Which of the following belts are associated with seismic activity?
1. Circum-Pacific Belt
2. Circum-Atlantic Belt
3. Mid-Continental Belt
4. Mid-Atlantic Belt Correct Answer 1, 3 and 4
The belts associated with seismic activity are Circum-Pacific Belt, Mid-Continental Belt and Mid-Atlantic Belt. Ring of Fire, also called Circum-Pacific Belt or Pacific Ring of Fire, long horseshoe-shaped seismically active belt of earthquake epicentres, volcanoes, and tectonic plate boundaries that fringes the Pacific basin. Mid-Continental Belt is a large volcanically active region. Other terms are used for smaller areas of activity, such as volcanic fields. Volcanic belts are found above zones of unusually high temperature (700-1400 °C) where magma is created by partial melting of solid material in the Earth's crust and upper mantle. These areas usually form along tectonic plate boundaries at depths of 10–50 km. The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent tectonic plate or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.
