Question

which concept includes the idea that the earth’s surface is broken into many pieces?
○ seafloor spreading
○ plate tectonics
○ continental drift
○ pangea

Explanation:

• Seafloor spreading refers to the formation of new oceanic crust at mid - ocean ridges, not about the Earth's surface being broken into pieces.
• Plate tectonics is the theory that the Earth's lithosphere is divided into several large and small rigid plates (pieces) that move relative to each other.
• Continental drift is the idea that continents move over the Earth's surface, but it doesn't focus on the Earth's surface being broken into pieces.
• Pangea was a supercontinent, not a concept about the Earth's surface being broken into pieces.

B. plate tectonics
