Why some currents are warm or cold? |
| Answer» Solution :These are several warm ocean currents that move warm water away from the equator. These currents of water have warm air above the water. The warm air raises the temperature of the land it touches. These areas enjoy a MUCH warmer climate than other places at the same latitude. Areas such as England would be much colder without the warm Gulf Stream. Warm ocean currents flow on the eastern SIDE of a continents. They only reach the western side in high latitude areas. Another characteristic is that they flow away from the equator. Warm currents have higher temperatures, so they are less dense than cold water. Usually warm water has a higher salinity, but it remains less dense than cold water, so cold water is HEAVIER and flows under warm water. The water is warmed on the SURFACE, so warm currents flow across the surface of the ocean. As a warm current cools down, it drops down and becomes a cold water currents. | |

|
| 1807. |
Why is the western coastal plain is devoid of any delta? |
| Answer» Solution :The SLOPE of rivers of western coast is very steep. THEREFORE, these rivers flow not in different parts but in one part. And hence they do not FORM any delta. As a RESULT, we do not FIND any delta in the western coast. | |

Why is there a time variation of 2 hours between the easternmost and westernmost part of the country? |
|
Answer» Solution :Longitudinal extent of India is `68^(@)7.` to `97^(@)25. E-(29^(@))`. There is time variation of 2 hours between eastern most and the westernmost parts of our country. The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat. This is because the earth is tilted and also it rotates in EAST to west direction. So while rotation, the eastern parts of the world experiences the sun rays earlier as compared to the western parts of the world. 1 degree = 4 minutes `"30 degree" = 4 XX 30 = 120` minutes 120 minutes = 2 hours |

Why are parent material and time considered as passive control factors in soil formation? |
|
Answer» Solution :(i) Parent Material: It is a PASSIVE factor in soil formation. Parent materials can be any insitu or on-site weathered rock debris or transported deposits. Soil formation depends upon the texture, structure as well as mineral and chemical COMPOSITION of the rock debris/ deposits. (II) Time: It is the passive controlling factor in soil formation. The length of time the soil forming processes OPERATE determine maturation of soils and profile development. A soil becomes MATURE when all soil becomes mature g processes act for time developing a profile. |

While the pressure gradient force is from north to south, i.e. from the subtropical high pressure to the equator in the northern hemisphere, why are the winds north easterlies in the tropics? |
| Answer» Solution :Rotation of the earth also affects the wind movement. The force EXERTED by the rotation of the earth is known as the Coriolis force. Due to this effect, winds move to the right from their original direction in northern hemisphere and to the LEFT in the southern hemisphere. The deflection is more when the wind velocity is high. The Coriolis force is directly proportional to the angle of latitude. It is maximum at the poles and is absent at the equator. The Coriolis force acts perpendicular to the PRESSURE gradient force. The pressure gradient force is perpendicular to an isobar. The higher the pressure gradient force, the moreis the velocity of the wind and the larger is the deflection in the direction of wind. As a result of these two forces OPERATING perpendicular to each other, in the low-pressure areas the wind blows around it. Therefore, when pressure gradient force is from south to north then winds move from south to north easterlies. | |

Write a detailed note on Tropical monsoon climate (Am). |
|
Answer» Solution :Tropical monsoon climate, occasionally also known as a tropical wet climate or tropical monsoon and trade-wind littoral climate in climate classification, is a relatively rare type of climate that corresponds to the Koppen climate classification category "Am". Tropical monsoon climates have monthly mean temperatures above l8°C in every month of the year and feature wet and dry seasons, as Tropical savanna climates do. Unlike tropical savanna climates however, a tropicalmonsoon climate.s driest month sees less than 60 mm of precipitation but more than (100 - [total ANNUAL precipitation {mm}/25]). Also a tropicalmonsoon climate tends to see less variance in temperatures during the course of the year than a tropical savanna climate. This climate has a driest month which NEARLY always occurs at or soon after the "winter" SOLSTICE for that side of the equator. Tropical monsoon climates are most commonly FOUND in South and Central America. However, there are sections of South Asia, Southeastsia, Africa (particularly West and Central Africa), the Caribbean, ann North America that also FEATURES this climate. |

Without gravity and gradient will there be no erosion? |
|
Answer» Solution :Gravity besides being a directional force activates down slope movement of MATTERS and also causes stresses on earth material. (i) Without gravity and gradients there would be no mobility and hence no EROSION, no TRANSPORTATION and no deposits as gravitation stresses are as important as the other geomorphic PROCESS. (ii) Gravity is force that is keeping US in contact with the surface and it is the force that switches on the movement of all surface material on earth. (iii) All the movement either within the earth or on the surface of the earth occurs due to gradients from higher levels to lower levels and from high pressure to low pressure areas. |

Why Indian gets a monsoon named as south - west monsoon ? |
|
Answer» Solution :(a) The LOW pressure CONDITIONS by EARLY June are powerful ENOUGH to attract the trade winds of Southern Hemisphere coming from the Indian OCEAN. (b) These South - east trade winds cross the Equator and enter the Bay of Bengal and the Arabian sea, only to be caught up in the air circulation over India. (c ) Passing over the equatorial warm currents they bring with them moisture in abundance. (d) After crossing the equator, they follow south westerly directions and they are known as south-west monsoon. |

While the sun rises earlier in the east, say Nagaland and also sets earlier, how do the watches at Kohima and New Delhi show the same time? |
| Answer» SOLUTION :While the sun rises earlier in the east, say Nagaland and also sets earlier but the watches at Kohima and New Delhi show the same time because India FOLLOWS one standard time all over its land. It is time shown at standard meridian of India. There is a general UNDERSTANDING among the COUNTRIES of the world to select the Standard Meridian in MULTIPLES of `7^(@) 30.` of longitude. Hence, `82^(@)30.` E is chosen as the Standard Meridian of India and the time along the Standard Meridian of India passing through Mirzapur is taken as the Standard Time for the whole country. | |

Why are there more earthquakes in the himalayasand in thenortheasternregionof india ? |
| Answer» Solution :Indian plate is moving at a speed of one centimetre per year TOWARDS the north and northeastern direction and this MOVEMENT of plates is being constantly obstructed by the Eurasian plate from the north. As a result of this, both the plates are said to be locked with each other resulting in accumulation of energy at different points of time. EXCESSIVE accumulation of energy results in building up of stress, which ultimately LEADS to the breaking up of the lock and the sudden release of energy causes EARTHQUAKES along the Himalayan arch. | |
