The important parameters of a wave are its amplitude, wavelength, and speed. Waves don't always flow towards the shore, it just appears that way. Most of the incidents on the Great Lakes are caused by structural and rip currents, so it is reasonable that we see a large number of the incidents occurring when waves are approaching the beach at oblique angles (GLCID, 2020).

This difference in wave energy also explains why there is net erosion on points, while sand and sediments get deposited in bays (see section 13.3).

The distance over which the wind blows over open water. d. warm and salty, An isotope has the same number of ___________ but different number of __________. However, most waves still reach the shore at a small angle, and as each one arrives, it pushes water along the shore, creating what is known as a longshore current within the surf zone (the areas where waves are breaking) (Figure 13.2.1). B. Loess Oblique shocks are generated by the nose and by the leading edge of the wing and tail of a supersonic aircraft. Remember that in deep water, a waves speed depends on its wavelength, but in shallow water wave speed depends on the depth (section 10.1). { "12.01:_Coasts" : "property get [Map
