Answer:
snowmobiles
Step-by-step explanation:
Snowmobiles are a popular mode of transportation used by scientists and researchers to explore Antarctica today. They are faster than dog sleds and can cover more ground in less time. Snowmobiles can also carry heavier loads, making them more efficient for scientific expeditions. However, the use of snowmobiles in Antarctica is also controversial, as they can harm the fragile environment and wildlife. Some areas of Antarctica are designated as protected zones, where snowmobiles are prohibited, and scientists and researchers are required to use alternative modes of transportation, such as skis or snowshoes. Overall, while snowmobiles have proven to be a valuable tool for exploration and research in Antarctica, they must be used responsibly to minimize their impact on the fragile Antarctic environment.
