New View of Lunar Crater

Posted on September 2, 2010 by Rashid Faridi

NASA has released an interesting  geolologic map of moon.

NASA’s got something new for the geo-geeks in the house: a bedrock geologic map of Schrodinger Basin, a giant crater near the moon’s south pole that formed from a collision with a space rock 21-25 miles in diameter.

The green areas are huge swaths of melted material, while the black lines running through them are fractures formed as the whole hot mess cooled. Later on, smaller objects slammed into the crater and created their own mini-areas of devastation, highlighted here in yellow.

One of the things that makes Schrodinger interesting are the red and beige patches: evidence of some of the most recent volcanic activity near the moon’s south pole. The beige are lava flows, while the red — the youngest rocks pictured here — are deposits from explosive eruptions.

Putting India on World Petroleum Map :India is now top exporter of petro products in Asia

Posted on September 1, 2010 by Rashid Faridi

According to the data compiled by oil and metal information provider Platts, India’s gross exports currently average 1 million barrels a day, inching past South Korea which exports 0.9 million barrels a day.

With the commissioning of a new refinery by Reliance Industries at Jamnagar and Essar Oil increasing refinery output at Vadinar, India overtook South Korea by mid-2009 and has since then consistently maintained the lead position.

Carnivore Species Shrank During Global Warming Event

Posted on August 31, 2010 by Rashid Faridi

A new University of Florida study indicates extinct carnivorous mammals shrank in size during a global warming event that occurred 55 million years ago.The study, scheduled to appear in the December print edition of the Journal of Mammalian Evolution and now available online, describes a new species that evolved to half the size of its ancestors during this period of global warming.

Drainage Basin

Posted on August 30, 2010 by Rashid Faridi

The land based part of the hydrological cycle is called the Drainage Basin System. A drainage basin is the name given to the area of land which is drained by a river. When water reaches the surface there are a number of routes which it may take in its journey to reach the river. These are shown in the diagram .

Drainage Basins have a number of distinct features . The edge of a drainage basin is characterised by the highest points of land around the river, this is known as the watershed. The point at which a river starts is called its source. As the river continues to flow down stream it may be joined by smaller rivers called tributaries. The point at which these smaller rivers join the main river is known as a confluence. As the river continues its journey, eventually reaches the sea – the point where the river flows into the sea is known as the river mouth.
