Astudent observes rock layers that are folded and appear to be scratched. select all of the geologic forces that might have caused this.

question 10 options:

plate tectonics

glacial advance

magnetic reversal

seafloor spreading

Rock layers are folded and appear to be scratched because of the plate tectonics and the glacial advance.

Option 1 and 2.

Explanation:

Plate tectonics and the glacial advance are the geological phenomenon which have the power to effect the layers of the rock. Because of these, there can be scratches on the layers of the rock and the layers of the rocks can be folded.

The huge mass of ice that is included in the glacier which may be of thickness of three to four kilometers is a lot to scratch the rocks. These glaciers are responsible for moving the rocks from their original position to a new place altogether.
