Answer:
Deforestation
Explanation:
Deforestation is the primary environmental cost of Southeast Asia's dominance in exports of rubber and palm oil.
Deforestation is the permanent removal of trees to make room for something besides forest and this occurs in the Southern Asia to make room for Rubber and palm oil which are significant in Malaysia, Indonesia, and southern Thailand etc.
Demand for these commodities cause the environmental concerns over deforestation as the main concern in Southern Asia.
Deflation is a process of erosion by wind which leaves desert pavement behind.
Metamorphic rocks are produced when rocks are recrystallized by heat and pressure.
Although they began as a different kind of rock, metamorphic rocks have undergone significant alteration from their igneous, sedimentary, or previous metamorphic forms. When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some combination of these conditions, metamorphic rocks are created.
High pressures and temperatures both have a role in recrystallization. Solid crystals can reorganize themselves by migrating as a result of high temperatures. The crystals within the rock at their places of contact dissolve under high pressure.
