Whats the difference between a pond and a lake?

At first glance, they seem very similar! To help determine the difference, both the depth and surface area must be considered. Lakes are normally much deeper than ponds and have a larger surface area. All the water in a pond is in the photic zone, meaning ponds are shallow enough to allow sunlight to reach the bottom.

Why is the ocean salty?

Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.

Is it possible to make a lake deeper?

Unlike ponds with manmade liners, it’s possible to make natural ponds deeper and larger without the added work of draining the pond and removing the liner first.
