The image below shows the Lake Mead Recreation Area, which is near the Grand Canyon The diagram shows the
ages of layers of rock in one region of the park, The layers
at this location are fairly smooth and distinct
Private
What are these smooth, distinct layers most directly evidence of?
A Soll creep along the rocky cliffe
B. Many landslides and mudslides
6. Extensive chemical weathering
D. Many, many years of deposition

D. Many, many years of deposition

Explanation:

The layers of the rocks in one region of the parks are smooth and distinct, which are evidence of many, many years of deposition.

The layers on the rocks are because of different deposition of sediments. Different sediments deposited over the rocks through wind, water and ice over the ages.

Hence, the correct answer is D.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
