Shale gas refers to natural gas that is trapped within shale formations. Shales are fine-grained sedimentary rocks that can be rich sources of petroleum and natural gas. Over the past decade, the combination of horizontal drilling and hydraulic fracturing has allowed access to large volumes of shale gas that were previously uneconomical to produce.  Typical components of oil shale gas are usually methane, … Read more

The reasons for the diversity are as follows:   Over geological times the tropics have had more stable climate than the temperatezones. In tropics, therefore, local species continued to live there itself, whereas intemperate they tend to disperse to other areas. Tropical communities are older than temperate one’s and therefore there has beenmore time for … Read more

Inland water transport contribute just 1% of the total freight and as the data suggest it is underutilised as in other countries the proportion of freight is relatively high. There are challenges in the development of Inland waterways in India and they are as … Read more

The definition of function varies across the disciplines. In political science it refers to duties, in mathematics it means the relationship between two variables and in geography it is synonymous to occupation. Geographers have classified towns on the basis of their site, situation, size, rank, location and relative elevation. Functional classification of towns attempts to categorize towns … Read more

The continental shelf is the extended margin of each continent occupied by relatively shallow seas and gulfs. It is the shallowest part of the ocean showing an average gradient of 1° or even less.  The shelf typically ends at a very steep slope, called the shelf break. Geographical significance: The continental shelves are covered with … Read more

Tides are great bulges of water caused by the gravity of the moon and the sun. Attracted by gravity, these bulges move around the earth’s ocean, causing water level to rise and fall. There are two main tides that are higher or lower than average. They occur twice monthly and are called neap and spring … Read more

Most important sorts of ocean deposits are: Terrigenous Deposits Body of water Deposits. There are loose sediments, deposited on the ocean bottom. These are ocean deposits. They vary from location to location. The study of ocean deposits is vital in beneath standing the rocks exposed on the earth’s surface that were once set under ocean. … Read more

: Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”   Upwelling occurs in the open ocean and along coastlines. The reverse process, called “downwelling,” also occurs when wind causes surface water to … Read more

High-altitude adaptation in humans is an instance of evolutionary modification in certain human populations, including those of Tibet in Asia, the Andes of the Americas, and Ethiopia in Africa, who have acquired the ability to survive at extremely high altitudes. People living in high altitude can  inhale more air with each breath and breathe more … Read more
