The Earth is divided into three main layers based on the differences in the chemical properties of its constituent materials: the crust, mantle, and core.
Solar System
Astronomy has always been one of the subjects of human interest that especially children and teenagers are attracted to this subject.
Rock Cycle
In geology, the rock cycle constitutes a foundational conceptual model that elucidates how lithologic materials evolve across geological time through the interplay of tectonic processes, sedimentation, erosion, and metamorphism.
Sundial
A sundial is a device that measures local time during the day by using the position of the sun in the sky. The most common type of sundial consists of a rod (gnomon) placed on a flat surface, with the hours of the day marked on the surface. As the sun’s position in the sky changes, the shadow cast by the rod moves across the surface, indicating the time.
