Why does tropical cyclone originate over the seas? In which part of the tropical cyclone do torrential rains and high velocity winds blow and why? |
|
Answer» Solution :At the equator, the Coriolis force is zero and the wind blows perpendicular to the ISOBARS. The low pressure gets filled instead of getting intensified. That is the reason why tropical cyclones are not formed near the equator. Torrential rain occurs in the eye of the cyclone. The strong occurs in the eye of the cyclone. The strong spirally circulating wind AROUND the centre is called the eye. The DIAMETER of the circulating system cna vary between 150 and 250 KM. The eye is a region of calm with subsiding air. Around the eye is the eye wall, where there is a strong spiralling ascent of air to greater height reaching the tropopause. The wind reaches maximum velocity in this region, reaching as high as 250 km per hour. From the eye wall rain bands may radiate and trains of cumulus and cumulonimbus clouds may drift into the outer region. Due to torrential rain, wind blowing from those regions are humid. It brings PRECIPITATION in oceanic regions. Due to torrential rains, heavy rain takes place on eastern coast of India and north east coast of China. |

What makes a river system? Explain its components. |
|
Answer» SOLUTION :River system (a) A river is a body of water, which flows into channel from a higher elevations to a lower elevation rivers usually originate from lake or MELTING snow on top of mountains flow down hill and join sea or ocean. The place from where the river originates is known as the source, and where it ends is known as the mouth. (b) From the source , the river flows along a path which is known as its course. The course of a river can be DIVIDED into three parts, the upper course, the middle course and the lower course. (c) In the upper course, the river flows with great force through a narrow andd shallow channel. Only a small amount of water is transported. The gradient slope of river is very steep. (d) In the middle course, the force of the river reduces its flow through gentle gradient such as PLAINS. Many small stream or river join the main river in the middle course resulting in widening of the river channel. The small streams are known as tributaries. (e) The river finally flows into lake, sea or ocean. The part of the river that enters the sea is known as the river mouth. (f) Ariver and its tributaries together form a drainage basin. A drainage basin is an AREA obtained by two main river and its tributaries and drainage basin is separated from adjacent basins by a hill, a ridge or mountain which is known as a drainage divide or watershed. |

What relationship explained by rock cycle between the major type of rocks? |
| Answer» Solution :Rocks do not REMAIN in their original form for long but may undergo transformation. Rock cycle is a CONTINUOUS process through which old rocks are transformed into new ones. IGNEOUS rocks are primary rocks and other rocks (sedimentary and metamorphic) form from these primary rocks. Igneous rocks can be changed into metamorphic rocks. The fragments derived out of igneous and metamorphic rocks form into sedimentary rocks. Sedimentary rocks themselves can turn into fragments and the fragments can be a source for formation of sedimentary rocks. The crustal rocks (igneous, metamorphic and sedimentary) once formed may be CARRIED down into the mantle (interior of the earth) through subduction process (parts or whole of crustal plates going down under another plate in ZONES of plate convergence) and the same melt down due to increase in temperature in the interior and turn into molten magma, the original source for igneous rocks. | |

Write a short note on Stevenson Screen. |
|
Answer» Solution :The Stevenson screen is designed to protect thermometers from precipitation and direct sunlight while ALLOWING air to circulate FREELY around them. Formation: It is MADE from wood with louvered sides to allow free and even flow of air. It is painted white to reflect radiation. It stands on four legs and is about 3 feet 6 inches above the level ofthe ground. The legs must be SUFFICIENTLY rigid and be buried sufficiently in the ground to prevent shaking. The front panel is hinged at the bottom to form a door, which allows for maintenance and reading of the thermometers. The door of Stevenson screen is always towards the NORTH in the northern hemisphere and towards the south in the southern hemisphere because direct sunrays also affect mercury. Objective: The purpose of the Stevenson screen is to create a uniform temperature enclosure that closely represents the same temperature as the air outside. |

Write about genetic biodiversity? |
| Answer» Solution :Genetic biodiversity refers to the variation of genes within species. Groups of individual organisms having certain similarities in their physical characteristics are called species. Genes are the basic building blocks of various LIFE forms.
