Answer:
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.

Answer:
Explanation: tellurium has an atomic mass of 127.6 whilst the element that comes after it, iodine, is lighter with an atomic weight of 126.9. Mendeleev concluded that the atomic mass for one of these two elements must be wrong because tellurium clearly preceded iodine in the periodic table
<em>They are based on a carbon molecular structure</em>
Answer:
1.29 M
Explanation:
since it's a dilution, the new concentration must be less than 2.1 M
c1V1 = c2V2
c2 = c1V1/V2 = (2.1 M×215 mL)/350 mL = 1.29 M
