The common among the pictures is the formation of divergent plate boundary, where it forms the rift valleys and oceanic ridges.Explanation:
The indication that the plate is spreading or splitting apart is the the formation of Rift Valleys and Oceanic Ridges. Divergent plate boundaries are mostly situated in along underwater mountain ranges called Oceanic ridges. Once the plate separated, new materials from the mantle appears and fill up the gaps, producing new ocean floor.
Great example of oceanic ridge is Mid-Atlantic Ocean ridge that caused the divergence of the African plate and the South American plate.
Meanwhile, due to the spreading center develops within a continent, the plate may break into segments. The breaking then produced faulted valleys called rift valleys.

Q28: each pictures has a fracture or crack on its land masses.
Q29: The earth's crust is moving away to each other very slowly or 3-10 cm per year.
Q30: If this event continues to move for another million of years the crack will become wider and wider that it would cause to form a Riff Valley.
Q31: the answer is on page 28 figure 20.

Q29. the crust of the earth's being eroded by water, creating canyons and valleys on the surface and trenches on the seafloor
Q30. the earth would have numerous depressed (or lowly elevated places) like canyons, valleys and trenches.
Q31. draw a sectional drawing of a canyon, valley or trenches to show the lowly elevated part with relation to the highly elevated part or its nominal elevated level before becoming a canyon, valley or a trench.
