Which of the following are ways to reduce wind erosion?
create windbreaks
cut down trees
irrigate dry fields
plant trees
remove dead leaves

Answers: Create windbreaks, irrigate dry fields and plant trees.

Adding these features to a field or open area reduce the amount of wind which can reach and erode/damage soil. Think of it as adding a layer between the wind and the soil, this reduces contact and therefore erosion.

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.
