Study Notes
Mountain Formation
-
Types of mountain formation:
- Volcanic: formed from volcanic activity
- Fold: formed when tectonic plates collide and push up the Earth's surface
- Block: formed when large sections of the Earth's crust break and move upwards
- Dome: formed when magma rises and pushes up the Earth's surface
-
Mountain-building processes:
- Orogenesis: the process of mountain formation through tectonic plate collision
- Uplift: the process of the Earth's surface rising due to geological forces
Plate Tectonics
-
Theory of plate tectonics:
- The Earth's lithosphere is broken into large plates that move relative to each other
- These plates interact at their boundaries, causing geological activity
-
Types of plate boundaries:
- Divergent: where plates move apart and new crust is formed
- Convergent: where plates move towards each other and collide
- Transform: where plates slide past each other horizontally
-
Plate tectonics and mountain formation:
- Plate convergence can lead to mountain formation through folding and uplift
Volcanic Landforms
-
Types of volcanic landforms:
- Shield volcanoes: gently sloping volcanoes with a broad base
- Composite volcanoes: tall, conical volcanoes with a steep slope
- Calderas: large depressions formed by volcanic collapse
- Volcanic fields: areas of numerous small volcanoes
-
Volcanic features:
- Lava flows: streams of molten rock that flow from a volcano
- Volcanic ash: small particles of rock ejected into the air
- Volcanic cones: cones formed by accumulated volcanic ash and rock
Desert Landforms
-
Types of desert landforms:
- Dunes: ridges of sand formed by wind
- Ergs: large areas of sand dunes
- Oases: isolated areas of vegetation in the desert
- Playas: dry lake beds
-
Desert formation processes:
- Deflation: the removal of fine particles by wind, leaving behind coarser grains
- Erosion: the removal of rock and soil by wind and water
Coastal Features
-
Types of coastal features:
- Beaches: areas of sand or pebbles along the coastline
- Cliffs: steep slopes or vertical faces along the coastline
- Headlands: areas of land that jut out into the sea
- Bays: areas of water partially enclosed by land
-
Coastal formation processes:
- Wave erosion: the wearing away of the coastline by waves
- Deposition: the accumulation of sediment along the coastline
- Longshore drift: the movement of sediment along the coastline by waves and currents
