Agro-Chemicals & Their Effects

In the wake of green revolution, use of inorganic fertilisers and pesticides has increased manifold for enhancing crop production. Pesticides, herbicides, fungicides, etc., are being increasingly used. These incidentally, are also toxic to non-target organisms,that are important components of the soil ecosystem. Do you think these can be biomagnified in the terrestrial ecosystems? We know what the addition of increasing amounts of chemical fertilisers can do to aquatic ecosystems vis-à-vis eutrophication. The current problems in agriculture are, therefore, extremely grave.

Global distribution of Fold Mountains and the Earthquakes and Volcanoes.

Fold mountains are formed from sedimentary rocks that accumulate along the margins of continents, when two tectonic plates move together. When the plates and the continents riding on them collide, the accumulation layers of rock may crumple and fold, particularly if there is a mechanically weak layer such as salt. These accumulated layer or sediments are then pushed together by volcanic islands to form folds, which eventually form fold mountains.  Mostly, in the interaction between oceanic plate and continental plate, oceanic plate gets subducted beneath the margins of continental plates, giving rise to mighty mountains. This activity can occur only on the margins of continents, as a result of which fold mountains are observed along the margins of continents.  Fold mountains are distributed throughout the world in the eastern margins of Mediterranean to Western Pacific, West Coast of South America and Appalachians Mountains of North America. The earth quakes in these regions o...

The Mughal School Of Painting (1560-1800 A.D.), Mughal Empire Art & Culture

Image
The origin of the Mughal School of Painting is considered to be a landmark in the history of painting in India. With the establishment of the Mughal empire, the Mughal School of painting originated in the reign of Akbar in 1560 A.D. Emperor Akbar was keenly interested in the art of painting and architecture. While a boy he had taken lessons in drawing. In the beginning of his rule an ateliar of painting was established under the supervision of two Persian masters, Mir Sayyed Ali and Abdul Samad Khan, who were originally employed by his father Humayun. A large number of Indian artists from all over India were recruited to work under the Persian masters. The Mughal style evolved as a result of a happy synthesis of the indigenous Indian style of painting and the Safavid school of Persian painting. The Mughal style is marked by supple naturalism based on close observation of nature and fine and delicate drawing. It is of an high aesthetic merit. It is primarily aristocratic and secular. An...

the consequences of spreading of ‘Dead Zones’ on marine ecosystem

Image
Dead zones are low-oxygen, or hypoxic, areas in the world’s oceans and lakes. Because most organisms need oxygen to live, few organisms can survive in hypoxic conditions. That is way these areas are called dead zones. Dead zones in the coastal oceans have spread exponentially since the 1960s and have serious consequences for ecosystem functioning. One of the largest dead zones forms in the Gulf of Mexico every spring. Hypoxic zones can occur naturally but climate change, nutrients run-off from the land, and eutrophication are leading to algal bloom and causing further depletion of oxygen level in water. As a result dead zones are spreading at much faster pace.  Consequences of spreading of Dead Zones on Marine Ecosystem  •The reduced dissolved oxygen in ocean water results in loss of marine life thus the habitats which were once teeming with life are transformed into biological deserts.  •Elevated nutrient levels and algal blooms can also cause problems in drinking water ...
