Global Patterns Climate patterns involve complex interactions between Earth's atmosphere, oceans, land surfaces, and ice masses. These systems work together in intricate ways, creating both short-term weather events and long-term climate trends. Ocean currents play a crucial role by distributing heat around the planet, while atmospheric circulat

Molecular Structure DNA (Deoxyribonucleic Acid) serves as the fundamental building block of human life, containing the genetic instructions that make each person unique.
