Mountains can be formed by erosion!

Wind and water are two of the primary agents in erosion. The Grand Canyon was formed by water erosion by the Colorado River over 17 million years.
Some common surface features formed by water erosion include valleys, canyons, river channels, and waterfalls. Water erosion can also create features like meanders and deltas in river systems, as well as coastal cliffs and caves along the coastline.
Sea caves, sea arches, and sea stacks are three cliff features that may be formed by wave erosion.
Erosionally formed features include valleys, stream and river channels, lake beds, sand dunes, all glacially formed features such as eskers and moraines, seaside cliffs and beaches, canyons, mesas, spires, buttes, caves, and deltas, among others.
Land features formed by gravity erosion include cliffs, rockfalls, landslides, talus slopes, and scree fields. These features are a result of the constant downward pull of gravity causing erosion and movement of rocks and sediment downslope.
Glacial Erosion formed Yosemite Valley and the Sierra Nevada
Some shoreline features formed by erosion include sea cliffs, sea arches, sea caves, and wave-cut platforms. Erosion by waves, currents, and wind gradually wears away the coastline, shaping these distinctive landforms over time.
Deltas are formed by constructive erosion.
Gravity erosion forms features such as cliffs, valleys, and slopes. These features are the result of gravitational forces pulling rocks and sediment down slopes over time, shaping the landscape.
