Answer:
changes in temperature that happen with increasing altitude.
Rain forest plants all work together to provide food and shelter for rain forest animals, as well as to convert carbon dioxide to oxygen. Ground-level competition for light and food has resulted in some unusual plant evolution.
The given blank can be filled with a feature resulting from hot volcanic rock.
The geysers refer to the rare characteristics on Earth, only about 1000 of them prevail, and more than half of those are situated in Yellowstone. For a geyser to develop, there must be a source of volcanic heat, enough groundwater, and a geologic plumbing system via which the heated water can escape.
The absconding of water takes place when the groundwater is heated by the hot volcanic rocks. The intensifying steam bubbles push the water above via the fissures in the rock until they overflow from the geyser.
With the absconding of the top layers of the water, the pressure on the hotter waters below diminishes, leading to a violent chain reaction of explosions, which expand the volume of the rising boiling water by up to 1500 times or more.
