Answer:

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.

What latitudes are most likely to see glaciers??  
olga55 [171]

Answer : Option D) 90°N and 90°S

Explanation : The latitudes which are given in the options are the angle to be measured in the direction of north and south respectively taking equator as the central line.

When it is 90°N and 90°S it means it forms an right angle and faces towards north and south respectively with respect to the equator, so there are high chances of pointing towards the Arctic and Antarctic regions respectively; therefore giving greater probability of finding glaciers.
