1. what is the “engine” or force that causes the huge plates of the earth’s crust to move?

b) the sun
c) airplanes
d) earthquakes

1. what do scientists call the ancient “supercontinent” that existed hundreds of millions of years ago, before the continents split apart?

a) atlantis
b) laurasia
c) gondwana

Explanation:

• For question 2: Fossils and rocks matching across different continents are strong evidence for continental - drift theory, indicating they were once joined. Volcanoes, weather, and current animal distribution are not strong evidence.
• For question 3: Plate tectonics is the theory that describes the movement of Earth's crustal plates. The Sun, airplanes, and earthquakes are not the 'engine' for plate movement.
• For question 4: Pangaea was the ancient supercontinent. Laurasia and Gondwana were parts of Pangaea after it started to break up, and Atlantis is a mythical continent.

Answer:

1. C. Fossils and rocks that match up across different continents
2. A. Plate Tectonics
3. (No correct option given in the choices as the correct answer is Pangaea)
