The correct answer is B. A hypothesis can be proven incorrect through experimentation

Explanation:

In science, a hypothesis refers to a prediction or educated guess about a certain phenomenon. This is part of the scientific method that aims at explaining phenomena in the world. Moreover, hypotheses are only validated through experimentation; indeed, scientists carry out different experiments following certain standards and then they can conclude a hypothesis is correct or incorrect.

On the other hand, a hypothesis differs from a theory or law because these are proven explanations or rules about a natural phenomenon that can be disproven through new evidence or experiments. According to this "a hypothesis can be proven incorrect through experimentation" is the true statement.

How does the action og wind affect a rock appearance<br>​
Leona [35]
Wind causes the lifting and transport of lighter particles from a dry soil, leaving behind a surface of coarse grained sand and rocks. The removed particles will be transported to another region where they may form sand dunes on a beach or in a desert. Wind erosion is referred to as eolian erosion. Differences in atmospheric pressure will cause the motion of air that can erode surface material when velocities are high enough to move particles.
