question 35

Multiple Choice

Which statement is true about the lithosphere?

• A) The lithosphere is thickest at the mid-ocean ridges because of the quantity of magma that flows up to the surface.
• B) The lithosphere gets thicker as distance from the ridge increases, because it cools and the boundary between the lithosphere and asthenosphere occurs at greater depth.
• C) The lithosphere maintains its thickness as distance from the ridge increases, because the boundary between the lithosphere and asthenosphere remains at a constant temperature and depth.
• D) The lithosphere gets thinner as distance from the ridge increases, because decompression melting occurs with decreased pressure.
