Identify the correct statements with reference to landforms and plate-tectonics.
A. The violent volcanoes of South America are associated with ocean-continent convergence.
B. The Himalayas originated due to continent-continent convergence.
C. Hot spots are always located at place boundaries.
D. Earth’s persistent magnetic field is caused by the movement of molten metal in the inner core.
Choose the most appropriate answer from the options given below:

Correct option is D

The violent volcanoes of South America are associated with ocean-continent convergence. This statement is correct. The Andes mountain range, including its volcanoes, forms due to the subduction of the oceanic Nazca plate beneath the South American plate, an example of ocean-continent convergence.
The Himalayas originated due to continent-continent convergence.This statement is correct. The Indian plate colliding with the Eurasian plate caused the formation of the Himalayas, one of the most prominent examples of this type of convergence.
Information Booster:
· Ocean-continent convergence leads to mountain formation and volcanic activity.
· The Himalayas are a prime example of continent-continent collision.
· Hot spots like Hawaii occur far from plate boundaries.
· Earth's magnetic field results from convection currents in the outer core.
· Plate tectonics drive landform development through convergent, divergent, and transform boundaries.
Additional Knowledge:
· Hot spots are always located at place boundaries. This statement is incorrect. Hot spots are not always located at plate boundaries. Hot spots, such as the Hawaiian Islands, can occur in the middle of tectonic plates due to mantle plumes.
· Earth’s persistent magnetic field is caused by the movement of molten metal in the inner core. This statement is incorrect. Earth’s persistent magnetic field is caused by the movement of molten metal in the outer core, not the inner core.
