Have you ever flicked through a dictionary to find a word, and then noticed that right next to it there is a set of symbols, some of which resemble the letters you are used to using, but some of which are completely different?
These symbols are there to give you a guide to how the word is generally pronounced, and they are part of the International Phonetic Alphabet, or IPA.
In 1864 the French author, Jules Verne, published his novel “Journey To The Interior of the Earth”. In this book 3 men explore volcanic tunnels that lead miles beneath the Earth’s surface, and have a number of strange encounters along the way. One of these is the discovery of a massive ocean, deep underground. Now, 150 years later, it seems that Monsieur Verne’s imagination may have been more accurate than he knew.
An enormous reservoir of water, roughly 3 times bigger than all of the Earth’s oceans put together, has been detected 400 miles below the surface. The water is trapped inside a layer of blue rock called ringwoodite, in the layer of hot rock between the Earth’s core and its surface) that is known as the mantle.
Have you ever let go of a helium-filled balloon and let it soar into the sky? Maybe you’ve even tied a message onto the string, with your contact details and hoped that someone would let you know where it landed when it popped. These awesome girls went a big step further than that. They sent a balloon into SPACE, with a couple of Go-Pro cameras attached, in a really cool science experiment.
