A hemisphere is half of a sphere, defined in geometry as a 3D shape with one flat circular side and a curved surface, often used to describe Earth’s divisions—Northern/Southern (by the Equator) and Eastern/Western (by the Prime Meridian).
All about the Earth's natural environment, features, and processes, focusing on landforms, climate, soils, water, and ecosystems.
