Answer from: gladyscasper44

Explanation:

Ice floating on water is not due to water surface tension but rather due to density. Ice is less dense than water hence will float on water even though ice is also made of water molecules. The surface tension of water- that allows the insect to walk on water- is mainly due to the cohesive forces of attraction between the water molecules. This even allows small water droplets to support their own weight even under the force of gravity. This is why small water droplets take the shape of a ball or balloon forming a kind of a 'skin' around it.

Floating of ice on the surface of water is not due to the surface tension of water.

Explanation:

It is an object’s density that determines whether the object will sink or float in a liquid. Objects denser than a liquid will sink in the liquid while objects which are less dense than a liquid floats on the surface of the liquid. In this case ice and water both are made up of water molecules but they differ in form.

Ice has lesser density than water and so it floats on water surface. Phenomena arising due to surface tension are given as the remaining options in this question.

This map shows how climate change might affect precipitation patterns in the great plains of the united states by the end of this century. brown shoes a decrease in percipitation, and blue shows an increase. the maps differ based on the predictive levels of green house emissions. the maps shows that northern area should get a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.southern areas show a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.to use these maps to prepare for natural disasters in the great plains, scientist need to ask? a. how many tons of emissions were used at the basis of the map.b. which types of fossil fuels are used in the great plains c. if you think the above is wrong it's probly c the question is cut off
