There are some misconceptions about the dynamics of the monsoon circulation in Indian subcontinent. Recent observations and theories derived from them have helped the meteorologists, geographers and environmentalists to see, in a new light, the processes involved and the consequent results. This programme is meant to help understand global planetary wind system.

What Is A Rock

Duration : 17:10     Year : 1988     Code No.239

We have seen it; touched it and perhaps ignored it. But the study of rocks offer us a mine of information as well as provide us with valuable clue to metal and mineral resources. Here we learn about some of the characteristics and about the origin and development of various categories of rocks.

Journey To The End Of The Earth

Duration : 23:18     Year : 1988     Code No.643

"Journey to the End of the Earth" is a programme on the World's last Great natural wilderness, The Antartica. As the programme would highlight, in spite of its isolation and extreme climate it has a special natural beauty. It has truly become a continent for science, and the object of this programme is to highlight and garner fuller understanding of the continent itself.

Mapping the Ocean Floor

Duration : 18:15     Year : 1989     Code No. 249

Oceans are not only reservoirs of water; they have a lot of economic significance to a country. Sir Anthony Laughton was Director of the Institute of Oceanographic Sciences in the U.K. This programme is an interaction with him. The whole concept of the way that the geology
of the earth works has emerged from a study of the marine geology. The coastal states now have a tremendously extensive area added to their own land areas in the form of an Extensive Economic Zone, extending 200 miles out from the coastline. How do they study the ocean floors now?

Study Of Metamorphic Rocks - A Modern Approach

Duration : 20:47     Year : 1994     Code No.2306

The earth is the giant source of primeval heat. Parent rocks, under the influence of pressure and temperature, are metamorphosed. The three major types of metamorphism are burien, regional and contact. This programme tells us how to identify minerals and thus, rocks, with the naked eye, under the microscope or by chemical or geochemical tests and goes on to present larger perspectives of metamorphism in terms of plate tectonics.

Hidden In Rocks

Duration : 23:33     Year : 1994     Code No. 3308

Rocks are often considered dead inanimate objects. In the hands of a structural geologist, however, they become storytellers. They can reveal to us valuable information about conditions at the time of the crystal formation. Study of rock structure is also essential for locating the mineral sites of a region.
