The Mariana Trench

The Mariana Trench is the deepest part of the world's oceans, and the lowest elevation of the surface of the Earth's crust. It is located in the western Pacific Ocean, to the east of the Mariana Islands. The trench is about 2,550 kilometres (1,580 mi) long but has a mean width of only 69 kilometres (43 mi). It reaches a maximum-known depth of about 10,916 metres (35,814 ft) at the Challenger Deep, a small slot-shaped valley in its floor, at its southern end.

Forecast Equipments

Barometer
=========




A barometer is a scientific instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems, and frontal boundaries.


Anemometer
==========




An anemometer is a device for measuring wind speed, and is a common weather station instrument. The term is derived from the Greek word anemos, meaning wind. The first known description of an anemometer was given by Leon Battista Alberti in around 1450.

Anemometers can be divided into two classes: those that measure the wind's speed, and those that measure the wind's pressure; but as there is a close connection between the pressure and the speed, an anemometer designed for one will give information about both.


Rain gauge
==========



A rain gauge (also known as a udometer or a pluviometer [Pluviograph ] or an ombrometer or a cup) is a type of instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation (solid precipitation is measured by a snow gauge) over a set period of time.

TOBA LAKE FACTS

Lake Toba (Indonesian: Danau Toba) is a lake and supervolcano, 100 kilometres long and 30 kilometres wide, and 505 metres (1,666 ft) at its deepest point. Located in the middle of the northern part of the Indonesian island of Sumatra with a surface elevation of about 900 metres (2,953 ft), the lake stretches from 2°53′N 98°31′E / 2.88°N 98.52°E / 2.88; 98.52 to 2°21′N 99°06′E / 2.35°N 99.1°E / 2.35; 99.1. It is the largest volcanic lake in the world.

In addition, the Toba supereruption (Youngest Toba Tuff or simply YTT[1]) occurred between 69,000 and 77,000 years ago at Lake Toba (Sumatra, Indonesia), and it is recognized as one of Earth's largest known eruptions. The related catastrophe theory holds that this supervolcanic event plunged the planet into a 6 to 10 year volcanic winter, which resulted in the world's human population being reduced to 10,000 or even a mere 1,000 breeding pairs, creating a bottleneck in human evolution. Some researchers argue that the Toba eruption produced not only a catastrophic volcanic winter but also an additional 1,000-year cooling episode.

Food and Talk

Last week at a dinner-party, the hostess asked me to sit next to Mrs Rumbold.
Mrs Rumbold was a large, unsmiling lady in a tight black dress. She did not even look up when I took my seat beside her. Here eyes were fixed on her plate and in a short time, she was busy eating. I tried to make conversation.
"A new play is coming to 'The globe' soon," I said. "Will you be seeing it ?"
"No", she answered.
"Will you be spending your holidays abroad this year?", I asked.
"No", she answered.
"Will you be staying in England?", I asked.
"No", she answered.
In despair, I asked her whether she was enjoying her dinner.
"Young man," she answered, "if you ate more and talked less, we would both enjoy our dinner!".

Am I All Right?

While John Gilbert was in hospital, he asked his doctor to tell him whethet his operation had been successful, but the doctor refused to do so.
The following day, the patient asked for a bedside telephone. When he was alone, he telephoned the hospital exchange and asked for Doctor Millington. When the doctor answered the phone, Mr Gilbert said he was inquiring about a certain patient, a Mr John Gilbert. He asked if Mr Gilbert's operation had been successful and the doctor told him that it had been. He then asked when Mr Gilbert would be allowed to go home and the doctor told him that he would have to stay in hospital for another two weeks. Then Dr Millington asked the caller if he was a relative of the patient. "No", the patient answered, "I am Mr John Gilbert".

One Man in a Boat

Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me.
Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything - not even old boots.
After having spent whole mornings on the river, I always go home with an empty bag. "You must give up fishing!", my friends say. "It's a waste of time". But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all!
