Question

the diagram below is of the lithosphere (the crust) on the earths surface. the lithosphere sits on top of the mantle, which is hot molten rock, and a convection current in the mantle causes the earths lithosphere to move. activity 1 of 2 based on the diagram, which letter indicates a place where new plate material is forming? a. x b. y c. z activity 2 of 2 develop a claim stating where the source of material comes from to form the new plate. claim:

Explanation:

• For Activity 1: At divergent plate boundaries (where plates move apart), new plate material forms. In the diagram, if we assume the standard plate - movement logic (plates moving apart at a mid - ocean ridge - like structure), the area where new material forms is at the boundary where plates are separating. If \(Z\) is the mid - point between two plates moving apart (similar to a mid - ocean ridge), new material wells up from the mantle to form new crust.
• For Activity 2: According to the theory of plate tectonics, the source of new plate material is the mantle. Mantle convection currents bring hot, molten rock (magma) to the surface at divergent plate boundaries. As the plates move apart, the magma cools and solidifies to form new oceanic crust (plate material).

Answer:

• Activity 1: C. \(Z\)
• Activity 2: The source of material to form the new plate comes from the mantle.
