Study Notes
Physical Features of the Earth
- Natural features on Earth's surface are classified as physical features, including mountains, hills, valleys, rivers, and lakes.
- Physical features are broadly categorized into landforms and water bodies.
Major Landforms
-
Definition: Variations in Earth's surface create diverse landforms, which can be flat or raised.
-
Mountains:
- Defined as lands rising over 900 meters above mean sea level; they feature steep slopes and peaks.
- Groups of mountains form mountain ranges, while multiple ranges together are known as mountain chains.
- Serve as barriers against winds, influencing precipitation.
- Examples in India: Himalayas, Aravalli Range, Karakoram Range; globally: Alps, Rocky Mountains, Andes.
-
Hills:
- Smaller high lands than mountains, characterized by gradual slopes and rounded peaks.
- Hill ranges consist of groups of hills, while valleys are low-lying lands between hills or mountains.
- Examples in India: Satpura Range, Nilgiri Hills, Lushai Hills; globally: Seven Hills of Rome, Nob Hill (USA), One Tree Hill (New Zealand).
-
Plateaus:
- High lands with steep slopes and flat tops, rising sharply from surrounding areas.
- Often rich in minerals and resources.
- Examples in India: Deccan Plateau, Chota Nagpur Plateau, Meghalaya Plateau; largest worldwide: Tibetan Plateau, other examples include Colorado Plateau (USA) and Bolivian Plateau (South America).
-
Plains:
- Flat, level landscapes known as lowlands, formed by sediment deposition from rivers.
- Fertile soil suited for agriculture and easier infrastructure development contributes to higher population density.
- Examples in India: Ganga Plain, Brahmaputra Plain, Sundarban delta; globally: Huang He Plain (China), Po Valley (Italy).
-
Deserts:
- Areas dominated by sand and rock, featuring scanty vegetation and low rainfall; experience extreme temperatures.
- Sand dunes are small hills of sand common in deserts.
- Examples include the Thar Desert (India), Great Sandy Desert (Australia), Arabian Desert (Asia), Atacama Desert (South America).
Water Bodies
-
Defined as accumulations of freshwater or saltwater on Earth's surface, classified into oceans, seas, lakes, and rivers.
-
Oceans:
- Enormous saltwater bodies surrounding continents; there are five primary oceans.
- Ocean water contains high levels of dissolved salts.
-
Seas:
- Larger than lakes but smaller than oceans, seas can be part of oceans or landlocked.
- Examples: Arabian Sea, Red Sea, Mediterranean Sea, Caribbean Sea; inland seas include Caspian Sea and Black Sea.
-
Lakes:
- Large water bodies encircled by land, which can be either freshwater or saltwater.
- Examples in India: Dal Lake, Chilika Lake, Vembanad Lake, Loktak Lake; globally: Lake Superior (USA), Lake Baikal (Siberia), Lake Victoria (Africa).
-
Rivers:
- Natural flowing water channels originating in mountains, hills, or plateaus, and ending in oceans, seas, or lakes.
- Key river terminology includes:
- Source: origin point of a river.
- Mouth: where a river meets larger bodies of water.
- Confluence: where two rivers meet.
- Tributary: a smaller river flowing into a larger one.
- Examples in India: Ganga, Brahmaputra, Godavari, Krishna, Kaveri; globally: Congo (Africa), Missouri (North America), Paraguay (South America), Rhine (Europe).
-
Mean Sea Level: Average level of ocean water globally, serving as the baseline for measuring land elevation and ocean depth.
