The answer is A: '<span>underwater landslides </span>'. Underwater landslides would cause a wave, rather than a current. Ocean waves are caused by energy passing through water. An ocean current on the other hand is a mass of water moving in a definite direction through another mass of water. This movement is driven by forces that could be derived from surface winds, tidal fluctuations and seawater density contrasts.
It is based on shared characteristics
The correct option is B. The newest crust on earth is located at the actual site of the floor spreading and as new crusts are formed they replace it. Thus, the older the crust the farther it is from the mid ocean ridge.
Sea floor spreading is a geological process in which tectonic plates splits apart from one another. It occurs at divergent plate boundaries.

If the population of the species is significantly decreasing then the species could become extinct. The decline in population is due to some factors like less immigration, aging, and decreasing fertility rates. But the most is due to less immigration which causes to decrease population. The extinction of population can be prevented by some serious actions which should be taken government.
C) As the trait will then pass to others without it and through natural selection will become abundant
