The Yamuna Biodiversity Park | Example of Wasteland Restoration

Backdrop of Wasteland Restoration Wastelands are degraded lands where the soil might have low productive capacity. Wastelands include areas that are affected by erosion, shifting cultivation, high salinity or alkalinity, riverine lands, or lands that are affected by water logging, or moisture deficiency. Such areas can be ecologically unstable, with displacement of top soil, and are thus also unsuitable for agricultural activity. However, such lands can be restored. There are several examples...

Plate tectonics | Quick recycling of Earth’s crust in less than 500 million years

Plate tectonics and the mantle You may feel that the grounds you play football on every evening is unchanging as ever. However, nothing can be further from the truth. The earth's crust too undergoes a cycle of birth and death that have changed the way our planet looks over millions of years. In 2011, scientists found evidence that this cycle was quicker than thought: 500 million years instead of 2 billion. The tectonic plates that constitute the crust are pushing, pulling or brushing past one another,...

Understanding the Hadley Cell | The Single Cell Circulation

Heat is transferred from the equatorial to the polar regions by a system of wind circulation that is independent of the longitudes, called axisymmetric circulation (symmetrical to the Earth’s axis), and is commonly referred to as the Hadley Cell of single cell circulation. In the Hadley Cell, the warm air at the equatorial regions rises and moves towards the polar regions and then sinks at the higher latitudes due to the colder temperatures of these regions. This air then begins moving back...
