Geography? Some interesting things for "trivial pursuit"

The worlds largest meteorite crater - Two billion years ago a meteorite 10km in diameter hit the earth about 100km southwest of Johannesburg, creating an enormous impact crater. This area, near Vredefort in the Free State, is now known as the Vredefort Dome. It was voted South Africa's seventh World Heritage site at Unesco's 29th World Heritage Committee meeting in Durban in July 2005. The meteorite, larger than Table Mountain, caused a thousand-megaton blast of energy. The impact would have vaporised about 70 cubic kilometres of rock - and may have increased the earth's oxygen levels to a degree that made the development of multicellular life possible. The world has about 130 crater structures of possible impact origin. The Vredefort Dome is among the top three, and is the oldest and largest clearly visible meteorite impact site in the world. The original crater, now eroded away, was probably 250 to 300 kilometres in diameter. It was larger than the Sudbury impact structure in Canada, about 200km in diameter. At 2-billion years old, Vredefort is far older than the Chixculub structure in Mexico which, with an age of 65-million years, is the site of the impact that led to the extinction of the dinosaurs.

World's oldest mountain range?

The Barberton Greenstone Belt in South Africa is estimated at 3.4-3.6 billion years old, and generally regarded as the world's oldest mountains. Their age is indisputedly older than anything in North America (the Appalachians / Blach Hills / Porcupines / Smokies etc) and only Western Australia lays a possible claim. Most geologists accept the Greenstone Belt as being the oldest range on Earth. Some people attempt to dispute the Belt's title by arguing that they are not especially tall mountains. This is a rather absurd attempt. Though they are not especially tall, they are roughly 1000 feet taller than anything in the UK (the Scottish Highlands), taller than the Adirondacks, and at over a mile in height they rise over 4000 feet from the surrounding lowlands. The usual official definition of a mountain ranges from 1000 feet (US) to 2000 feet (UK) - and by all of these this is indisputedly a substantial range. Not tall by world standards - but easily a mountain range. Fossils indicate Bacterial life older than 3 Billion years old in the Range, Gold formed ca 3 Billion years ago, and the range showcases a more complete picture of Earth's geological history than any other Mountain range (indeed many would argue any other region) on Earth.

The coldest place on earth - The site, known simply as Ridge A, is nearly 14,000 metres high and is located deep within the Antarctic Plateau.


I wonder how that was measured? Mount Everest is 8848 metres tall and is thought to be the tallest land feature in the world.

Just checked: Ridge A is 4000 metres high, not 44,000 metres.

The wettest place on earth - Mawsynram, India with a yearly average rainfall of 12 meters. Cherrapunji, is only 16 kilometers away and is in competition with Mawsynram for the wettest place on Earth. Both are situated in North East India in Meghalaya State.

Each town has held the record during the last decade; there's only a difference of 1000 millimeters between the two for each year that goes by. Both are located in the Khasi Hills; which is a contributing factor to their high rainfall.


"Only" 1000mm of difference in rainfall? Doesn't the writer realize that 1000 millimetres is a metre? 39 inches of rain is more than a sprinkle.

Since your talking about trivial pursuit anything about weird dates...like today 09-09-09 ? It could be worse it could be 06-06-06 ! Devil

Well, I'm observing this day in remembrance of 1513 when James IV of Scotland is defeated and dies in the Battle of Flodden Field, ending Scotland's involvement in the War of the League of Cambrai.
