Question

Why does the bottom of a lake not freeze in severe winter even when the surface is all frozen?

1. The water has large specific heat
2. The conductivity of ice is low
3. The water has large latent heat of fusion
4. The temperature of the earth at the bottom of the lake is high.​

Answer 1

Answer:

the temp of the earth at the bottom of the lake is high

Answer 2

Answer:

I wish this helps!!

Explanation:

When a lake freezes, the upper layer freezes due to being in contact with the cold atmosphere. This ice sheet doesn't sink as it is less dense than water. This ice sheet acts like a insulator and keeps the water inside warm enough to be in a liquid form. ... But the water below the surface layer does not freeze.
