Hello,
Cinder Cone Volcanoes usually make up of Lava. These volcanoes are made of lava, not ash. Do not get that mistaken.

It would help if you had question or attached an image.
Weathering is the decomposition of rocks, soils and their minerals through direct contact with the Earth's atmosphere. Erosion is displacement of solids (soil, mud, rock and other particles) usually by the agents of currents such as, wind, water, or ice by downward or down-slope movement in response to gravity or by living organisms. Erosion occurs because of factors like wind, water, ice, human activities like deforestation etc. Weathering, on the other hand is caused by contact with the earth's atmosphere. These atmospheric conditions may be heat, pressure etc.
That's how they are different.
A concentration gradient must exist. hope this helps
The component of natural selection which is most likely driving the change in phenotype distribution is, that the presence of spines on stickleback caused increased food acquisition and survival in ocean areas.
<h3>What do you mean by Natural selection?</h3>
Natural selection may be defined as a process through which populations of living organisms adapt and change. It involves the favorable variations to carry forward.
Stickleback play a major role in the diet of fish. This structure of fish allows them to feed on small crustaceans and insects.
Therefore, it is well described above.
