From oldest to youngest: I, B, F, M, R, H.
Explanation:
On the picture we can see several layers of rock. Some of the layers have not been disturbed, so the principle of superposition can be applied to them. Some of the layer though have been disturbed by geological processes, so the layers are not at the same level because of it. On top of it, there is also an intrusion that has managed to further cause disturbance through all of the layers.
- The layer I is the oldest, and it is the basis of the others.
- Layer B has formed next, and after that layer F.
- These three layers have been influenced by the formation of fault, where one of their sides has been moving up relative to the other, while the other has been moving down relative to the other.
- Layer M is younger layer, and it can easily be seen as it totally covers the layer F below it.
- On top is layer R, which is the youngest of them all (the layers), and the one that comes out on the surface.
- Layer H is not really a layer, but it is an intrusion, which has formed after magma managed to cut through all the layers and later solidify. It is the youngest formation.

Answer:
[a] 103m (I guess that it is 10^3 m)
Explanation:
To calculate how many millimeters you enter in a kilometer, just know the relationship between both units of distance.
The relationship is as follows:
1 km = 1 000 000 mm
So:
1 km = 1000 m = <u>10^3 m</u> = 10^6 mm = 1 000 000 mm
In geology, a graded<span> bed is one </span>characterized by<span> a systematic change in grain or clast size from one side of the bed to the other. Most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into progressively finer ones.</span>
The answer is A, Thomas Jefferson. Hope this helps.
