Uh, I'm not sure if this qualifies as an actual question for any subject. I'm sure you have nice cats though.
Frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.
<h3>Is frozen water more or less dense than liquid water?</h3>
Ice is less dense than liquid water because when the water becomes solid due to low temperature, the density of ice become decreases. Due to less density, the ice floats on the water surface.
Water is attracted due to its polar nature so adhesive forces pull the water toward other molecules. Water is transported in plants through both cohesive and adhesive forces. These forces pull water and the dissolved minerals from the roots to the upper parts of the plant.
So we can conclude that frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.

Answer:
The answer is D good luck
Because the earth's is roughly spherical the sun's light is distributed over a wider area towards the poles, so it has less heating effect... the air cools and falls over the poles and returns to the equator close to the ground. This assumes that there is no other effect (e.g. wind, low or high pressure regions etc.)
