2. What is the associated resources?Geothermal energy, fertile soils, mineral deposits, building materials
3. Why do volcanoes erupt near plate boundaries?At convergent or divergent plate boundaries, the movement of plates melts rock, creating magma that rises and erupts.
4. How can a volcano be dangerous to people?Volcanoes can send lava, ash, gas, and fast-moving mudflows that can destroy homes and hurt people.

Subduction: The process where one tectonic plate slides beneath another.
Decompression Melting: Melting of rock due to a decrease in pressure, common at divergent boundaries.
Stratovolcano: A tall, conical volcano built up by many layers of hardened lava and ash.
Shield Volcano: A broad, gently sloping volcano formed by successive lava flows.
