Study Notes
Coastal Features
-
Beaches: Accumulations of sand, gravel, or pebbles along a shoreline
- Formed by wave action and longshore currents
- Can be erosional (steep) or depositional (gently sloping)
-
Cliffs: Steep slopes or vertical faces formed by erosion
- Can be formed by wave action, weathering, or tectonic activity
-
Headlands: Rocky or sandy points that jut out into the sea
- Formed by differential erosion or tectonic uplift
-
Bays: Curved or circular inlets of the sea
- Formed by tectonic subsidence, erosion, or sediment deposition
Desert Landforms
-
Dunes: Mounds or ridges of sand formed by wind deposition
- Can be stabilized by vegetation or migrate with wind patterns
-
Playas: Dry lake beds or flat areas formed by evaporation
- Can be temporary or permanent, depending on precipitation and evaporation rates
-
Oases: Isolated areas of vegetation in arid regions
- Formed around water sources, such as springs or wells
-
Canyons: Deep, narrow valleys formed by erosion
- Can be carved by water, wind, or tectonic activity
Mountain Formation
-
Folding: Process of mountain building through tectonic plate collision
- Forms mountain ranges, such as the Himalayas or Rocky Mountains
-
Volcanic Arcs: Chains of volcanoes formed by subduction zones
- Examples include the Andes or Japanese island arc
-
Block Faulting: Formation of mountains through vertical faulting
- Examples include the Sierra Nevada or Basin and Range Province
-
Uplift: Process of mountain building through tectonic uplift
- Can be caused by mantle plumes, hotspots, or tectonic convergence
Volcanic Landforms
-
Volcanoes: Landforms formed by magma eruption and accumulation
- Can be shield-shaped, stratovolcanoes, or cinder cones
-
Calderas: Large depressions formed by volcanic collapse
- Examples include Crater Lake or the Grand Canyon
-
Lava Flows: Channels of solidified lava formed by volcanic eruption
- Can be smooth (pahoehoe) or rough (aa) in texture
-
Volcanic Fields: Areas of numerous small volcanoes and lava flows
- Examples include the Hawaiian Islands or Iceland
