Answer:
Geologic features that are often associated with volcanoes or volcanic areas include craters, calderas, volcanic vents, geysers, and hot springs. Depressions commonly found at the top of volcanoes are craters.
Usually, the main cause of climate change is the " greenhouse effect" which warm the earth's surface as a result of atmospheric pollution by gases, the particular greenhouse gasses such as carbon dioxide, water vapor, methane, ozone , and chlorofluorocarbon that heat from earth's surface is absorbed by atmospheric greenhouse gases that produces this difference between the definite surface temperature and the effective temperature is due to the atmosphere. the increased amount of gasses that absorbed heat is advance to had more heat being retained in the atmosphere and can increase the global average surface temperature,not only greenhouse effect that cause climate change the human aspects can also change earth's climate, human activities such as burning fossil fuels and deforestation, and it can be one causing global warming.
