways) and vertically (up and down). Over long periods of time, the plates also change in size as their margins are added to, crushed together, or pushed back into the Earth's mantle. These plates are from 50 to 250 miles (80 to 400 km) thick.Oh and if you want to know how to make things huge: go to power point and copy down what you want then copy and paste.
Where is the rocky mountains located and how do they form?
the rocky mountains are located in North America. A long time ago, there was one big continent on the planet earth and soon enough, it drifted apart into plates. When those plates crashed together, they forced the earth's crust to go up, and over time the plates were pushed together so much, it forced them really high and they formed the Rocky mountains.
What is long crack where plates diverge?
Itis called a rift.
Long deep cracks formed when plates separate?
rift vally on land, and mid-ocean ridge under water
What does Pangaea have to do with plate tectonics?
Pangaea is the name of the super continent that existed about 250 million years ago, before they separated to form the continents we know today. It has to do with plate tectonics because the theory of continental drift (proposed by Alfred Wegener) says that the plates are moving because of sea-floor spreading
What is the cause of the currents that make plates move across the earth?
Radioactive decay of long-lived isotopes in the Earth's deep interior is the source of heat which causes convection currents in the magma which causes tectonic plates to move.

What are long cracks in the earth's crust called?
It's called a "fault"

How earthquake changes the earth?
when an earthquake occurrs tectonic plates can shift slightly. over long periods of time along with the natural movement of the techtonic plates countries move. you could also consider uplift and downfall of the earth's crust during an earthquake. not to mention the fracturing of the earth when it is affected by the earthquakes energy
What is formed when the plates move apart at some boundaries and collide at others?
At collision, mountains, at separation, long deep holes into the earth.
How do earthquake occurs?
Very :P
