What Are Landforms?
Landforms shape the surface of the Earth. Landforms
often serve as geographical boundaries among places.
Where people choose to live is often decided by the
landforms on Earth. Landforms are important because
they separate countries or make movement di cult and
act as natural defenses.

Land covers around one-fourth of the Earth’s surface.
In some places, the land is too high to live in. In other
places, the land is too low. Some land areas are richly
green and others are dry and desolate (a desolate place
is a place that has no people living in).
Egypt has a variety of natural physical features that
shape the country, such as mountains, plains, deserts,
plateaus, rivers, and valleys.
