The steepness of slopes on a volcanic mountain is determined primarily by: the relative amounts of pyroclastic debris and lava erupted from the volcanic vent. the initial temperature of the lava. the amount of rainfall in the area. the force with which the magma is pushed upward. none of these.
The South Asia subregion spans seven countries (Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka).[39] The areas of these countries vary from 30 000 ha (Maldives) to 297 319 000 ha (India).his subregion has a negative rate (0.13 percent per annum) of forest cover change, which is roughly double the negative rate of change for the Asia region (0.07 percent per annum) but is roughly half the negative rate (0.22 percent per annum) of change for the world (Table 23-1).
