Mount Merapi is a stratovolcano, which means it has steep sides built by many layers of volcanic rock! ๐
๏ธ It is made up of lava flows, ash, and volcanic rocks that have spilled out during eruptions over time. The volcano is located in a very seismic area, which means it experiences lots of earthquakes, making it very active! Merapi's last big eruption was in 2010. Its eruptions create a special land called โlahar,โ a type of mudflow that can happen when heavy rain washes volcanic ash down. The layers of history in Merapi's rocks tell us about the Earth's past! ๐
