Yes, Mercury has both valleys and mountains. Some of its valleys were likely formed by tectonic activity, while its mountains are thought to be the result of volcanic activity. Mercury's surface features are the result of a combination of tectonic forces and volcanic processes.
Mercury's surface is characterized by a mix of craters, valleys, and rugged terrain. The planet is heavily cratered due to its lack of atmosphere, which allows impacts to remain preserved over billions of years. Notable features include the Caloris Basin, one of the largest impact craters in the solar system, and the extensive system of lobate scarps, which are cliffs formed by the planet's contraction as it cooled. Valleys on Mercury, such as the smooth plains known as "intercrater plains," are often found in between these craters and scarps.
It appears to have many rocky valleys and ridges, and innumerable impact craters.
The plural form is valleys.
There are several types of valleys, including V-shaped valleys formed by erosion from rivers, U-shaped valleys carved by glaciers, rift valleys formed by tectonic activity, and hanging valleys created when smaller tributary valleys flow into larger main valleys.
Mercury, Venus, Earth, and Mars are the inner planets that have rocky surfaces. These planets are primarily composed of silicate rocks and metals, with solid surfaces that range from cratered and mountainous terrains to volcanic plains and valleys.
