Aim: How are landscapes defined? Do Now: Try to define the following landscapes in by giving descriptions and facts that characterize each landscape. 1) Plains 2) Plateau 3) Mountain

I. Landscapes (Regions): areas on Earth that has been affected by uplifting, weathering and erosion. specific bedrock specific elevation Canadian Rocky Mountain Park, British Columbia Great Plains, Nebraska

Erosion, Uplift and Deposition are EQUAL What would erosion do to a landscape? - Erosion lowers the land (decreases elevation) What would uplift or deposition do to a landscape? - Uplift and Deposition builds the land up (increases elevation. What would cause there to be no change in a landscape? Erosion, Uplift and Deposition are EQUAL This is called Dynamic Equilibrium

b) Plateau – flat elevated land a) Mountains – the greatest relief (elevation) and steepest slopes, mostly metamorphic rock b) Plateau – flat elevated land with deep valleys cut by streams, mostly horizontal sedimentary rock layers c) Plains – least topographic relief, mostly sedimentary rock. Matterhorn, Switzerland Colorado Plateau Great Plains, USA

REMEMBER 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 252.2m/km distance Gradient = Change in field value

How is precipitation different across the United States? II. Shaping Landscapes A. Precipitation. Very Wet Wet Moderate Dry How is precipitation different across the United States?

Wet climate create landscapes with rounded peaks and gentle slopes. - Arid (dry) climates create landscapes with 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

B. Rock Composition (what it is made of) - Strong (durable or competent) rock does not erode easily and forms steeper slopes - escarpments (cliffs), are created by durable rocks

III. Drainage Patterns mimic the landscape they form in. follows the topography (shape) of the land.

= Plains = Mountains

= Plateau = Mountains and Valleys

Annular = Igneous dome that pushed up surrounding layers of rock.
