Hello, Nadsdsss!! Global warming has occurred due to increase in greenhouse gases, along with many other things. The greenhouse gases include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20). Take CO2 for example, when we emit more CO2 into the atmosphere, it will cause a blanket trapping in the heat from the sun, which will cause heat to increase. With heating the atmosphere comes heating the ocean more and allow glaciers and ice to melt, which will cause sea rise. With both of these happening because of global warming, this causes more hurricanes within the world. Throughout the past few years, there has been a substantial amount of hurricanes that have increased due to global warming. I hope I helped!! If you have any more questions then feel free to message me and I will answer them for you. Have a great day.
the answer is B. Stratovolcano
Stratovolcano is composed by one layer of hardened lava, volcanic Ash, and Tephra
These volcanoes are identified by their periodic explosive eruption, spitting highly viscous lava that could spread in a far distance
I would look at the key on the map
