Which of the following is NOT a major tectonic plate?

• African Plate

• Antarctic Plate

• Pacific Plate

• Arctic Plate

How did they discover that the tectonic plates had moved? Was that movement related to Earth structures such as mountains, valleys, or volcanoes?

• Through the study of fossil distribution and matching geological features across continents.

• By observing the daily movement of tectonic plates using satellites.

• Through the analysis of ocean currents and their impact on climate.

• By measuring the temperature changes in the Earth's core.

Look at the world map and notice the shapes of the continents. Do you see how some continents appear to fit together like the pieces of a jigsaw puzzle? Why do you think this is? Is it just a coincidence, or do you think it suggests something important about the history of our planet?

• It is just a coincidence.

• It suggests that continents were once connected.

• It is due to the current shape of the Earth.

• It is because of the way maps are drawn.
