Match the term with its description. terms: acid alkaline ph ion description: a compound that increases the hydroxide ions (oh−) when it is dissolved in a solution. a compound that increases hydrogen ions (h+) when it is dissolved in a solution. an atom or molecule that has a positive or negative charge . a value from 0 to 14 that is used to specify how acidic or basic a compound is when it is dissolved in water.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

it's filtration, but this is an assumption so my apologies if i got this
