1. Landscape Classification
There are three main types of landscape regions:
Plains
Plateaus
Mountains
All three types can be found in NY State.
All landforms are the result of the interaction between uplifting and leveling forces. These include:
Tectonic forces
Weathering
Erosion
Deposition

4. Features of Plains
Plains are characterized by low elevation and low relief (very little change in elevation).
Usually formed by the deposition of sediments at or below sea level.

5. Features of Plateaus
Plateaus have horizontal bedrock structure at moderate to high elevation.
The rock layers were originally deposited at or below sea level and have since been uplifted.
I took top picture at Grand Canyon; I took the bottom picture in Utah

6. Features of Mountains
Mountains typically show highly deformed bedrock structure, high elevation and high relief.
The folding, tilting and metamorphism of mountainous bedrock is a result of the processes that formed the mountains.

7. Landscapes in Arid Climates
Arid (dry) landscapes:
steep slopes
sharp and angular landscape features
little vegetation to hold sediments in place
I took picture at Grand Canyon

8. Landscapes in Humid Climates
Humid landscapes
smoother and more rounded landscape features
sediments are held in place by vegetation.
I took picture at Shenandoah National Park

9. Highland (mountain), plateau, or lowland (plain)?
I took left picture over Utah; I took middle picture at Grand Canyon; I took right picture in Switzerland
Plateau!

10. Drainage Patterns
Variations in bedrock composition influence the drainage pattern of a landscape. This is because some rocks are more resistant to weathering and erosion than others.
We can categorize stream drainage patterns into 4 main types...
Diagram from:

11. Dendritic Drainage Pattern
Similar to the branches of a tree.
Form in regions where there is a relatively uniform resistance of bedrock to weathering.

12. Radial Drainage
Drainage from a central point of higher elevation, such as the top of a volcano or mountain.
The pattern extends outward from the highest elevation.
The Adirondack Mountains display this type of drainage.

13. Trellised Drainage Tributaries are at nearly 90° angles to the stream.
I took picture flying to Colorado

14. Annular Drainage
Appears ring-shaped as they form near circular bedrock structures that have been eroded.
