its crazy but yes they do
kjn
It may have oceans of liquid water under its layers of water ice. Scientists want to know if these oceans (assuming they are there) contain any forms of life.
they know that there are types of deadly sharks
Megalodons are a rare shark and scientists don't know yet, there are people saying yes there are and scientists saying no there are not, i have a guess that yes there are, but only in the deepest part of the oceans where nobody wants to go.....
fossils
most of the beautiful coral reefs have disappeared
I don't exactly know if they can camouflage, but i do think that they can hide in places where they are not as easily seen. They also live on the bottom of the seas and oceans.
Comets containing ice hit the earth, the ice melted and contributed to our oceans. Scientists don't know what percentage of our ocean came from comets.
Yes China has oceans but i reallly don't know if it has lakes.
To know about scientists life
You might learn something from them you don't know that other Scientist Know better. Also it tells you something you never expected to know.
I assume your referring to the fact that life as we know it requires water. Unlike most substances, frozen water (ice) is less dense than water and floats. If ice was more dense than water and sank to the bottom of the oceans it would not receive enough energy to melt again, and the oceans would freeze from the bottom up. Eventually most of the worlds water would be tied up as ice in the oceans.
