– Hydrological Cycle:
The hydrological cycle describes the movement of water on, in, and above the earth. It is vital for all life forms on the planet as it ensures the continuous circulation of water in different forms【4:0†source】.
– Oceans – Submarine Relief and Distribution:
The relief of the ocean floor includes continental slopes, deep sea plains, trenches, mid-oceanic ridges, seamounts, submarine canyons, and guyots. These features play a significant role in oceanic geography and plate movements【4:4†source】.
– Distribution of Temperature and Salinity:
The temperature of ocean water varies due to factors like latitude, prevailing winds, unequal land-water distribution, and ocean currents. Salinity varies across different oceans based on factors like melting ice, evaporation, and freshwater influx【4:1†source】【4:2†source】.
What percentage of the planetary water is found in the oceans?
Explain the concept of the hydrological cycle in relation to the circulation of water on Earth.
Describe the major divisions of the ocean floors.
What factors contribute to the formation of relief features on the ocean floor?
How does salinity in water bodies vary globally, and what factors influence these variations?
