Give a brief description of Zambezi river valley in central Africa.Marks:25
We are in the lap of nature wherever we live, be it in a dense green village or a concrete city. In a sunset everywhere, nature gives a magnificent display of beauty every evening painting the sky with glorious colours. Standing on the peak of a mountain one sees a breathtaking view of natures handicraft as it gouges out a beautiful green valley at the foot with a river flowing through it, dancing to its own tune. Each scenario is completely different yet each has its own splendour, no matter if it is a sunset, a desert, mountain, prairie, lake or ocean.
Man has appreciated nature and still does. Not only is nature beautiful, it is ever changing through different seasons, and has a wild beauty to it. There is a valley in central Africa that when you are there it seems as if you went back in time. This is the Zambezi River Valley that starts in the wetlands of the Okavango swamps. The valley is 1500 miles of wilderness, totally unblemished by mans encroachment. The river flows proudly through the valley. It is a surging force as it goes through rocky rapids, or wide and tranquil where it finds space. On its banks are mud flats and reeds, where crocodiles lie in the sun, and further away dense trees and forests of Mopani trees, interspersed with huge grey prehistoric baobab trees with branches that look like roots. In the day, the sun is a burning yellow fire, and everything droops under it. Even the wild life finds shade and lies down. As the evening comes the setting sun paints the sky with streaks of pink and orange, and the animals like kudus, hippopotamus, bucks, crocodiles and many more emerge.
They come individually or in groups. They carefully approach; stopping to be sure, no predators are near. They dip their heads in the river gracefully to drink. Some suddenly will jump and struggle as a crocodile grabs it and drags it under the water. Elephants come and splash around squirting water over themselves with their long trunks, or rolling in the mud, which is to them a treat.
Lions eventually arrive in a pride, causing the buck to move nervously away. The dusk gives way to the sudden blackness of the night sky studded with silver stars and a small silver moon. Soon the animals were gone; the river flows on into the night.
In the early morning, flowing the river alive and sparkling in the sun, crocodiles basking in the warmth, animals drinking while it was still cool, the river broadened and flowed in channels around green islands. Then it fell down a chasm as a magnificent waterfall, 1708 metres wide. As the river fell down the chasm the sound was as thunder, and water spray rose high in the sky, white like the smoke of a bush fire. The bush is like a tropical forest as the spray rains down on it continually, and it is untouched by man. From here, it flows into a great lake and then to the Indian Ocean.
Give a brief description of a rainbow.Marks:25
Like the sun, the moon and the stars, rainbow is another wonderful work of the mighty sky. Each one of us has seen a band of colours in the sunny sky after rain. A rainbow is delightful natural scenery that is pleasant to eyes. The seven colours of the rainbow (popularly known as VIBGYOR) give a beautiful look to it and they are: violet, indigo, blue, green, yellow, orange and red.
The concept behind the appearance of a rainbow is Refraction of Light. A rainbow is created when white light is bent () while entering a droplet of water, split into separate colours, and reflected back. A rainbow is actually round like a circle. On the ground, the bottom part is hidden, but in the sky, like from a flying airplane, it can be seen as a circle around the point opposite the sun.
A rainbow can be artificially created by spraying drops of water into the air even in a clear sky on a sunny day. We can also see rainbow near waterfalls.
Rainbow is symbolic of peace and harmony in many ancient cultures. We can see people using rainbows as a symbol of happiness in many paintings. Anyone would love a rainbow. Watching a rainbow after a heavy rain is the most beautiful scenery anyone would admire and love to see. Kids love to see a rainbow since it is a colorful scenery. Rainbows give a happy feeling to anyones mind. Simply, a rainbow gives peace of mind and a meaning to hope to people of all ages.
Give a brief description of nature with reference to seasons that keep changing with time.Marks:25
Nature is the most beautiful and integral part of everyones life. Each of us has been blessed with the true love of God in the form of nature. We should never miss the pleasure of enjoying the naturethe aroma of the rain soaked earth during rainfall, white frost on trees and breeze of chilling winter, the blooming of buds and hues of flowers in spring, the scorching heat of the sun during summer. Nature has been the most favourite topic of the works of many famous poets, writers, painters and artists since ages. Nature is everything which surrounds us like water, air, land, sky, mountain, river, forests, animals, birds, plants, the sun, the moon, sea, lake, rain, thunder, storm, etc. Nature is full of colours and has both living and non-living things hiding in its bounty lap.
Everything in the nature has its own power and uniqueness provided by the God. It has its many forms which keep changing with seasons and even from minute to minute such as sea looks bright blue in the morning but by noon it looks emerald green. Sky also changes its colour all through the day from pale pink at dawn, dazzling blue in late morning, bright yellow in afternoon and purple by twilight. Our mood also changes with nature. We are happy and hopeful when it is sun shine, raining or in spring season. We feel heartily happy at moonlight and little bored and tired in harsh sunlight.
Nature has some powerful transformative power which changes our mood and behaviour accordingly. Nature has power to recover the patients from their ailments if they are provided with the pleasant natural environment. Nature is very essential for our healthy life so we should keep it clean and conserve it for our future generations.
