Landscapes

1. Landscapes

2. Landscape Development • Landscapes: • A region on Earth’s surface in which various landforms are related by a common origin.

3. Factors That Impact Landscape Development • Climate • Local Bedrock • Geologic Structures • Human Activities

4. Types of Landscape Regions • Mountains: • Has the greatest relief between the highest peak and the deepest valley. • Relief: (change in elevation from the highest point to the lowest point) • RELIEF: 10m - 0m = 10m 10m 0m

5. HOW ARE MOUNTAINS CREATED? • A daddy mtn and a mommy mtn fall in love and because they love each other so much……. • MR. O’D!!!!!!!!!!!!!!!!!!!!!!!!!!!! Hey Mama!!!!

6. HEHEHE • Tectonic forces push Earth up to create a mtn. • Convergent plate boundary

7. Plateau • A plateau landscape is often relatively flat or rolling uplands that streams have cut valleys into. • Rock structure: • “It’s sedimentary my dear Watson” • Smaller relief than mtns • Larger than plains • Examples of plateaus: • Colorado Plateaus near the Grand Canyon

9. Plains • Plains are generally flat and are at a lower elevation. • Rock Structure: flat layers of sedimentary rocks. • Midwest and Florida

10. Landscapes and Culture • Landscapes help shape the culture of an area. • Physical boundaries can help bring together communities for a common need or shut off a community.

11. Climate and Landscapes • Landscapes in moist environments are generally rounded. • (Chemical Weathering, Good Soil) • Those is arid environments show sharp angles and steeper slopes. • (Physical Weathering, Not Enriched Soil)

13. Drainage Patterns • Drainage Patterns: The way water runs off of a landscape. • Rule of thumb: • Streams will tend to follow zones of weaker rocks.

14. Four Types of Drainage Patterns • Dendritic: • Branching • Usually found on flat laying rock or uniform rock. • Ex. Appalachian Plateau near Oneonta

15. 2. Radial • Rolls off of a dome • Usually found by a circular volcano or dome mountain. • Ex. The rim of the Adirondacks

16. 3. Rectangular • Follows zone of weaker rocks in rectangular patterns. • Usually found in faulted, tilted or folded rock layers. • Ex. Finger Lakes and the Central Adirondacks.

17. 4. Annular • Circles, then down, circles, then down. • Usually found when you have a dome with upturned layers. • Ex. Esopus Creek near Phoenicia, NY.

18. New York and the Ice Ages • New York was covered with glaciers • Alpine glaciers: valley glaciers, these are the ones that make U shaped valleys and move due to their weight and the slope of the land they are on. • Continental glaciers: ice sheets that move solely on their own weight. • The Finger Lakes were created by advancing glaciers.

19. Erosion and Deposition by Glaciers • Erosion: takes away from the land • Ex. Finger Lakes • Deposition: adds to the land • Ex. Drumlin: tear shaped hills created in front of the advancing glacier. • Ex. Moraines: plies of unsorted soil and rocks left where the glacier stopped advancing. (Long Island shows this)

20. Drumlin

22. Terminal Moraine

25. Kettle Lakes • : when buried blocks of ice cause a depression in the ground and it fills with water.
