The correct answer is - there is no evidence that the changes of O'Higgins are being affected by global warming. It has retreated 9 miles in the past 100 years because of melting.
O'Higgins, as well as the other glaciers in Patagonia and Tierra del Fuego, are still a mystery to scientists as to why are they retreating. They suspect that maybe the global warming is the main cause, but there is no enough data available because of the remoteness and harshness of the region, so for now, it's all just speculation until there's enough data available to make a scientifically proven statement.

Answer:
On a map that represent an elevation from the mean sea level.
Explanation:
- The contour line is a line that is represented on the land surface and has all points of which are shown on the drawn to the same elevation above the datum plane. And they give a three-dimensional effect on the topographic map and defined in terms of the north and south and east and west direction.
So 10 billion people is the uppermost population limit where food is concerned.
Earthquakes are related to volcanic eruptions because when an earthquake happens, two tectonic plates rub against each other. Beneath these tectonic plates is molten lava, or magma. When the two tectonic plates rub on each other, it causes an earthquake, and the magma exerts extreme pressure on the rock, making it to crack. For every crack, there is an earthquake. The crack allows the magma to shoot up, either making it's own volcano under the sea, or forcing another volcano to erupt.
