Earth and Beyond

The video tutorial explores the concept of Earth and its representation on a globe, highlighting the imaginary lines used for geographical demarcation. It delves into the structure of Earth, emphasizing the crust as the habitable layer. The tutorial explains gravity, its role in keeping objects grounded, and contrasts life on Earth with life in space, where gravity is absent. The experiences of astronaut Sunita Williams are used to illustrate the effects of zero gravity in space.
