|WHO STUDIES THE EARTH ?|
A geoligist reconstructs the story of our planet by studying the structure of Earth's Crust and all that happens as a result.
A geophysicist studies all teh natural happenings (phenomena) whcih take place in the atmosphere, on the Earth's surface and incside the planet.
A geopgrapher studies and maps out Earth's natural features-- mountains, rivers , lakes etc. and man-made additions , such as roads, bridges and canals.
WHAT ARE THE MOST PRECIOUS STONES?
When the magma cools, the material which it contains solidifies in the form of crystals. Precious stones (or "gems") are crystals with particular characteristics of colour, hardness and the way they can reflect the light. They are cut in such a way as to highlight these qualities and are used in making jewellery.
HOW THE HEIGHT OF A MOUNTAIN MEASURED?
To measure the height (or altitude) of a mountain, we take the surface of the sea as a point of reference. When we say, for example, that the mountain K2 is 8618 km a.s.l (above sea level) we refer to the distance between the top of the mountain and the surface of the sea.
