Question

according to the theory of plate tectonics, which is one feature that plates carry?
○ seafloor
○ inner core
○ lower mantle
○ asthenosphere

Explanation:

1. Recall the theory of plate tectonics: Tectonic plates are large slabs of rock that make up the Earth's lithosphere (crust and upper mantle). These plates move over the asthenosphere (a semi - molten layer below the lithosphere).
2. Analyze each option:

• The inner core is at the very center of the Earth, far below the tectonic plates, so plates do not carry the inner core.
• The lower mantle is below the asthenosphere and is not carried by the tectonic plates.
• The asthenosphere is the layer on which the tectonic plates move, not something the plates carry.
• The seafloor is part of the oceanic crust, and oceanic crust is part of a tectonic plate. So tectonic plates carry the seafloor.

Answer:

A. seafloor
