I am looking to do an educational earth science questionnaire on local island here that sits 1.2km off the Coast.
The island is located in Mudjimba, Queensland, Australia and can be seen here: https://www.google.com.au/maps/place/Mudjimba+Island,+Queensland/@-26.6146536,153.1144277,14z/data=!4m2!3m1!1s0x6b937400d6b2349b:0xe3ca9f6aa37d5765
What is being asked is for the participants to answer earth science questions about a location. Please refer to this image to see the location:
So far I have come up with 3 questions (areas identified by numbered boxes on image) and need help with answering them or creating others. Please note that this rock-face is directly opposite the ocean and waves do crash against it when high seas are present.
Q1: What type of rock is this?
A1: Landsborough Sandstone (190 million years old)
Q2: What do you think formed this distinct horizontal formation?
A: (I'm looking for the answer)
Q3: What do you think has formed the rock-face that you are looking at?
A3: Erosion from waves coming up off the sea.
Thanks for any help you may be able to offer.
