What is the causes of earthquake?
An earthquake is caused by a sudden slip on a fault. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel. In California there are two plates – the Pacific Plate and the North American Plate.
Do all faults cause earthquakes?
faults. While all earthquakes occur on faults, not all faults have earthquakes. A fault is simply a fracture in rock material accompanied by displacement along the two sides of the fracture. If the displacement occurs slowly enough, no earthquake waves are generated.

What is the cause of most earthquakes group of answer choices?
Earthquakes are the result of sudden movement along faults within the Earth that releases stored up elastic strain energy in the form of seismic waves that propagate through the Earth and cause the ground surface to shake.
When the Earth’s plates come together we find?
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.
How do Earth’s movements affect humans?
The movement of the earth affects our lives in many ways. One of this is its affect in the seasonal change of our climate. As the earth’s accelerates, all the things on its surface go along with it, including the air and atmosphere. This is because the force of the gravity holds everything on earth down.
What is the biggest tectonic plate?
Pacific Plate
Why our earth is called unstable?
The plates move because of convection currents in the Earth’s mantle. These are driven by the heat produced by the natural decay of radioactive elements in the Earth. Where tectonic plates meet, the Earth’s crust becomes unstable as the plates push against each other, or ride under or over each other.
Why is the Earth always moving?
Earth spins on its axis once in every 24-hour day. At Earth’s equator, the speed of Earth’s spin is about 1,000 miles per hour (1,600 km per hour). It’s because you and everything else – including Earth’s oceans and atmosphere – are spinning along with the Earth at the same constant speed.
What is the meaning of earth plates?
earth plate(Noun) An electrode, in the form of a metal plate buried in external soil, used to earth the electrical system of a building.
