Study Notes
Physical Geography Exam 3 Summary
-
Geomorphology: The study of Earth's physical features and their geological structures. Topography studies Earth's surface features. Relief refers to elevation differences. Low relief is relatively flat, high relief has significant elevation changes. Relief is a key concept in evaluating topographic features.
-
Igneous Processes: Involve the melting, movement, and cooling of molten rock (magma). Syncline is a rock fold with younger layers at the center. Fault is a fracture in Earth's crust with movement. Earthquakes measure magnitude on a scale. Different igneous processes result in varied landforms.
-
Weathering: The breakdown of rocks and minerals into smaller pieces. Mechanical weathering (e.g., unloading, freeze-thaw) physically alters rocks. Chemical weathering alters rocks' chemical composition. Erosion, transportation, and deposition are processes shaping Earth's surface through these changes and moving debris to new locations. Weathering rates are affected by climate, rock type, and presence of water. Types of weathering: mechanical (e.g., unloading, freeze-thaw) and chemical.
-
Fluvial Processes (Ch 13): Rivers/streams shape landscapes by carrying rocks and soil. Relationship between infiltration and surface runoff is significant. Factors influencing infiltration include soil moisture content, good vegetation cover, gentle slopes. Factors affecting surface runoff include land contours, steep slopes, soil compaction, and poor vegetation cover. Aquifers store and provide water, holding it in porous rocks and sediment. River processes influence landscape evolution.
-
Glacial Processes (Ch 14): Fluvial Geomorphology studies how rivers shape landscapes. Erosion is the wearing away of soil, sediment, or other material. Depositional features result from sediment deposition from water, wind, or ice. Examples include alluvial fans (sediment deposits at mountain bases) and oxbow lakes (crescent-shaped lakes formed from meandering rivers). Depositional landforms are shaped by sediment.
-
Glaciers (Ch 16): Glaciers flow through two mechanisms: Internal deformation and Basal sliding. Alpine glaciers (mountain glaciers) and Ice sheets (continental glaciers). Ablation is where ice is lost, and accumulation is where snow builds up. Crevasses are deep cracks in glaciers. Moraines are ridges of rock and sediment deposited by glaciers. Glacial processes significantly impact topography. Ice movement and deposition modify the landscape. Ablation exceeds accumulation, ice retreats. Accumulation exceeds ablation, ice advances.
