The Southern Ocean is also known as the Antarctic Ocean located in the Southern hemisphere that surrounds the Antarctica. It is ranked as the fourth- largest of the five principal oceans in the world constituting 15 percent of the earth’s waters. The Southern Ocean is the newest named ocean recognized by the United States Board …
The Indian Ocean is the third largest oceanic divisions in the world next to the Pacific Ocean and the Atlantic Ocean. It is but larger than Antarctic Ocean (Southern Ocean) and Arctic ocean covering 20 percent (one-fifth) of the world waters. It is scattered with thousands of tropical Islands such as the Seychelles and the …
In geology, a fault is a discontinuity that is formed by fracture in the surface rocks of the Earth (up to 200 km deep) when tectonic forces exceed the resistance of the rocks. In other words, a fault is a crack in the Earth’s crust. The rupture zone has a generally well defined surface called the fault …
Fold occurs when rock deforms in such a way that it bends instead of breaking. The rocks, like any other material, deform to the action of external efforts. We do not grasp this deformation, but we know when a rock is deformed. Folds come from pressure on the rocks that occur over very long periods …
Overdependence on fossils fuels has led to a hail of environmental problems the universe faces today such as climate change, oil spills, air pollution, and acid rains. Burning of fossils fuels to generate electricity releases dangerous greenhouse gasses like carbon dioxide, nitrous oxide, water vapor, methane, and fluorinated gasses that cause the greenhouse effect. For …
After the Pacific Ocean, the Atlantic Ocean is the largest ocean on Earth. The Atlantic is divided by the Equator in two rather artificial sections: the North Atlantic and the South Atlantic. Its name derives from Atlantikos (Atlas – the sea beyond the Atlas Mountains), one of the Titans of Greek mythology. Size and Boundaries …
Pacific Ocean is the largest ocean in the world in terms of weight and depth. It covers more than one third of the surface of the Earth and contains more than half of its volume of water. It is usually done, artificially, a division from the line of Equator: the North Pacific and the South Pacific. …
The shallowest and smallest out of the five oceans, the Arctic, can be found in the northern hemisphere. Its name comes from the word ‘’Arktos’’ which means bear in Greek. Despite the cold, the territory in these waters has been fairly populated for around 20,000 years ago by Eskimos that of course, are physically and …
The Atlantic Ocean is a huge mass of water covering about 16.7-20 percent of the Earth and covers a total area of approximately 85,133,000 square kilometers. To get a clear idea about its size, it is important to note that it is slightly greater than half of the Pacific Ocean. This ocean has an average …
The Pacific is the largest ocean on Earth, discovered by Ferdinand Magellan. This huge mass of water is stretching from the Arctic to the Southern Ocean from the Bering Sea in Alaska to the Ross Sea in Antarctica. It binds with the Atlantic Ocean through the Bering Strait in the north and south across the …
Succession is a series of progressive changes in the composition of an ecological community over time. Succession is directional. Different stages in a particular habitat succession can usually be accurately predicted. Ecological successions are the noticeable changes that occur in an ecological setup over time. These changes are often predictable and take place in an …
Mass wasting can be defined as a geomorphic process. A geomorphic process is a natural course of weathering, erosion and deposition that causes alteration of the surface materials and landforms of the earth. Mass wasting is also known as slope movement or mass movement. It can be described as the potency by which certain landforms like …
‘Coriolis effect’ or Coriolis force can be defined simply as deflection of wind. Winds and ocean currents are in constant motion. This movement does not follow a straight line but bends and curves. This is the Coriolis effect which is noticeable in the curvature of global winds, and all that is free flowing across the …
A Food chain can be defined as the feeding relationship between the different organisms that make up our ecosystem. An ecosystem is a commune of living organisms. The ecosystem also includes the non-living components like, earth, water, fire, air and ether. The living and non-living together form the environment. Within the environment, the living or …
The physical world is composed of living and non-living things. They are generally referred to as the biotic and the abiotic. The abiotic is the physical objects like rivers, mountains, volcanoes and water-bodies. The biotic is the world of flora and fauna. Flora The word “flora” is used to designate plant life. The word “flora” …
