Give a geographical reason for each of the following:

(i) Many volcanoes are found along plate boundaries.
(ii) Volcanic mountains are the most diverse mountains in the world.
(iii) Hot springs have medicinal properties to cure skin diseases.

(i) Many volcanoes are found along plate boundaries because when tectonic plates slide past each other or collide against each other due to intense heat inside the earth's core, their edges produce faults along the lines of weakness. It is along these plate boundaries that the crust is weakened and through which the hot magma gushes out leading to volcanic eruptions.

(ii) Volcanic mountains are the most diverse mountains in the world because there are great differences in volcanic eruptions as well as materials they throw up.

(iii) Hot springs have medicinal properties to cure skin diseases since they are a rich source of sulphur.
