Every discontinuity inside the earth can reflect seismic waves. These occur between major layers (crust, mantle, outer core, inner core) and are named after scientists (Mohorovicic and Gutenberg for example).

No, earthquakes are caused by the movement of the different plates of the earth. When one of the plates slips under the other, over the other, or into each other it creates an earthquake.
When slippage and movement of a fault occurs, an earthquake results. A fault is a fracture in the Earth's crust. An earthquake is the vibration of Earth produced by the rapid release of energy, usually along a fault.
The spot on the surface directly above where the earthquake occurs is called the epicenter. It is usually the point on the Earth's surface closest to where the seismic waves originate deep within the Earth.
Earthquakes originate from the sudden release of energy stored in the Earth's crust due to the movement along geological faults. When accumulated stress at a fault line overcomes the strength of the rocks holding it together, it results in the release of seismic waves that propagate through the Earth, causing an earthquake.
The areas under the Earth where earthquake waves bounce off are known as seismic wave reflection zones. These zones occur at boundaries between different geological layers, such as the crust and mantle or between different rock types. When seismic waves encounter these boundaries, some waves reflect back, while others may refract or transmit through the layers. This behavior helps seismologists understand the Earth's internal structure and the properties of various geological formations.
This is known as the focus or hypocentre of an earthquake.
Focus
An earthquake moves due to the plates under the Earth's crust moving
shakes
Focus
An earthquake on land can cause extensive damage and loss of life as buildings collapse. If the earthquake happens under the sea, a tsunami can form and destroy coastal areas and some way inland.
An earthquake is when the tectonic plates under the earth move in different directions causing the earth to shake. Everybody*"GROW WHERE YOU ARE PLANTED"
The plates under the Earth's surface collide together:)
The point beneath the earth's surface where an earthquake originates is called the hypocenter.
A shift in the earth's crust to relieve pressure, and therefore release energy, is an earthquake.
The plates in the earth collide and one goes under the other
