Answer:
Q. 41. Basaltic Lava, Q.43. Basaltic magma Q.44. False
Explanation:
Basalt is a mafic extrusive igneous rock, formed by the rapid cooling of Mg and Fe rich lava, exposed at or near the surface of the earth. Thus forming about 90% of the surface lava on earth.
Shield Volcanoes emit lava or magma in the form of viscous basaltic lava. Highly explosive.
Greenland and Antarctica together constitute the 99% of the earth ice caps so, Greenland has about 80% cover as compared to antarctic 98% and both are depleting fast.
Agriculture can prove extremely difficult to maintain on a rocky mountain and with such poor infrastructure it is also difficult to import goods on a JIT (Just In Time) sort of basis where you receive these goods as you need them. Infrastructure also includes communication and other services and with such a technologically developed era we depend on technology and this can deter a lot of people from settling in these regions, additionally the wildlife in these regions consists greatly of predators which can be deemed a threat to habitants who are unprepared. The sheer abundance of wildlife and non industrial landscapes can also mean that people will not want to live in these regions
