Answer:
A Quarter Moon occurs a week after the new moon phase, when the Moon has completed around one-fourth of its orbit around the Earth.
The ocean floor's depth varies greatly depending on location. One might assume that the ocean's central areas would be its deepest, but this is often not the case.
The central regions of the oceans feature mid-ocean ridges, which are volcanic underwater mountain ranges. Continuous magma movement leads to rapid cooling, forming new crust. Consequently, the mid-ocean ridges can rise as much as 1.5 km above their surroundings.
As we move away from the mid-ocean ridges—closer to the ocean's edges—the depth actually increases. This occurs due to water erosion and subduction zones. Erosion helps flatten the ocean floor, resulting in greater depths, while subduction zones are where the oceanic plate descends toward the mantle, creating ocean trenches that represent the ocean's deepest areas.
