Question

Now, climb the ramp that leads to the top of the structure. As you climb, determine the age of each rock layer. Do this by aiming the Rock-O-Matic at question marks like the one shown above.

Use the ages to complete the table.

Rock Layer

Age

Layer C4 (reddish brown)

Layer C3 (yellow)

Layer C2 (dark gray)

Layer C1 (light gray)

Answer 1

To determine the ages of the rock layers, typically, you would use relative dating techniques based on the principles of stratigraphy, or possibly radiometric dating if you have specific isotopes to work with. Since I don't have specific information on the ages of these layers, I can provide a general approach based on typical stratigraphic principles:

1. Layer C1 (light gray) - This layer is likely the oldest because it is at the bottom of the sequence.
2. Layer C2 (dark gray) - This layer is younger than C1 but older than C3.
3. Layer C3 (yellow) - This layer comes above C2 and is therefore younger than it, but older than C4.
4. Layer C4 (reddish brown) - This is at the top and is likely the youngest layer.

Now if we have hypothetical ages from the provided answer bank, we could fill in the table like this (hypothetical ages provided as 100 million years, 200 million years, etc.):

| Rock Layer | Age | |------------------|------------------| | Layer C1 (light gray) | 200 million years | | Layer C2 (dark gray) | 150 million years | | Layer C3 (yellow) | 100 million years | | Layer C4 (reddish brown)| 50 million years |

Replace the age values with the actual ones from your answer bank to complete the table.
