What kind of currents bring warm air to land?
Zinaida [17]

Answer: A warm current is just the reverse. A warm current is moving away from the Equator toward the poles. The water in a warm current is warmer than the surrounding water.

Explanation: The surface water temperature varies considerably between the Equator and the poles. As the ocean water is distributed across the Earth's surface by drifts and currents (see the infrared satellite photo of the warm Gulf Stream moving north along the east coast of Florida), warm water from the lower latitudes is moved into the higher latitudes and cold water is moved Equatorward. If you will remember, we noted in the section on Latitude that this redistribution of heat by ocean water is one of the major ways excess energy is moved poleward (and cold water is moved Equatorward).

I hope this helps, good luck

Damm [24]

Answer:

Option 2.

Explanation:

The fossil proof for the human-chimpanzee last common ancestor (LCA) is rare and scarce due to: These apes lived in an environment of tight or narrow range that was not preserved well in the fossil record.  

Fossil monkeys and prosimians were rare in the Miocene, however, apps were normal and dominant. Option 1 is inaccurate.  

The majority of the apps known from the mid-Miocene are Old World monkeys, who are from an unexpected Linnaean family in comparison to we are is an incorrect statement so it is inaccurate.

The LCA lived in the Paleocene, a time from which we have got a number of the fossil record. so Option 3 is incorrect

Thus, the correct answer is -  These apes lived in an environment of tight or narrow range that was not preserved well in the fossil record.
