How old is Australia geologically? How old is the ice in Antarctica? Where did the Atlantic ocean floor come from? How old is Glacier Peak? How old is Earth, according to the geologic time scale? How old is Earth according to the geological time scale?
How old is Australia geologically? How much gold is in the Earth's crust? How many layers are in the Earth's crust? How old is New Zealand geologically? Is the continental or oceanic crust thicker? What are the layers of the Earth's crust?
Although he was by then a wealthy, respected scientist, Darwin thought that Australia might offer his children a brighter future than “old burthened” Britain. (He would eventually have five sons and three daughters who survived beyond infancy.) “Yours is a fine country,” he wrote ...

The youngest heaps are only a few years old while the oldest are more than 100 years old (Woźniak 2010). The region of the Silesian Upland is under the influence of a temperate climate. Here, the main annual rainfall is 600–800 mm and the highest mean temperature in July is 14-16...
it will face one of the most ambitious missions in any space exploration project to date: To search forevidence of life on Mars. If there ever was life on Mars, there almost certainly isn’t now — so how do you go about hunting for evidence of so...
It's a race against time to work out how to grow them before more species – like the Shelford Leek-orchid (Prasophyllum fosteri) from western Victoria, which is now down to only a handful of wild plants – go extinct. Three month old baby leek orchid seedlings. Of the few seeds tha...
(Katoomba, where I live, is about a kilometre above sea level, which ishighfor Australia; this country's pretty geologically inactive, so for a very long time erosion's been wearing the mountains down and nothing's been pushing them up. A thousand metres is still enough to drop atmospheric...
Even the USA, which generally favors road and air for long-distance journeys, has plans for high-speed railroads in California and Texas. Virgin Trains is planning to extend an existing route connecting Miami and West Palm Beach to link up with Orlando as well as upgrading old track to allow...
