What causes ocean water to be colder at the poles than at the equator ?

That answer is know to be C. Because the sun affects it most but the equator has an affect because of the location. For ex. if its close to Antarctica its colder! like the arctic ocean is absolutely frigid! Hope that this is helpful!

a warm, wet climate will produce the highest rate of weathering. the warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering (figure below). this happens because plants and bacteria grow and multiply faster in warmer temperatures.

i do not know and i have a 100 in this class
