Physical Environment: The physical environment refers to everything around us that is non-living. It includes:
Air -atmosphere, Water -rivers, oceans, rain, Land -soil, rocks, mountains, Climate and weather, Natural features like sunlight, temperature, wind
In short:
The physical environment is the natural world we live in, minus the living things. It affects how people, animals, and plants live.
Chemical Energy: Chemical energy is a type of stored energy that is found in the bonds between atoms and molecules. When we burn wood, gasoline, or food, the chemical bonds break and release energy as heat, light, or movement. Our bodies use chemical energy from food to move, grow, and stay warm. Batteries store chemical energy and release it as electricity.
In short: Chemical energy is energy stored in substances, and it’s released during chemical reactions—like digestion, burning fuel.
