Question

1. how are a surf wave and a swell different?

a a surf wave crashes into the shore.
b surf waves get smaller in length but larger in height.
c swell waves are low and wide.
d all of the above

Explanation:

To determine the difference between surf waves and swells:

• Option A: Surf waves do crash onto the shore, while swells are waves that travel in open water before reaching the shore.
• Option B: As surf waves approach the shore, their wavelength decreases (get smaller in length) and height increases (larger in height) due to the shallowening of water.
• Option C: Swell waves are typically low - amplitude (low) and have a longer wavelength (wide) as they move in open ocean.

Since all of these statements (A, B, and C) correctly describe the differences between surf waves and swells, the correct option is D.

Answer:

D. all of the above
