Flashcards: Understanding Earth's Dynamic Layers — 10 cartões

Plate Tectonics — what causes surface features?

Movement of Earth's lithospheric plates.

Historical Development — key evidence?

Seafloor spreading and paleomagnetic data.

Seafloor Spreading — process?

New crust forms at divergent boundaries.

Subduction Zone — role?

One plate sinks beneath another.

Plate Boundary Types — examples?
