Salinity (how much salt) of the water and low temperatures
An ocean is much bigger and deeper. A lake is much smaller in size and is not as deep. In addition, the oceans are salt water while most lakes are fresh water.
The seahorse is a species of fish that live exclusively in salt water. They do not live at the bottom of the ocean but prefer to live in the shallow waters near the coastline.
oceans have salt water, no fresh water.
The oceans surface is 100% water.

There is greater pressure the deeper you go in water. So if you go too deep, the pressure in the human lungs will be so great and too much that the persons lungs will collapse.
Oceans are large bodies of saltwater that cover the majority of the Earth's surface, while lakes are bodies of freshwater surrounded by land. Oceans are interconnected and have significant influence on global climate, while lakes are typically smaller and more isolated ecosystems. Oceans have tides and currents, while lakes do not have the same level of dynamic movement.
Deep Currents Occurs when the density of the water increases. Density is based on two main things it is the Salinity is how much salt and other solids are in it and it is also the temperature of the water.The lower the temperature the lower the dense the water becomes. Salinity (how much salt) of the water and low temperatures.
