Study Notes
Landforms and Their Forces
- Landforms include mountains, plateaus, deserts, and coastal plains, shaped by natural forces over time.
- Endogenic forces originate from within the Earth, causing folding, faulting, earthquakes, and volcanic activity.
- Exogenic forces act on Earth’s surface via wind, water, and glaciers, leading to weathering, erosion, transportation, and deposition.
Mountains
-
Mountains rise at least 1,000 feet above surrounding landscapes, featuring steep sides and peaks.
-
Fold Mountains are formed by the compression of the Earth's crust during tectonic plate collisions.
- Young Fold Mountains (10-25 million years old) include the Himalayas and Rockies, often exhibiting geological activity.
- Old Fold Mountains (over 200 million years old) like the Appalachians show erosion features such as rounded peaks.
-
Block Mountains form when one faulted side shifts upwards, creating uplifted regions, known as horsts, e.g., the Sierra Nevada in the USA.
-
Volcanic Mountains arise from magma ejected during eruptions, forming conical shapes over time, such as Mt. Kilimanjaro and Mt. Fuji.
Importance of Mountains
- Serve as natural resources reserves, providing minerals, timber, and medicinal herbs.
- Perennial rivers from snowy mountains contribute to irrigation and lower valley fertility.
- Act as political boundaries, illustrated by the Himalayas separating India and China.
- Influence local climates by altering weather patterns and supporting tourism, with destinations like Shimla and Nainital attracting visitors.
Valleys
- Valleys are common landforms shaped by the erosion of flowing water or ice.
- River Valleys are V-shaped and formed by water action, with the Grand Canyon as an example.
- Glacial Valleys are U-shaped, created by glaciers scraping the earth.
- Rift Valleys emerge from tectonic plate movements; notable examples include the Great Rift Valley in East Africa.
Plateaus
- Plateaus are elevated, flat areas characterized by steep sides, covering about 18% of Earth's surface.
- Formation involves volcanic activity or erosion over time, producing various types:
- Intermontane Plateaus, like Tibet, are located among mountains.
- Piedmont Plateaus, like the Malwa Plateau, lie at mountain bases.
- Continental Plateaus, such as Maharashtra Plateau, form away from mountains.
Significance of Plateaus
- Rich in minerals, facilitating easier extraction compared to mountains.
- Hydro-power generation potential from waterfalls at plateau edges.
- Support agriculture due to fertile soils, particularly in lava plateaus.
Plains
- Plains are flat, low-lying areas formed mainly by sediment deposition from rivers and other agents.
- Classified as:
- Structural Plains with undisturbed rocks.
- Depositional Plains formed by sediment deposition (e.g., alluvial plains).
- Erosional Plains created by the wearing down of elevated land.
Indo-Gangetic Plains
- Large floodplains of the Indus and Ganga-Brahmaputra rivers, crucial for agriculture and settlements, densely populated due to fertile soil.
Impact of Landforms on Human Life
-
Life in Mountains:
- Sparse population due to tough living conditions and limited agricultural opportunities.
- Houses are typically made of wood with slanting roofs; traditional clothing is warm and thick.
- Economy focus on agriculture, handicrafts, and tourism.
-
Life in Plains:
- High population density facilitated by flat terrain for construction and transport.
- Houses are sturdier, featuring a variety of materials based on climate.
- Agriculture thrives due to fertile soil leading to diverse crop production and industrial opportunities.
-
Transportation: Mountains have limited transport networks, while plains support robust infrastructure due to their level terrain.
