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).
Most of India falls within the monsoon climate (south and west India) but the wider locations within India include very different characteristics. South and West India has a typical tropical monsoon-based climate.There is heavy rain almost continuously in the months of June, July, August and September.The South-west Monsoon winds first hit the Western coast from the Arabian Sea. They continue traveling towards the north-east, till they dry out.outh and West India has a typical tropical monsoon-based climate.
