Which of the following doesn’t describe Continental Drift Theory?

• All of Earth’s continents were once part of a single landmass called Pangaea.

• Fossils of similar organisms across widely disparate continents proves this theory.

• Scientists did not accept this theory as it lacks the mechanism for how it works.

• States that that pieces of Earth’s lithosphere are in constant motion, driven by convection currents in the mantle.

2. Which of the following doesn’t describe Plate Tectonics Theory?

• It is a theory that describes the features and movement of Earth’s surface in the present and in the past.

• Earth’s lithosphere is composed of different plates and they began to move a long time ago.

• The presence of seven major continents and small islands  is a proof of this theory.

• The occurrence of similar plant and animal species around the shores of different continents proves this theory.

What  makes the plates move?

• Plates move because of the intense heat in the Earth's core that causes molten rock in the crust to move.

• Plates move because of the intense heat in the Earth's core that causes molten rock in the mantle to move.

• Plates move because of the intense heat in the Earth's crust that causes molten rock in the core  to move.

• Plates move because of the intense heat in the Earth's mantle that causes molten rock in the core to move.
