the earth.
The motion of the tectonic plates: The pieces of the surface of the earth shifting
around and bumping into each other can cause sections of earth to be forced
upward, such as in the Himalayas.
• What: A Mountain is a large landform that stretches above the
land in a area usually in the form of a peak.
