Result
Your answer: —  Â·  Correct: D
Explanation

Tectonic activity in Iceland, driven by its location on the Mid-Atlantic Ridge and a mantle hotspot, provides significant advantages. First, it is a major source of natural geothermal energy; Iceland is a global leader in harnessing steam and hot water from underground to heat homes and generate electricity [3]. Second, the divergence of the North American and Eurasian plates allows magma to rise, creating new crust and landmass through fissure eruptions and lava flows [4]. Third, these geological features, including active volcanoes, geysers, and hot springs, serve as major tourist attractions that draw international visitors. The interaction between the spreading plate boundary and the mantle plume has uplifted the basalt plateau and continues to shape the island's dynamic landscape [1]. Thus, all three statements correctly identify the benefits of Iceland's unique tectonic setting.
