Why is water called a polar molecule?

• it is found at the Earth's poles

• it freezes well

• equal charges on the H and O ends

• slightly unequal charges on the H and O ends

Answer explanation

Water is considered polar because they have slightly unequal charges on the H and O ends.  This causes water molecules to be attracted to each other, which causes cohesion.

How is the polarity of water related to cohesion? Click on all that apply.

• water molecules are attracted to each other

• water molecules push each other away

• opposite charges attract

• opposite charges repel

This type of irrigation uses a large system of sprinklers that must be manually moved from field to field and has very large evaporative losses.

• drip irrigation

• spray irrigation

• furrow irrigation

• flood irrigation

This type of irrigation, often used in orchards growing tree crops, distributes water to plants through small parallel channels between crop rows but often leads to increased soil erosion in the field.
