During mass wasting/mass movement rocks fall because gravity and then build up at the base of the cliff

Explanation:

Weathered materials are moved by forces of gravity from a higher place to a lower one.Some occurs sudden with adverse effects such as landslides while some movements are less dramatic such as slump and creep movements that move materials slowly to the bottom of a hillside.In mass wasting, weathered material experience less forces holding them causing them to fall to the base of a cliff forming a talus slope.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
