Science is broadly categorized into several major branches, each focusing on different aspects of the natural world. The primary branches include physical sciences, which encompass physics and chemistry, studying matter and energy; life sciences, which include biology and ecology, focusing on living organisms and their interactions; and earth sciences, which cover geology, meteorology, and oceanography, examining the Earth and its processes. Additionally, applied sciences such as engineering and medicine utilize scientific principles to solve practical problems. Each branch contributes to a comprehensive understanding of the universe, often intersecting and collaborating to address complex questions and challenges.
