planetary surfaces

Planetary surfaces refer to the outer layers of planets, moons, and other celestial bodies. They can vary widely in composition and appearance, influenced by factors like geological activity, impact craters, and atmospheric conditions. For example, Earth has diverse landscapes including mountains, oceans, and deserts, while Mars features dusty plains and volcanic regions. Some surfaces are smooth and young, while others show signs of ancient erosion. Studying these surfaces helps scientists understand a body's history, climate, and the potential for life, as well as informing future exploration and resources for human use.
