Which of the following statements concerning circum-pacific belt are correct? 1. It is an active volcanic realm 2. It is an active seismic realm 3. It is a divergent plate boundary 4. It is prone to Tsunami Select the correct answer using the code given below:
Explanation
The circum-Pacific belt, or 'Ring of Fire', is the most volcanically and seismically active zone in the world [3]. It contains over 70 percent of the world's active volcanoes and experiences 90 percent of Earth's earthquakes [1]. This belt is primarily characterized by convergent plate boundaries (subduction zones), where oceanic plates collide with and slide beneath other plates, creating deep trenches and rising magma [3]. Because it is a convergent boundary, statement 3 is incorrect as it is not a divergent boundary [3]. Furthermore, the intense seismic activity and subduction processes along the Pacific margins make the region highly prone to tsunamis, which are often triggered by powerful undersea earthquakes common at these boundaries [5]. Therefore, statements 1, 2, and 4 are correct, while statement 3 is false.
