Answer;
-The less dense, the more the ice will float, allowing animals to stay afloat and not in the water
Explanation;
-When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.
-This means that ice floats on water and that lakes freeze from the top down to the bottom.This is vital for animals that live on ice, as their habitats would be greatly reduced or not exist at all if ice sank.
Answer:
The correct answer is - Net force.
Explanation:
Adding all the forces that are applied to a particular object, body, or particle is the net force. This overall force that is applied can be calculated by a vector sum of all other forces exerted on the body.
So if two forces are applied in opposite directions to one another, they combine by subtraction whereas If one force is less than the other force, the net force is in the direction of the greater force.
