CONTINENTS


Definition and Distribution

Continents are large continuous masses of land, typically divided by oceans and seas. There are seven continents on Earth: Africa, Antarctica, Asia, Europe, North America, Australia (Oceania), and South America. Each continent has its own distinct geographic and cultural characteristics. Geological formation of continents; continents were formed through tectonic plate movements and volcanic activity over millions of years. Their current arrangement is a result of the shifting and colliding of Earth's crustal plates.




Climate Variability

Each continent experiences a range of climates, from the icy expanses of Antarctica to the tropical rainforests of South America. This diversity affects local weather patterns and ecosystems. Continents host unique flora and fauna, shaped by their varied climates and geographies. For example, Australia is home to marsupials like kangaroos, while Africa has iconic megafauna such as elephants and lions.



Human Settlement

The distribution of human populations across continents is influenced by geographic features and climate. Urbanization, agriculture, and industry are concentrated in certain areas based on resource availability and climate suitability.

Topic 10: Earthquakes

EARTHQUAKES Definition and Causes Earthquakes are the shaking of the Earth’s surface caused by the sudden release of energy from the Earth’s crust. This release of energy typically occurs along faults, which are fractures or zones of weakness in the Earth’s crust. The movement of tectonic plates—large pieces of the Earth’s crust—due to geological processes, such as subduction or rifting, is the primary cause of earthquakes. Measurement and Impact Earthquakes are measured using seismographs, which record the intensity and duration of ground shaking. The magnitude of an earthquake is often reported on the Richter scale or the Moment Magnitude Scale (Mw), which quantifies the energy released. Earthquakes can cause significant damage to infrastructure, leading to building collapses, landslides, and tsunamis, which can have devastating effects on communities and environments. Preparedness and Mitigation Understanding earthquake risks is crucial for effective preparedness and mitigation. Bui...
