Astudent is making a diagram of the water cycle. what should the student draw to illustrate precipitation? a. an arrow pointing from a cloud to the ground b. an arrow pointing down a hill to a body of water c. an arrow pointing from a plant's leaves to the sky d. an arrow pointing from a body of water to the sky

Option (A) is the correct answer.

Explanation:

Precipitation is defined as the occurrence of a solid substance due to the reaction between solid of liquids in water cycle. This precipitate appears in the form of rain, sleet or snow etc on the surface of earth.

Precipitation process occurs in clouds due to which snow, rain etc falls from clouds to the ground.

Thus, we can conclude that the student should draw an arrow pointing from a cloud to the ground to illustrate precipitation.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
