Bioaerosols are a subcategory of particles released from terrestrial and marine ecosystems into the atmosphere. They consist of both living and non-living components, such as fungi, pollen, bacteria and viruses. Common sources of bioaerosols include soil, water, and sewage.

Bioaerosols are thus highly relevant for the spread of organisms, allowing genetic exchange between habitats and geographic shifts of biomes. Moreover, bioaerosols can serve as nuclei for cloud droplets, ice crystals, and precipitation, thus influencing the hydrological cycle and climate.

Female energy was the important philosophy behind Tantra. Women were considered equal to men in the practise of Tantric Rituals.

Tantra focussed on rituals and hymns as they were considered to have an element of magic and mystery in them.

Import substitution was the principle behind the second five year plan. It was decided that India did not have adequate Forex Reserves to import basic and capital machinery from foreign countries. Hence there was a focus in the second five year plan on increasing the investments into Capital Industries.

The targeted growth in GDP at the end of the plan period was 4.5%. However the achieved growth at the end of the plan period was only 4.2%.

Desert locusts (Schistocerca gregaria) are a short-horned grasshopper species. The FAO deems them the most dangerous migratory pests in the world due to their ability to change behaviour and form swarms that consume everything in their path.

Climate change and its impact on the monsoon is thought to cause range expansion in locust swarms. In terms of the environmental implications, locusts impact native grazing species that rely upon grasslands and croplands for survival. Swarms consume everything in their path, leaving behind ruined cropland and barren pastures. While they are not known to impact forests or natural tree cover, their voracious consumption of most species of crop creates food scarcity for native fauna and other insects. In Kenya, for example, locust plagues threaten the habitat of the Grevy’s zebra, a threatened endemic species

Andesitic, or acidic lava highly viscous with a high melting point. They are light-coloured, of low density, and have a high percentage of silica. They flow slowly and seldom travel far before solidifying. Basic or Basaltic or Shield lava are the hottest lavas, about 1,000 °C and are highly fluid. They are dark coloured basalt, rich in iron and magnesium but poor in silica.
