HEL Scientists have several theories about magma hotspots and mantle plumes. They are theories because neither can be observed within the Earth's layers. Scientists say a model of a hotspot/mantle plume location in the Earth is much like a lava lamp. Consider the photo of the lava lamp and complete the analogy. Select which description would not apply.

A) The lava in the lamp represents the magma in the mantle.
B) The outer glass case represents the rigid rock layers in the mantle and crust.
C) The rising lava represents the magma that moves toward the crust via convection.
D) The heating coil in the bottom of the lamp represents the heat energy in Earth's core.
