Mason notices that his boat sinks lower into the water in a freshwater lake than in the ocean. what could explain this?

the boat is less dense in salt water.

salt water is less dense than freshwater.

salt water is more dense than freshwater.

option (d)

Explanation:

The buoyant force acting on the body is directly proportional to the density of fluid in which the body is immersed.

As the density of sea water is more than the fresh water, so it experiences lesser amount of buoyant force, so, sinks lower into fresh water than sea water.

So, sea water is more dense than freshwater.
