negative feedback: beaches and waves

Question 1

what type of waves causes deposition of beaches? and what does it do to the beach profile?

Answer 1

constructive waves

beach profile becomes steeper

Question 2

what type of waves do steeper beaches favour?

Answer 2

destructive waves

Question 3

what does destructive waves do to the beach profile? and what does this lead to?

Answer 3

destructive waves erode the beach

reducing beach profile

leading to the formation of constructive waves

Question 4

what type of waves occur more in the summer? and what type in the winter? what does this lead to? why might this not occur?

Answer 4

constructive in the summer = more gentle profile

destructive in the winter = steeper profile

lead to dynamic equilibrium

may be external factors to consider other than wave type like wind strength and direction
