Quartzite is a hard, non-foliated metamorphic rock. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of iron oxide (Fe2O3). Other colors, such as yellow, green, blue and orange, are due to other minerals. Which of the following sedimentary rock forms Quartzite?

Most of the regions near the volcanic areas are densely populated. What could be the reasons for it?
When a volcano erupt, the thrown out materials like steam, gaseous sulfur compounds make the area fertile for agriculture
When a volcano erupt, the lava comes out on the Earth's crust; which has high amount of minerals in it. The land becomes fertile for agriculture.
Ash, cinder,blocks,pumice materials are thrown out of a volcano when erupted they make the land fertile for agriculture.
As a volcano erupts, the Earth's crust is exposed to gases which are releases into soil and groundwater which makes the land fertile for agriculture
