11
A model of how material is cycled on the Earth would need to include all of the following EXCEPT-
Heat from the Earth's interior.
Position and motion of the Earth.
Radiation from the Sun
Movement of air, water, and rock.
12
Part of the recycling of seafloor material includes its destruction. This happens-
at trenches where rock material is subducted.
when elements in rock are rearranged chemically.
through weathering and erosion of exposed rock layers.
as a result of violent and frequent volcanic activity.
13
These rocks provide evidence of plate movement because, as we look at rocks farther from the ridge, the rocks
become thicker and thicker.
have higher iron conent.
are made up of smaller particles.
are consistently older.
14
When looking at the shape of the continental shelves that surround South America and Africa, they fit. This supports-
the tectonic plates beneath these continents are roughly the same age.
the continental shelves of these two continents are made of the same rock.
the material that makes up these continental shelves comes from sediments.
