Rangitoto Island

We've been learning about volcanoes. Here is a report we wrote as a class.

Rangitoto Island

Rangitoto Island is a volcanic island near Auckland city.

Rangitoto Island is 5.5 kilometres wide and is a well-known Auckland landmark.

Rangitoto is a symmetrical shield volcano cone rising 260 metres from the sea. A shield cone volcano is a volcano made up of basalt rich lava, which is thin and runny and spreads a long way from the vent. This makes an island shape that has long gentle slopes. It is also Auckland's newest volcano, it was formed between 600 and 700 years ago. Rangitoto is Maori for Bloody Sky.
