Any change in density will cause diffraction (and or reflection) of seismic waves.
Some key density boundaries include the Moho or Mohorovičić discontinuity which marks the boundary between the crust and the mantle, and the Gutenberg discontinuity which marks the boundary between the mantle and the outer core.

the earths gravitiy causes it to push down
why do you think scientists study earths interior?if you were a scientists ,will you undertake a study of the earths interior?
Rising materials causes rifting; sinking material causes subduction.
The energy from the core of the earth causes currents in the molten layers, the way there are currents in the ocean. These currents are what causes the Tectonic Plates to move along the surface of the earth.
Because of the study of seismic waves from earthquakes

mostly earthquakes or plate tectonic movement.
Volcanoes are caused by the rising of magma in the earths mantle and earthquakes are caused by the colliding of the earths tectonic plates against one another.
