(A). Charles Lyell correctly explained how fossils form and formulated some of the basic principles of relative dating
Explanation:
Charles Lyell was a Scottish geologist who demonstrated the power of known natural causes in explaining Earth's history.
Relative dating is the science of determining the relative order of past events, without actually deciding its absolute age.
Charles Lyell's principle of inclusions and components, explains that, with sedimentary rocks, if inclusions are found in a formation, then the inclusions must be older than the formation that contains them.

Answer: The vegetation protect the soil from being picked up and carried by the wind.
Explanation: when the soil is bare of vegetation the wind can pick up and carry sand, small rocks and soil. The sand being carried by the wind can act as an abrasive cutting into rocks, causing further erosion. This is nature's form of sand blasting.
Vegetation protects the soil, preventing the wind from picking up and carrying abrasives like sand and small pebbles. The wind by itself has little erosive power. Without the bare soil where wind can pick up sand there is little wind erosion.
