Write a brief summary describing oceanic ridges.
 
  What will be an ideal response?

Question 2

The primary cause of Earth's seasons is:
 
  A) changes in atmospheric thickness.
  B) varying distance from the Sun, which changes how much radiation Earth receives from the Sun.
  C) varying orbital speed.
  D) tilt of Earth's rotation axis, which causes sun angles and daylight length to vary.
  E) regular changes in radiation emitted by the Sun.

Answer to Question 1

The oceanic ridge system winds through all major oceans in a manner similar to the seam on a baseball and is the longest topographic feature on Earth, exceeding 70,000 kilometers in length. The crest of the ridge typically stands 2 to 3 kilometers above the adjacent deep-ocean basins and marks the divergent plate boundary where new oceanic crust is created. The term ridge is somewhat misleading because these features are not narrow and steep as the term implies but have widths of from 1000 to 4000 kilometers and the appearance of broad, elongated swells that exhibit varying degrees of ruggedness. Furthermore, the ridge system is broken into segments that range from a few tens to hundreds of kilometers in length. Each segment is offset from an adjacent segment by a transform fault. Along the axis of some segments of the oceanic ridge system are deep, down-faulted structures called rift valleys that are typically 30 to 50 kilometers wide and have walls that tower 500 to 2500 meters above the valley floor.
