Earthquaks are caused by the earths tectonic plates moving over each other.Nothing is caused by the earths crust its just dirt and rock.
The asthenosphere.
not necessarily but its not unheard of. mainly they make earthquakes or in some cases they form mountains over time
The earth's crust is unstable because it is divided into large plates. These plates push against each other and move slowly, going over and under each other.

the tectonic plates lol
EARTHQUAKES have changes the earth in many ways. The folding and faulting of the earth crust have left big cracks in the earths crust. The folding and faulting only happen on the tectonic boundaries. TECTONIC BOUNDARIES: The plates that make up the earths contents.
Mountain were made by huge segments of the earth's crust also know as tectonic plate. Over millions of year of volcanic activity under the earths crust forced these plates to shift. When to plates meet, the force of the volcanic pressure and the to plates may be pushed upward and create mountains.
The asthenosphere.
an earthquake forms deep in side the earths crust, where plates, that hold continents, are. they move, sideways, forward, backward and slide over other plates. if two plates meet sliding or bumping each other, it cause waves over the earth, which we call earth quakes.These waves, animals can sense. there are three diffrent waves that come from an earthquake.P waves S waves and surface waves. the waves come over the earth, and some are silent at first,which the animals hear. the big ones, shake the earths crust, causing the crust to shake which we are on and buildings. and since the earth below us is moving, the building shake and fall, causing damage.
When earths plates collide together
Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep. The lithosphere is broken into giant plates that fit around the globe like puzzle pieces.
Sea floor spreading occurs due to the movement of tectonic plates away from each other. This movement creates a gap or rift at the mid-ocean ridge where magma rises up from below the Earth's crust, solidifying to form new crust. Over time, this process results in the continuous widening of the sea floor.
These are individual broken slabs of gigantic masses, that makes up the earths crust and are capable of floatational movement over the weak, plastic, hot and highly molten portion of the mantle called the asthenosphere.
It's called 'plate tectonics' - and explains that the Earth's crust is composed of large pieces (or plates) that 'glide' over the molten mantle beneath.
