Aim: How are landscapes defined?Do Now: Try to define the following vocabulary terms in your own words or try to give descriptions of what
these landscapes look like.
1) Plains 2) Plateau 3) Mountain
I. Landscapes (Regions):Landscape – an area on Earth’s surface
that has been affected by uplifting and weathering/erosional forces.
Canadian Rocky Mountain Park, British Columbia
Great Plains, Nebraska
Dynamic Equilibrium
No change occurs because opposite forces are equal.
Landscapes: Erosion = Uplifting
Water Cycle: Precipitation = Evaporation
Can you think of any other situations that are in DYNAMIC
EQUILIBRIUM?
Words You Should Know
Relief
Gradient
Elevation of an area
Steepness of the land
Try this: A hiker climbs to the top of a mountain and covers a distance of 2.3km. The hiker started at an elevation of 400m and ended at an elevation of 980m. What is the gradient of the mountain?
Matterhorn, Switzerland
a) Mountains – the greatest relief, and steepest slopes.
-Metamorphic rock
b) Plateau – flat elevated land with deep valleys cut by streams.
- Horizontal sedimentary rock
c) Plains – least topographic relief.
Great Plains, USA
Matterhorn, Switzerland
Colorado Plateau
II. Climate and Landscapes
1. The amount and distribution of precipitation influence landscape characteristics.
Very Wet
Wet
Moderate
Dry
A) Wet climate mountains have rounded peaks and show gentle slopes.
B) Arid (dry) climate mountains have pointed peaks and steeper slopes.
How do the mountains on the East Coast
compare to the mountains on the West Coast of the
United States?
Appalachian Mountains, East Coast United States
Rocky Mountains, West Coast United States
2. The composition of the rock influences landscapes.
A) Strong (durable or competent) rock does not erode easily and forms steeper slopes
- escarpments (cliffs), are created by durable rocks
B) Softer rock erodes faster forming gentle slopes
Banks of Yellow River, China
III. Drainage Patterns
- mimic the landscape they form in.- follows the elevation and contour of the
land.- Starts as small streams and tributaries
and ends in rivers.
= Plains
= Mountains
= Plateau
Closure:
1)Take the worksheet from the back table.
2) You and your partner should work on the FRONT SIDE of the worksheet together.
