2STONEHENGEStonehenge is made up of 2 circular settings of large standing stones, the inner circles stones are 26 feet high and the outer circles stones are 10 feet high.There are two types of stones used in the construction of Stonehenge. The large outer circle is made of Sarsen which is sedimentary Sandstone and the inner circle is made of Bluestone which is a blend of Basalt and Gabbro.It is believed Stonehenge was constructed anywhere between 3000BC and 2000BC.The Stones are said to have been quarried and shaped by workers and then transported to the site. How they were transported still remains a mystery. The stones have been weathered throughout the years by rain and wind.The approximate age of Stonehenge is 5000 years old.Many historians believe several different types of tribes of people built Stonehenge between 3000BC and 2000BC, each building a different phase of it’s construction. Many people believe the first stage was built by the people of the Neolithic Period.

4The Devils MarblesThe devils marbles are 6 huge round red rocks balancing on top of each other. The rocks have diameters of up to 7m.The devils marbles are made out of granite.The granite blocks formed millions of years ago, they have been shaped by years of harsh weather conditions.The Devils Marbles were formed through erosion both wind and rain.
5THE DEVILS MARBLES ARE APPROXIMATELY 1640 MILLION YEARS OLD THE DEVILS MARBLES ARE LOCATED NEAR WAUCHOPE IN NORTHERN TERRITORY.NATIVE ABORIGINALS BELIEVE THE DEVILS MARBLES ARE THE EGGS OF THE RAINBOW SERPENT LAID DURING THE DREAMTIME,TO THIS DAY IT IS CONSIDERED AS A SACRED SITEFOR THE ABORIGINAL PEOPLE.
6GIANTS CAUSEWAYThe rock’s were shaped by an ancient volcanic eruption and they look like hexagonal rock’s.The giant’s causeway is an area of about 40,000 interlocking columns.The tallest are about 12 metres in height.The Giants Causeway was formed approximately million years ago.The Causeway is located in the region of Northern Ireland.
7The Giants CausewayTHE HEAXAGONAL SHAPES OF THE ROCKS ALSO COME IN BUNCHES OF 4’S,5’S & 7,S
8WAVE ROCK Wave rock is made of layers of granite. It is 2,700 million years oldIt is 15m high & 110m long & it look’s like a rounded waveThe rock was formed 2,700 million years agoThe rock’s shape was formed by weathering and water erosion
9WAVE ROCK – WESTERN AUSTRALIA WAVE ROCK IS LOCATED NEAR HYDEN, WA. WATER FROM THE NEARBY SPRINGS RUN DOWN THE ROCKS DURING WETTER MONTHS WHICH HAS FORMED THE SHAPE OF WAVE ROCK. THE COLOURS IN THE ROCK HAVE BEEN CAUSED DUE TO CHEMICAL REACTIONS.
