so when the moon is 90 to the Earth, there are higher high tides.dTides forced into a restricted shoreline create higher high tides.Question 7(1 point)Which statement best describes seamounts?aThey are a special type of oceanic trench.bThey are submarine canyons found near Australia.cThey are volcanoes that form on the ocean floor.dThey form only in the Pacific Ocean basin.Question 8(1 point)Which statement is NOT true of deep-ocean trenches?aThey are geologically very stable.bThey are long and narrow depressions.cThey are sites where plates plunge back into the mantle.dThey may act as sediment traps.Question 9(1 point)Which of the following is NOT associated with turbidity currents?adensity currentsbdeposits of graded bedscexcavation of submarine canyonsdformation of seamountsQuestion 10(1 point)A sand ridge connecting an island to the mainland or to another island is called what?abreakwaterbjettycsea stackdtombolo
