5 important questions on Areas with magmatic rocks

Main division in magmatic rocks, think about the volcanoes from which they originate.

Intrusive and extrusive

What could be results due to acid precipitation (I guess due to a volcanic eruption). *Note: not sure about the quality of this flashcard (need to check lecture for this).

Physical weathering ('tor') and dead forest

What do they do in India to conserve water in areas that consist of magmatic (intrusive) rock? *Note: not sure about the quality of this flashcard (need to check lecture for this).

Name an intrusive rock relevant to areas with magmatic rocks

Intrusive: granite

Name several relevant morphological features of extrusive rocks from areas with magmatic rocks

Scrambled egg layer on top of lava flows
Pyroclastic layers
Paleosols
Dikes (small intrusive layers, look vein-like) which allow water flow and may result in springs at the surface.

Especially the paleosol - lava flow - scrambled egg layer occur often in this sequence, followed by a potential new sequence.
