In today’s lesson, we discussed geology, focusing on the internal structure of the Earth and its properties. We learned that the Earth consists of several layers, including the solid inner core, the liquid outer core, the mantle, and the outer crust where we live. The mantle is responsible for volcanic activity and earthquakes, while the crust contains all life forms, oceans, and atmosphere. Geologists study these layers to understand the Earth’s structure, which is essential for activities like building infrastructure.
