Landscapes
Let’s
compare

ESRT’s.

Landscapes are divided into 3 groups:
1. Mountains/Highlands – areas of steep gradient and
high elevation. These areas have thin, steep
rivers/streams with a very high velocity. They also have
thin soil and areas of exposed bedrock.

2. Plateaus/Uplands - areas of high elevation, that have
a horizontal (flat) surface. These areas are surrounded by
steep slopes. The rivers/streams on plateaus/uplands
flow slower than the rivers/streams in the mountains
because the land is flatter. Soils are thicker on plateaus.

3. Plains/Lowlands – areas that are completely flat or
have only small hills. The streams/rivers have low
velocities because there are no slopes. The streams
and rivers also tend to meander (curve). The soils in
the plains are very thick and support a lot of farming.

There are 2 types of natural forces that influence the rate
at which landscapes develop:
1. Uplifting forces – forces that cause the Earth’s crust to raise
up. Mountain formations and volcanic eruptions are examples
of uplifting forces.
2. Leveling forces – forces that breakdown and lower the surface
of the Earth. Weathering and erosion are examples of leveling
forces (weather breaks down the Earth). Gravity is also a
leveling force.
Leveling forces are always at work on the Earth’s surface.
However, uplifting forces are not always occurring.

Label the diagram with the following terms: Highlands, Uplands, or Plains &
Youthful, Mature, or Old Age
