What is a mountain that looks like rounded hill?

A mountain that looks like a rounded hill is called a dome mountain. Dome mountains are typically formed by the erosion of volcanic domes, which are mounds of lava that have been extruded from a volcano. Over time, the lava cools and hardens, and the volcano becomes dormant or extinct. The lava dome may then be eroded by wind, rain, and ice, forming a rounded hill.

Dome mountains are often found in volcanic regions, such as the western United States, the Andes Mountains, and the East African Rift. Some well-known dome mountains include Mount Shasta in California, Mount Kilimanjaro in Tanzania, and Mount Elbrus in Russia.

Dome mountains can be a variety of different sizes, from small hills to large peaks. They can also be found at a variety of elevations, from sea level to high altitudes. Some dome mountains are covered in vegetation, while others are barren.

Dome mountains are often popular for hiking, climbing, and other outdoor activities. They can also be used for grazing livestock or for growing crops.
