How do headlands and bays form on discordant coastlines? There are surf breaks all over the Pacific ocean basin. Alternating layers of hard and soft rock allow the sea to erode the soft rock faster, forming a bay but leaving hard rock sticking out, known as a headland.

An in crease in seawater density can be caused by a ___ in temperature or a/an ___ in salinity. a.at a density boundary within the ocean. are formed when electrons are shared by atoms. Multiple Choice Waves converge on headlands due to: A)constructive interference. -When waves with identical wavelengths interfere. A shallow-water wave must form in water depth less than 100 meters. Wave steepness is defined as wave height divided by wavelength. B. capillary wave An eddy about 600 km off the coast of Australia in the southeastern Indian Ocean, which was made visible by a plankton bloom on December 30, 2013 that showed sea surface currents. Waves come into shore and break parallel to the coast because ocean floor topography is generally similar to the shape of the beach. The map below shows some popular surf spots.

Make Print-Friendly, When you're ready to print, just click this button: Fig. 5.18. If the bottom is very steep, a plunging wave becomes a collapsing wave, when the top of the wave breaks onto the lower part of the wave.

Waves at the ocean surface are ____ waves. Of the following statements about ocean waves, which one(s) describe wave period? A wave may break more than once, and in different ways, as it advances to shore. the distance over which wind blows without interruption. In addition, for many the ocean is a source of inspiration, recreation, rejuvenation, and discovery. Combinations of each type of wave often occur in a surf zone. You can use the same procedure to make a profile of the area outside your classroom.
