Waves

Question 1

Name 3 factors that affect the size and energy of a wave

Answer 1

*how long the wind has been blowing.
* the strength of the wind.
* how far the wave has travelled (called the fetch).

Question 2

Describe destructive waves

Answer 2

Backwash is stronger than swash therefore erodes the coast. Occur when wave energy is high and the wave has travelled over a long fetch. Have a short wave length and are high and steep

Question 3

Describe constructive waves

Answer 3

Swash is stronger than the backwash therefore build up coast. Have a long wavelength, low height and are less steep
