What Happens After an Earthquake?

What Happens After an Earthquake?

People often wonder whether an earthquake can drastically change the topography of a region. A few tremors and some buildings that collapse does not mean that the shape of the earth has changed, does it? However, earthquakes can and do change the topography of the region. An earthquake raised Rhodes island. The line of erosion (on the rock to the left) shows the sea level before the earthquake. The rise is uneven in different parts of the island, usually several meters....

Jacques-Yves Cousteau

Jacques-Yves Cousteau

If there is one person who single-handedly fascinated millions of landlocked viewers to venture underwater into the unknown, through television, it is the Frenchman Jacques Cousteau. Jacques-Yves Cousteau was born on June 11, 1910, in the town of St.-Andre-de-Cubzac near Bordeaux, in France, to Daniel and Elizabeth Cousteau. As a child, Jacques was quite sickly but he nonetheless learned to swim at the age of four. His initial dip led to his everlasting love for the sea....

Why can’t the Sun melt Snow?

Why can’t the Sun melt Snow?

There are some things in nature that have a great capacity to toss back or reflect a great deal of the sun’s light that falls on them. One of them is snow. Newly formed snow reflects about 90 per cent of the sunlight that falls upon it. This means that the sun is powerless to melt clean snow. And when snow does melt, it is not because of the sunlight. Snow does not melt on a spring day because of the sun’s heat....

Why is the Dead Sea dead?

Why is the Dead Sea dead?

The Dead Sea is indeed a very scary name for a lake. It is called so because nothing lives in it. There are no sea weeds or plants, no fish either. This is because the Dead Sea is nearly six times as salty as the ocean. It also contains many other dissolved minerals, including magnesium chloride, calcium chloride and potassium chloride in large quantities. Whereas in fresh water, only minute quantities of these minerals are found....

Himalayas Have a Deep Impact on the Climate of the World

Himalayas Have a Deep Impact on the Climate of the World

Tibet is known as the roof of the world. That is because it is on a region which has the highest altitude in the world. The Himalayan mountain range merges into the Tibetan plateau to form this region known as the Himalaya-Tibetan Plateau. Besides being the roof of the world, this plateau also has a deep impact on the climate of the world, says a report published in the May, 2001, edition of Nature, a science and environment journal....

Why is the Mediterranean Sea Blue?

Why is the Mediterranean Sea Blue?

We know that about seventy one per cent of the earth’s surface is covered with water. The earth’s three main Oceans are the Atlantic, the Pacific and the Indian Ocean. The Atlantic Ocean is a great mass of water that separates Europe and Africa from America. It is shaped like a great hour-glass-with a ‘waist’ where Africa and South America bulge out towards each other. Although in area it is less than half the Pacific, it has many ‘secondary’ seas, such as the Arctic Ocean and the Mediterranean Sea....

My Dream (A Vision Of Peace)

My Dream (A Vision Of Peace)

Where the mountains touch the sky Where poets DREAM, where eagles fly A secret place above the crowd Just beneath a silver-lined cloud. Lift your eyes to a snowy peak And see the soon-to-be we seek Whisper DREAMS and let them rise To the mountains old and wise. Climbers climb, it’s time to try Where the mountains touch the sky Take me there. Oh take me now… Someway, Someday, Somewhere, Somehow! My Dream (A Vision Of Peace) [Illustration by Shinod AP] Where the ocean meets the sky...

The Secrets of the Ocean Floor

The Secrets of the Ocean Floor

It is one question that is not a quizmasters’ favourite: which is the tallest mountain on earth? The answer is bound to come fast and snappy – Mt Everest, at a height of 29,000 feet. But that is only on land. For, if you were to measure from the bottom of the ocean, the tallest mountain in the world will probably be Mauna Kea in Hawaii. It rises more than 15,748 feet under the sea and another 13,779 feet above it....

When will the Oceans of the Earth Overflow?

When will the Oceans of the Earth Overflow?

Try this out. Plug the sink and leave the water running. It will lead to a flood in the bathroom and a scolding for letting the water overflow. Since the sink could not hold an unlimited amount of water, it let the water spill out. But even the oceans are enormous bodies of water that get flooded with water from rain, melting ice, and rivers year after year. Will they start overflowing too? If so, when?...

What is an Earthquake?

What is an Earthquake?

One moment, the world seems just the way it was yesterday, the day before, last year, or even the day before the day before. All is well with the world. It’s a beautiful sunny day and you are sitting drinking your morning tea or coffee relaxed and enjoying the day. Suddenly there is a rattling of plates and glasses. Within seconds chairs and tables are rocking violently, the fans sway crazily and crockery is falling off the shelves....
