Migration of Birds
Migration of birds is a natural practice in the life cycle of birds. Different species of birds fly hundreds and thousands of kilometers to find food and a safe sheltered place to nest and breed for their survival. Birds require specific and richest environmental resources for reproduction and to raise their young. When the conditions at the breeding sites become unfavorable, migrating birds adapt to the seasonal changes and fly to the regions where the climatic conditions are better. Read More

The major natural causes of wildfire are volcanic eruption, lightning, spontaneous combustion and sparks from rockfalls. Wildfires can also occur due to the accumulation of grass, leaves, and twigs in a pile which creates heat that ignites the surrounding area.

Tsunamis are caused by undersea earthquakes that lead to the displacement of a large volume of a body of water. These are a series of giant ocean waves that can move thousands of miles across the sea with tremendous force and energy. They have massive destructive power. They can be generated by volcanic eruptions, earthquakes, underwater landslides, large meteorite impacts, etc. They move at speeds between 500 and 800kph and can go up to 10 to 15 m in height. Tsunamis can have wavelengths ranging from 10 to 500 km and wave periods of up to an hour. Read More
