Question

8 according to this principle if one geologic feature cuts across another feature, the feature that it cuts across is older.
a superposition
b original horizontality
c lateral continuity
d inclusions
e cross - cutting relationships
9 according to this principle if one rock contains pieces of another rock, the rock containing the pieces is younger than the pieces.
a superposition
b original horizontality
c lateral continuity
d inclusions
e cross - cutting relationships
10 according to this principle most rock - forming materials are deposited in horizontal layers.
a superposition
b original horizontality
c lateral continuity
d inclusions
e cross - cutting relationships

Explanation:

1. The principle that if one geologic feature cuts across another, the feature being cut across is older is cross - cutting relationships. Cross - cutting features like faults or intrusions are younger than the rocks they cut through.
2. The principle that if one rock contains pieces of another rock, the rock containing the pieces is younger than the pieces is the principle of inclusions. The inclusions are older and were incorporated into the younger rock.
3. The principle that most rock - forming materials are deposited in horizontal layers is original horizontality. This is based on the idea that sediments settle under the influence of gravity in horizontal planes.

Answer:

1. e. Cross - cutting relationships
2. d. Inclusions
3. g. Original horizontality
