define salinity. |
| Answer» Salinity:A measure of the quantity of dissolved salts in sea water. The total amount of dissolved solids in sea water in parts per thousand by weight. The average ocean salinity is 35ppt and the average river water salinity is 0.5ppt or less. This means that in every kilogram (1000 grams) of seawater, 35 grams are salt. | |

Explain the differences between parallels and Meridians. |
| Answer» \tParallel / Latitude Meridian / Longitude Parallels are also known as latitudes\xa0Meridians are also known as longitudes\xa0Represented by the Greek letter phi (Φ)\xa0Represented by the Greek letter lambda (λ)\xa0The first parallel is the equator. It is latitude 0.\xa0Greenwich is the prime meridian (0°)\xa0Parallels don’t intersect.\xa0All meridians intersect at two places; the North Pole and the South Pole.\xa0Values range from 0 (the Equator) to 90 (the north and south poles)\xa0Values for longitude range from 0 (the Prime Meridian) to 180 degrees\xa0Letters N and S are used to denote the location\xa0Letters E or W are used to represent directionPositive values may be used in the Northern hemisphere and negative values in the Southern hemispherePositive values can be used east of the Prime Meridian and negative values in the west of the Prime Meridian\xa0Every parallel in the same hemisphere has a different length.Every meridian on Earth has the same length.\xa0Every parallel is a full circle\xa0Every meridian is a semi-circle\xa0Each parallel crosses all longitudes\xa0Each meridian crosses all latitudes\xa0To cross all parallels, you have to travel 12,000 miles\xa0To cross all meridians, you have to travel 24,000 miles\xa0Locations with the same latitude do not fall in the same time zone\xa0All locations on the same longitude fall in the same time zone\t | |

Difference between systematic approach and regional approach |
| Answer» Systematic approach was given by Alexander Von Humboldt. In this approach, a phenomenon is studied world over as a whole and then the identification of special patterns is done.Regional approach was given by Karl Ritter. In this approach, the earth is divided into various regions and then the identification of all special patterns is done. | |

Why is the maximum insolation recieved over the sub tropical deserts? |
| Answer» Maximum insolation is received over the subtropical deserts. Equator receives comparatively less insolation than the tropics due to presence of clouds. Generally, at the same latitude the insolation is more over the continent than over the oceans because more clouds over the oceans reflect sun rays back into space. | |

Define ocean currents.How are fishing and oceanic currents related? |
| Answer» The continuous flow of huge amount of water in a definite direction is reffered as Ocean currents.Ocean currents are like river flow in oceans,representing a regular volume of water in a definite path and direction. The mixing of warm and cold currents help to replenish the oxygen and favour the growth of planktons which is the primary food for fish population.Mainly in these zones,the best fishing grounds of the world exist. | |

List the stages in the evolution of the earth and explain each stage in brief |
| Answer» There are three distinct stages in the evolution of the earth :Stage I : In this stage planetesimals accretion happened and the earth originated. It was a barren, rocky and hot object-with a thin atmosphere of hydrogen and helium.Stage II : Development of Lithosphere :(i)The primordial earth was mostly in volatile state. Its density gradually increased, the temperature inside increased. As a result, the material inside started getting separated depending upon their densities.(ii)The heavier materials like nickel and iron sank towards the centre of the earth and the lighter ones moved towards the surface. Over a period of time it cooled and solidified and condensed into a smaller size which later led to the formation of crust.(iii)There was a giant-impact on the earth during the formation of the moon which heated it up further which lead to differentiated layered structure of the earth. Starting from the surface of the earth to the central part, distinct layers like crust, mantle, outer core and inner core were formed.Stage III : Evolution of Atmosphere and Hydrosphere :There are three stages in the evolution of the present day atmosphere(a) Loss of primordial atmosphere containing a thin layer of hydrogen and helium as a result of stripping off by solar winds.(b) The hot interior of the earth : Contributing to the evolution of the earth. The gases were outpoured from the interior of the earth during the cooling of the earth through the process called degassing. This started the evolution of the early atmosphere which largely contained water vapour, nitrogen, carbon dioxide, methane, ammonia and very little of free oxygen.(c) Finally, the composition of the atmosphere was modified by the living world through the process of photosynthesis.Formation of Hydrosphere : The continuous volcanic eruptions contributed water vapour and gases to the atmosphere. As the earth cooled, the water vapour released started getting condensed. The carbon dioxide in the atmosphere got dissolved in rainwater and the temperature further decreased causing more condensation and more rains. The rainwater falling onto the surface got collected in the depressions to give rise to oceans. Thus earth\'s oceans (hydrosphere) were formed within 500 million years from the formation of the earth. The process of photosynthesis was initially confined to oceans only and thus oceans started filling up with the oxygen. Eventually, oceans got saturated with oxygen and the oxygen started to flood the atmosphere. | |

What do you mean by sinkhole |
| Answer» Sinkholes\xa0are just one of many forms of ground collapse, or\xa0subsidence. A sinkhole is a depression in the ground that has no natural external surface drainage. Basically, this means that when it rains, all of the water stays inside the sinkhole and typically drains into the subsurface. | |

What are the igneous rocks |
| Answer» Rocks formed through cooling of magma and also called primary rock<br>Those rocks formed by the cooling and solidification of (magma)molten matter of the earth are called igneous rocks. These rocks were the first to be formed on the surface of the earth. So the are also known as primary rocks.<br>Igneous rocks are those rocks which have been formed by the cooling and solidification of molten natural matter of the earth.The igneous rocks are formed when magma cools and turns into solid forms. The process of the cooling and solidification can happen in the earth\'s crust as well as on the surface. | |

What is the difference between volcanic cone and volcanic plateau |
| Answer» \tA\xa0volcanic cone\xa0is a triangle-shaped\xa0hill\xa0formed as material from\xa0volcanic eruptions piles up around the\xa0volcanic vent, or opening in Earth’s\xa0crust. Most volcanic cones have one volcanic\xa0crater, or central\xa0depression, at the top. They are probably the most familiar type of volcanic\xa0mountain.\tA\xa0volcanic plateau\xa0is a\xa0plateau\xa0produced by\xa0volcanic activity. There are two main types: lava plateaus and pyroclastic plateaus.\tLava plateaus are formed by highly fluid (runny)\xa0basaltic\xa0lava during numerous successive eruptions through numerous vents without violent explosions (quiet eruptions).\xa0\tPyroclastic volcanic plateaus are produced by massive\xa0pyroclastic flows\xa0and they are underlain by\xa0pyroclastic rocks:\xa0agglomerates,\xa0tephra,\xa0volcanic ashes\xa0cemented into\xa0tuffs,\xa0mafic\xa0or\xa0felsic. | |

Write a difference between orogeny and eperiogeny ? |
| Answer» Orogenic forces cause deformation of the Earth’s lithosphere and result in the occurrence of several geological processes. This process is called orogeny and can take place over a period of several million years. As a result, mountains get formed from the seabed or plains.On the other hand, epirogenic forces cause depressions or upheavals of land with long wavelengths and broad ripples. This process is called epirogeny, and the result can be either transient or permanent.\xa0 | |
