Evaporation is the phenomenon by which water changes its state from liquid to gas. Although water starts to boil from 212 degrees Fahrenheit, it begins evaporation at 32 degrees Fahrenheit. The procedure through which the water starts changing its form from liquid to gaseous state is quite slow. Evaporation is, therefore, the natural phenomenon by…
Nature is the laboratory of all the scientific incidents that surround our life and living. The diverse processes of nature also determine how the environment in which we live will be. So it becomes absolutely necessary for us, and especially for our younger generation to learn more about these vital natural phenomena that affect our…
Condensation is the process by which water in the gaseous state reverts to the liquid state on meeting a cooler surface or a region with lower temperature conditions. This process occurs alongside evaporation. Whereas evaporation has to do with the escape of molecules of liquid water from the liquid to the vapor or gaseous state…
Generally, evaporation is the process by which liquid matter under conditions of high temperature, escape as gas molecules. Water evaporation, similarly, is a process by which water molecules under high conditions of temperature change phase from liquid to gaseous form (where it escapes as gaseous water molecules or droplets). Water evaporation occurs because, at high…
Infiltration refers to the process where precipitation or water infuses into subsurface soils, is absorbed by the soil and travels deeper through pore spaces and cracks into rocks. The bulk of water collected from melted snow and rain end up infiltrated. Where exactly does it reach in the ground? Water is often soaked up by the…
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 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…
The soil formation process depends upon the presence of new soil material which is either acquired by denudation or deposition. Denudation is the abrasion of present rock material by the action of ice, water or wind. Deposition is the accumulation of new materials that have been eroded from another place such as river gravels or…
Precipitation is the falling of water from the sky in different forms. They all form from the clouds which are raised about 8 to 16 kilometers (4 to 11 miles) above the ground in the earth’s troposphere. Precipitation takes place whenever any or all forms of water particles fall from these high levels of the…
Up to the present time, when it comes to discussions about the earth’s surface cover, most of it is covered by water. About 70% of the entire earth’s surface is overlaid with water, most of which are the oceans. Out of the total water surface on earth, more than 96% is the ocean’s salty water….
Clouds are composed of ice crystals or water drops suspended and drifting in the sky at considerably high altitudes. The water droplets are very minute with a diameter of roughly a hundredth of a millimeter. This means that each cubic meter of air is made up of about 100 million droplets. The composition of ice…
Hurricane is a severe tropical cyclone – rapid inward circulation of air masses about a low pressure centre, usually with heavy rains and winds moving at 73 to 136 knots (miles per hour) forming over the Atlantic Ocean or Eastern Pacific Ocean. Hurricanes are witnessed as massive storms during powerful rains with strong winds, lightning, and…
The water cycle explains the continuous movement of water on, above, and below the surface of the earth. It is also referred to as the Hydrological Cycle. The cycle describes the properties of water that make it undergo the various movements on the planet. The water cycle has nine main physical processes that create a…
