adaptation is what's happening, and the moths changed color to adapt to the new environment.
because of the smoke, the light colored moths were easily spotted and eaten. but they changed color over time to account for that, turning black to make them harder to spot and eat.
Landslide is a general term referring to all types of surface movement, like avalanches involving the mass movement downhill of soil, rock, or snow under the action of gravity. These can be dangerous to human life.
Mudslides are caused unusually heavy rain or sudden thaw. they consist of mostly mud and water with fragments of rock and other debris. They're capable of moving house off of their foundations and can bury a place within minutes.
Mountain slopes have faster erosion because it is easier for fast moving bodies of water to carry down eroded material downhill, rather than across flat land.
Assuming it's only salt water, it should be 85%
One way is that Igneous rock could erode and become sediment and deposited and slowly change into sedimentary rock, then get pushed down deep into the crust and changed by heat and pressure into metamorphic rock.
