Detailed explanation-1: -Beaches. A beach is an area of wave-washed sediment along a coast. A beach is formed when a wave drops its sediment on a coast. The sediment deposited on a beach is usually sand.

Detailed explanation-2: -When seafloor spreading rates increase: there is a rise in sea level.

Detailed explanation-3: -Hadalpelagic Zone-Beyond the abyssopelagic zone lies the forbidding hadalpelagic zone. This layer extends from 6, 000 meters (19, 686 feet) to the bottom of the deepest parts of the ocean.

Detailed explanation-4: -x. Three ways minerals leave seawater are by living animals that form seashells, corals, and microscopic diatoms remove chemicals from seawater when they build their skeleton. Second way is, that they form clumps and fall to the bottom of the sea with sediment removing ions.
