Explanation:
The majority of the volcanoes that form at subduction zones, or convergent plate boundaries, are stratovolcanoes. These volcanoes are also called composite volcanoes. The stratovolcanoes are known to have high to intermediate silica content of the lava they release. The eruptions tend to be periodic, and they are explosive and effusive in general, though there are exceptions. The fact that the lava is high to intermediate in silica content means that the lava is medium to highly viscous. Because of this, the lava tends to trap the gases in it, and as it reaches the surface and the temperature and pressure sharply change, the gases explode, resulting in eruptions that have lot of explosions and propelling of pyroclastic material.

An expansive pyramid age-structure diagram best displays the age ranges in a country that is in stage 2 of the demographic transition.
Option d
<u>Explanation:</u>
The shift in demographics from high death rates and high birth rates in societies with lower education, technologies and economically under developed to demographics of low death or birth rates in societies with advanced technology, higher education and persistent economic development and includes the stages between both the scenarios stated is named as demographic transition.
This is to suggest or evaluate the growth rate cycles of the population of the country. There are 3 types of population pyramids namely,
Expansive population pyramids - shows the population that has the greater percentage in younger age groups. Most of the 3rd world nations fall in this category.
Constrictive population pyramids - shows declining birth rates
Stationary population pyramids - depicts equal proportion of population in all age categories.
