Discuss their similarities and differences between these rocks.

How can these rocks be classified?

Igneous Sedimentary Metamorphic

Lesson objectives: • To know and recognise three types of rocks. • To describe and explain how each type is created. • To determine why one famous landform was formed.

• Igneous - Igneous rocks are formed from cooled lava. They may have crystals, air bubbles or a glassy surface. They can also appear hard and dense • Metamorphic - Changed by heat and pressure, sometimes split into many layers that look like a stack of pancakes with different mineral grains running through the rock. • Sedimentary - Often formed from mud or sand settling at the bottom of water. The rock may contain fossils, have wavy horizontal lines, layers, grains you can see or be dusty.

Different rock types 1) How are Igneous, Metamorphic, Sedimentary rocks formed? Draw a diagram of each and example of each. Try to use as many key words in your answer as possible!

Can you think of any famous rocks around the world?

Uluru or Ayers Rock Large sandstone rock formation located in the middle of the Australian Outback.

How did Uluru form? https: //www. youtube. com/watch? v=k. Ksx. COgih. L 8

How did Uluru form? 550 million years ago the Petermann mountains caused rainwater to flowed down, eroding sand rock and dropping it in big fan shapes on the land. Around 500 million years ago, the whole area became covered in sea. Sand mud fell to the bottom and covered the seabed, including these fans. The weight of the new seabed turned the fans into rock. The sandy fan became sandstone.

How did Uluru form? 400 million years ago, the sea disappeared. Rocks folded and tilted as the earth’s tectonic plates shifted. Over the last 300 million years, the softer rocks eroded away, leaving the spectacular forms of Uluru and Kata Tjuta behind.

Different rock types 2) Where is Uluru located? 3) What type of rock is Uluru? 4) How was Uluru formed? Use some of the following terms. • 550 million years ago: Petermann Mountain range. Rainwater • Erosion • sand • 500 million years ago: covered by sea. • 400 million years ago: sea disappeared. • Tectonic uplift • 300 million years ago: erosion

Plenary: This rock is sacred to the Aboriginals They don’t want people to climb their sacred rock but many tourists do. Would you? Why/Why not? The climb will close for good on 26 October 2019. In November 2017 the land-mark decision was made by the Traditional Owners of this land the Uluru-Kata Tjuta National Park Board to close the climb for good. Effective 26 October 2019, marking the 34 th anniversary of the Uluru hand-back, the climb will be closed.

In your groups: Number 1: Describe to your group what Igneous rock is Number 2: Explain how metamorphic rock is formed to your group Number 3: Tell your group what sedimentary rock is Number 4: Describe how Uluru was formed to your groups (Number 5: Tell your group some interesting facts about Uluru Number 6: Explain to your group how Uluru could be called an adventure landscape)
