sea ice reduction

Globally sea levels have risen 4-8 inches over the last century. The high temperatures have already started melting polar ice caps sea icebergs and glaciers. This has released enormous amount of water. Warmer temperatures also heat water and make it expand; thus ocean..

Salt Water: It constitutes the oceans and the seas. Nature has comparatively more salt water than fresh water Fresh Water: Fresh water is an unlimited natural resource. Its quality is often degraded but there is no reduction in quanti..

About 70-73% of earth is covered by water. Water is available in the form of oceans, seas, rivers, lakes, ponds, pools, polar ice caps and water vapour and this forms the hydrosphere. The main component of hydrosphere is water. Water exists in all the three forms i.e., solid (sn..

Global Warming - The addition of certain pollutants like the carbon dioxide gases increases the temperature of the earth. These gases remain close to the surface of earth, forming an insulating layer. The surface becomes hot due to the solar radiations. This radiation is normally reflected back int..

>o C. Two examples illustrate this. Firstly, when water is heated in a pressure cooker, more and more steam is formed and it is not able to escape out. The pressure gradually increases and as a result, the boiling point starts rising much above 100 o C (Fig.6.3..

The surface becomes hot due to the solar radiations. This radiation is normally reflected back into the space. How..

. Thus in the tissue fluid, the respiratory gases are present in solution. As a person climbs up a mountain, the atmospheric pressure falls along with which, the partial pressures of the gases also fall. This reduces the partial pressure of oxygen in the lungs. Reduction of P O 2 in lungs..

In the Earth's biosphere, water is essential to all forms of life. Interestingly, it is also the biospheres most abundant compound and a unique substance from the chemical point of view. About 75% of the Earth's surface consists of water. Water is present as either (a) Solid - ice, snow e..
