A mountain is a raised landform area surrounded by flat ground with a large absolute and relative height on the ground. The height of the mountain above the ground is usually 600 meters above sea level, including low mountains, middle mountains and high mountains. Whether it is called a mountain depends on the locals. Mountains are generally created by plate collisions or volcanism. Mountains will slowly erode due to rivers, climate action or glaciers. Some mountains will form a single peak, but most of the mountains will be connected together to form a mountain range. Well-known American mountains are the Appalachian Mountains, the Rocky Mountains, Sierra Nevada, Denali, Mauna Kea, Mount Rainier, Mount Everest, The Himalayas, Table Mountain, Huangshan Mountains, Drakensberg Mountains, Mount Kilimanjaro, Mount Fuji, The Swiss Alps, and etc.
