Origins of Landforms
Overview of Materials for Landform Activities
Landform Activity
Demos that Accompany this PPT
Origins of Landforms
TEKS 8.14 (A)
predict land features resulting from gradual changes such as mountain building, beach erosion, land subsidence, and continental drift;
Learning Objectives
Identify landforms
Explain the role of geological structures,
igneous activity, water, wind, and glaciers in
the origin of landforms
Explain how weathering, erosion,
subsidence, and uplifting create
landforms
Major Types of Landforms
Mountains (volcano, fault block mountains)
Plains (coastal and interior plains)
Plateau (broad flat areas of land)
Volcano and Fault Block Mountains
Coastal and Interior Plains
Plateau
Plateau in Albuquerque NM
Landforms Origins
Geological structures
Glaciers
Igneous activity
Running water
Ground water
Wind
Waves and currents
Geological Structures
This is how mountains, plains, plateaus, canyons, and mesas are formed
Glaciers
This is how cirques, horns, tarns, finger lakes, U-shaped valleys, and hanging valleys are formed.
Igneous Activity
This is how cinder, shield, and composite cone volcanoes, and calderas, are formed.
Arenal Volcano in Costa Rica
Running Water
This is how alluvial fans, oxbow lakes, and meandering streams, are formed.
Ground Water
This is how sinkholes and caves are formed.
Sinkhole at Chichen Itza, Mexico
Wind
This is how dunes are formed.
Waves and Currents
This is how headlands, sea arches, sea cliffs and beaches.
Demonstrate Formation of Syncline, Anticline, and Faults
ENGAGE
