Explanation:
Q 1). Give a critical explanation of Gaseous hypothesis of Kant regarding the origin of Earth
ANS = Kant postulated his gaseous hypothesis of the origin of the earth on the basis of a few assumptions. He assumed that supernaturally created primordial hard matter was scattered in the universe. ... He further argued that the random motion of the particles also generated rotatory motion in the primordial matter.
Q2). Define volcanism. What are the different types of volcanoes of central eruption? Enhance your answer
ANS = In general, eruptions can be categorized as either effusive or explosive. Effusive eruptions involve the outpouring of basaltic magma that is relatively low in viscosity and in gas content. ... Volcanic eruptions may fall into six major types: Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian.
