Primarily, as the economy improves, more individuals can afford to send their children to school.
The movements of tectonic plates drive geologic activity on Earth, serving as the primary mechanism behind the formation of surface structures. Due to the ongoing motion of these plates, adjustments within the Earth's crust take place, resulting in a build-up of pressure (both vertical and lateral), and forcing magma toward the Earth’s surface, which leads to the alteration of the landscape. Some changes occur over millions of years, while others happen rapidly, ultimately resulting in new geological features such as hills, mountains, valleys, volcanoes, and rifts.
The ocean floor remains largely uncharted due to the difficulty of accessibility without appropriate equipment.
