Answer & Explanation:
People depend on the environment for fishing. Many Greenlanders fish in the icy cold water. ... They adapt to the environment by wearing clothes that suit the temperatures and the seasons. Because Greenland has an arctic climate, people need to wear lots of layers in the winter as well as big coats or boots.
During the Ice Age, when the water level dropped and the ocean froze around the Arctic, the Bering Land Bridge (Beringia) formed between Alaska and Russia.
Unlike Earth, Venus lacks plate tectonics to form volcanoes known as "compound volcanoes." Instead, Venus' geography is characterized by "shield volcanoes" generated by hot spots is the difference between volcanism on venus and that around the ring of fire on earth.
Mars and Venus have only shield volcanoes. On these planets, geological processes are vertical and plate tectonics, and significant horizontal tectonic movements do not occur.
The presence of CO2 in Venus' surface atmosphere indicates that volcanism is currently active and clouds of SO2 and sulfuric acid are present.
First, because of the high pressure, Venusian lava requires a much higher gas content than terrestrial lava to explode. Second, the main gas that causes lava explosions on Earth is water, much less so on Venus. Finally, many viscous lavas and explosive eruptions occur near Earth's plate subduction zones.

Answer:
Positive feedback
Explanation:
Positive feedback climate is usually defined as the process where there occur changes in the region where the lighter colored surfaces such as the region of glaciers, ice caps are replaced by the dark-colored surfaces, and this results in the decreasing of the albedo (light-reflecting property) and also increase in earth's surface temperature. This type of feedback is also known as the ice-albedo feedback.
High rate of heating results in the decreasing amount of glaciers and ice-caps, thereby leading to the global warming effect.
Thus, the above-given condition is an example of positive feedback.
