Fossils of trees were discovered in a sedimentary rock layer, and in a rock layer below were fossils of clams. Based on this evidence, what conclusion can be made about the sequence of climates in the past in the area where the fossils were discovered?
Based on the evidence, it can be assumed that this area was an underwater forest.
Based on the evidence, it can be assumed that this area was a forest before it was a beach or ocean.
Based on the evidence, it can be assumed that this area was an ocean or beach before it was a forest.

Continental Drift Theory
Plate Tectonic Theory
Seafloor Spreading
Convection Current
Over long periods of time, one plate slips underneath another plate, which created a trench. As the one plates slips deeper into the mantle, it begins to melt. Does this scenario describe constructive forces, destructive forces, or both?
Destructive: When seafloor spreading occurs, part of the ocean floor is destroyed.
Constructive: When subduction occurs, new crust can be made.
Both: Seafloor spreading occurs, where old crust is destroyed and new crust is created.
Destructive: When subduction occurs, the bottom plate melts, which destroys the crust.
