6. PLAINS
Places that are not so rugged and
are not much higher than sea level
are called plains. Based on their
formation, they have been divided
into three. Structural plains,
erosional plains and depositional
plains.
7. STRUCTURAL PLAINS
Due to endogenic forces, an area can be
raised or lowered. These actions are called
uplift and subsidence respectively. These
actions cause plains to be formed. They are
called structural plains.
8. EROSIONAL PLAINS
Some areas on the earth’s surface which
originally were rugged are leveled due to
friction or plantations. This is possible
due to the action of several agents. The
plains that are formed thus are called
emotional plains.
9. DEPOSITIONAL PLAINS
Running water, winds, glaciers, sea waves,
and other external agents carry rock materials
from the hills to depressions on the surface of
the earth or to the water bodies. In course of
time these deposits lead to the formation of
plains.
