Stabilizing selection, directional selection and disruptive selection are the three types of natural selection.
What are these types of selection?
Natural selection is the process wherein organisms get better adapted to their environments and tend to survive and produce more offsprings. It is basically a mechanism of evolution which favors those organisms that can better adapt to their environment.
Directional selection: this theory states that an extreme phenotype (a characteristic or trait) is favored over other phenotypes and this causes the allele frequency to shift in favor of the extreme phenotype over time. A particular trait, if favorable, will be expressed in the population at the most beneficial frequency.
Stabilizing selection: in this type, meaning a non-extreme trait is favored instead of one of the two extreme traits. Stabilizing selection is said to be the most common mechanism for natural selection, because most traits do not change drastically over time.
Disruptive selection: This selection is bimodal. It favors both of the extreme traits in a population.
So therefore, stabilizing selection, directional selection and disruptive selection are the three types of natural selection.

Explanation:
Step-by-Step
Magma composition determines both eruption type and volcano type.
Composite cones are built of felsic to intermediate lava and shield volcanoes of mafic lava.
Cinder cones are made of small fragments of a variety of compositions usually from a single eruption.
