Because the planets are aligning. Some are getting damaged, and that is a whole concept from the past.
Igneous rocks form from molten rock, and rarely have fossils in them. Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions. Generally it is only sedimentary rocks that contain fossils.
A seismograph is used and p waves and s waves are used to determine the distance of the waves
At the point when a oceanic plate crashes into a continental
plate the crust shaping the oceanic plate bents and get pulled under the
continental crust. This is on account of the rocks that frame the oceanic crusts
are denser and more slender than the rocks that shape the continental crust. The
procedure by which the oceanic crust is pulled under the continental crust is
called subduction and the zone at which this happens at the plate boundaries is
known as the subduction zone. At the subduction zone where the oceanic crust
sinks underneath the continental crust, a profound oceanic trench or valley is
made.
