David Attenborough, Lost World: Magic in the Rock | BBC Documentary

This is a very interesting documentary on fossils and rocks and how it all works. i highly recommend to watch this as i learned loads and im sure you will to

There are three types of rocks. Igneous, metaphoric and sedimentary rocks, I am going to go through all three of these rocks and tell you a bit of information about them.  Igneous – These rock are made by mantle cooling. The earth is made of igneous rocks, basalt and carbonite are two examples of igneous rocks.  Metaphoric- this is when a rock is changed by applying either heat of pressure of both. Marble and slate are two examples of a metaphoric rock.  Sedimentary – this is when layers of material build up over thousands of years and become rock. Sandstone and limestone are two example of this.

For thousands of years, people have depended on stone. During the Stone Age, most people depended on stone completely for hear, shelter and hunting animals. The main stone they used was flint. With flint they could start a fire easily and make very sharp arrow or spear heads for hunting. Flint is usually dark grey, black, and green, white, or brown in colour and usually quite small when found. Flint is a hard form of form of the mineral quartz. It was used as spears and arrows because it could be sharpened easily by cutting thin slivers off it and because it is a very hard stone. Flint has been used as a building material for thousands of years also, it was used to build the Burgh Castle in Norfolk and it is still used to the present day. Flint is common in most areas in Ireland.

One of the most historic building in the world is newgrang in Co, Meath Ireland. it is known from its incredible enginering it took to make it, and guess what it is made of...??? yes you guessed it, it is made of stone.

Have you ever thought what loife would be like if there was no rocks? I am guessing not but its worth a little thought. there would be no roads, building made of stone, stown sculptures , tombstone and and no Gemstown jewwelery.

Most of the ocean floor is made of basalt. This igneous rock continues to flow out of Earth from chains of underwater volcanoes known as “mid-ocean ridges.” I got this fact from a website called "fact monster"

Did you know that rubies are one of the most popular gemstones today. beating mica and amber.
