Which statement best describes how the temperature of the oceans surface water varies

areas with high density have the warmest water
areas at high latitudes have the coldest water
areas close to the poles have the warmest water
areas with low salinity have the coldest water

areas at high latitudes have the coldest water

The top layer of the ocean water is called as surface layer. The temperature of the surface water varies mainly with the latitude. The high latitude like Polar Seas remains cool hence, the water is cold, whereas the low latitude like Persian Gulf remains warm, hence, the water remains warm.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
