22. Both folding and uplifting can cause tilting in sedimentary rock.
23. Passive continental margins show rapid accumulation of sediments.
24. Two continents might collide when all the ocean crust between them has subducted under one of the continents.
25. The dip of the limbs of a fold shows the intensity (strength) of the folding process.
26. Mud cracks are wider near the bottom of the layers of overturned rock.
27. Plutonic dome mountains result from volcanic activity below ground.
