The ice has less density than liquid water, so it floats on the water surface. Therefore during the winter all the lakes and rivers are frozen only at a top. Deeper layers of water are cold, but still liquid and it allows fish and other organisms to survive. Moreover, the ice cover provides temperature isolation so liquid water beneath the ice has more or less constant temperature (around 4 dgr Celsius)
The planet would growl and die . Also our magnetic shield would be gone and that would allow for cosmic radiation to hit the earth
Oxygen Depleting can cause Warm water. During summer, The upper layer of the water is lighter therefore it does not mix with the cooler water below. Which soon becomes stagnant. (Oxygen becomes depleted and toxic compounds may produce).
That is one of them. I hope it helps. I'm not so good when it comes to this type of science. But if you ever need help with Anatomy Or anything similar to that. I will gladly help.
