Mass wasting _____. creates deltas and moraines changes the land by plucking is the movement of sediment by gravity transports rock up an incline by sliding or slumping

Answers

Answer:  Is the movement of sediment by gravity.

Mass wasting is the movement of sediments generate due to the mass movement of rock, soil or other debris from a hilly or slopy region downwards due to the effect of gravity. This effect can be highly be observed during landslides. Agents like wind and water also promote this effect.

Mass wasting is the movement of sediment by gravity transports. Meaning the earth’s outer crust is being ‘wasted’ away on a ‘massive’ scale and falling to lower elevations. It is also a type of erosion and can make changes to the side of the mountain.

A temperature of 200°F is equivalent to approximately A. 232°C.
B. 93.3°C.
C. 840°C.
D. 37.8°C.

Answers

C = 5/9 x (°F - 32)

C = 5/9 (200 - 32)

C = 5/9 x 168

C = 37.74 C or to round off 37.8 C
