Question 9
Using the concept of the Earth and the solar system, explain the process of plate tectonics and its role in shaping the Earth's surface, and identify the most significant geological feature in Nigeria.
A. Plate tectonics is the process by which the Earth's lithosphere is broken into plates that move relative to each other, resulting in the formation of mountains, volcanoes, and earthquakes.
