Explanation:
Seismic refraction is the bending of the seismic waves as they pass geological layers of the earth due to different densities. This is especially true for Primary waves because they can pass through all the layers of the earth both liquid and solid.
Seismic reflectivity is the bouncing back of seismic waves at a boundary of geological layers due to different densities or subsurface formation. This is especially true for secondary waves that are unable to pass through liquid layers of the earth like the outer core and mantle. When they reach the boundary of these layers they bounce back towards the earth's surface.
These properties of P and S waves are used to ‘auscultate’ the epicenter of an earthquake by triangulation.

All living organisms need energy grow and reproduce maintain their structures, and respond to their enviorments: metabolism is the set of the processes that make energy available for cellular processes.
<span>The relationship between two quantities that increase or decrease together is called directly proportional.
It is a directly proportional relationship because being directly proportional means that if one increases so does the other, and if one goes down so does the other.</span>
