I would say C. Land. The Earth's surface is 71% water. So the remaining would have to be land.
Answer: The release of methane from thawed permafrost
Explanation:
With increasing global warming, permafrost in the arctic is melting. The carbon and methyl clathrates present in permafrost escape into the atmosphere to form carbon dioxide and methane, both greenhouse gases.
In the Arctic, molecules of methane are trapped in ice crystals as methyl clathrates. When the temperature increases, these crystals release methyl clathrates which become methane when in contact with the atmosphere.
The cause of the increasing atmospheric 
is due to the the thawing of dead organisms present in the permafrost. As the permafrost melts, these organisms decay and release into the atmosphere.
Gravity plays an important role in the separation of liquids because it determines the volume of liquids, and therefore, it affects the density.
When you mix different liquids they often separate forming defined layers. This process is possible due to the differences in density (mass/ volume). In this way, the liquid with a lower density will float over the liquid with a higher density.
This phenomenon is affected by gravity or the force that makes everything on the Earth to be pulled towards the center of it. This is because gravity exerts pressure over bodies and affects the volume, which is one of the factors that determines density.

Answer:
Option A will be the appropriate choice.
Explanation:
- The pre-Colombian age encompasses all phase subdivisions throughout American history before the arrival of major European developments on either the American continent, overlapping the duration of the first establishment throughout the Upper Paleolithic era to European colonization mostly during the early medieval century.
- This applies to something like the opportunities ahead of European explorers including colonization arriving.
The other three methods aren't relevant to the particular circumstance. Such that the aforementioned will be the right decision.
