Surface features refers to physical characteristics or structures that are present on the surface of a planet, moon, or other celestial body. These features can include mountains, valleys, craters, plains, ridges, canyons, and other formations that are visible on the surface. Surface features provide important clues about the geological history and processes that have shaped a planetary body. Scientists study surface features to understand the formation and evolution of planets, moons, and asteroids, as well as to learn more about the composition and dynamics of their interiors. Researchers use a variety of tools and techniques to study surface features, including remote sensing data from satellites and spacecraft, as well as field observations and laboratory analysis of rock samples. By analyzing surface features, scientists can gain valuable insights into the geological processes that have sculpted the surfaces of planets and other celestial bodies in our solar system and beyond.
