Main Body
Earthquakes are sudden amazing of the earth due to release of energy in the lithosphere.
The global distribution of earthquakes can be depicted as:
[Diagram showing earthquake distribution zones with labels (1) and (2)]
Fig 1: areas of earthquakes.
Global distribution
1Mid-Atlantic Belt → presence of mid-oceanic ridge
Earthquakes in Iceland: S vocafem in nature
3Pacific - wing of fire → meeting of Pacific plate with other smaller plate.
[Box:] Ocean - continental convergence at Pacific - Eurasian plateJapan
2Alpine - Himalayan belt → meeting of Eurasian plate with adjacent and divergent plate
[Box:] Earthquakes in Turkey, Italy
[Consequences associated]
1formation of volcanoes → volcano areas generally collide with earthquakes → ring of fire
2formation of layered plates → lead to medium earthquakes
[Box:] low density but confines earthquakes

Diagram
Map showing earthquake distribution areas with numbered zones (1) and (2), labeled as 'areas of earthquakes' with indication of Mid-Atlantic Belt
- Clear definition of earthquakes
- Includes diagram for visual representation
- Attempts to explain global distribution patterns
- References geological structures (mid-oceanic ridge)
- Connects plate boundaries to earthquake zones
- Provides specific geographic examples (Iceland, Japan, Turkey, Italy)
- Links earthquakes to volcano formation
- Mentions Ring of Fire concept
- Explains consequences of tectonic interaction
