The answer to your question is A or true.
Answer: Wind speed is also important. The rate of erosion caused by a 30-mile-per-hour wind is more than three times that of a 20-mile-per-hour wind. Wind erosion decreases as soil moisture increases. For example, dry soil erodes about one-and-one-third times more than soil with barely enough moisture to keep plants alive.
