A hot spot is a place where __________ from the mantle rises to the crust.

• Steam
• Lava
• Magma
• Ice

Why does Iceland have so many volcanoes?

• Volcanoes in Iceland are a result of excessive deforestation
• Iceland is located on the Mid-Atlantic Ridge, a divergent tectonic plate boundary, resulting in many volcanoes due to the movement of the North American and Eurasian plates.
• The high population density in Iceland leads to the formation of numerous volcanoes
• Iceland has many volcanoes because of excessive mining activities
