These waves are of a higher frequency than surface waves. The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.

The Earth's molten core can only be traveled through by compressional waves. P-waves travel fastest, at speeds between 4-8 km/sec (14,000-28,000 km/h) in the Earth's crust. S-waves travel more slowly, usually at 2.5-4 km/sec (9,000-14,000 km/h). Sound waves are usually called P-waves and are heard but not often felt.

Answer:

For natural selection to occur, it is true that there must be genetic variation in the population.

Explanation:

According to evolution, natural selection implies the changes that occur in the genotype of a species, due to the effect of environmental factors, and which guarantee its survival through adaptive evolution.

For natural selection to occur, three fundamental conditions must exist:

A trait that can be inherited from one generation to another.

The trait is subject to variability between subjects of the same species.

Genetic variability can determine the possibility of reproductive success and survival.

Therefore, a necessary factor for natural selection to occur is that genetic variability exists in the population.
