Rangitoto -The Volcano Rangitoto first erupted and first appeared about 600 years ago and is now considered inactive. It is still younger than the other active volcanoes which have been erupting a lot longer than Rangitoto has been around.
Magma and Lava - Lava is called magma when its below earth's surface, and when magma is outside the volcano its called lava.
Pumice - Pumice is a a volcanic rock, produced when lava with a very high content of water and gases is discharged from a volcano. As the gas bubbles escape, the lava becomes foamy. When this lava cools and hardens, the result ends up with a very light rock material with tiny bubbles with gas.
Obsidian - Obsidian, igneous rock occurring as a natural glass formed by rapid cooling of viscous lava from volcanoes. They were very useful for the early Maori used as knifes and tools.
Volcano Extinction - Scientists can be confident if a volcano hasn't erupted for 10,000 years, it won't erupt again.
Maungarei/ Mt Wellington - Maungarei has recently passed it's 10,000 year mark. It is now safer for people to explore.
The next volcano eruption - Volcanologists tells us that the next erupted will happen soon, but they don't know where or when. Luckily we will get a warning! EQC and Emergency Services Civil Defence have more information on their websites.
Signs of a volcano erupting - A sign that a volcano might be erupting is when a earthquake happens, it happens when magma rise up and push the land apart so it can get through. It may cause earthquakes.
Axolotl
-Introduction
Axolotls (Ambystoma mexicanum) are gilled amphibians. They are unmetamorphosed larvae of the Mexican salamander. Axolotls have a cartilaginous skeleton that, even in larger, older axolotls, doesn't become completely calcified. Their muscles are similar to those of fish.
-Life Cycle
Their mothers lay multiple eggs at a time. It takes 15 days for them to hatch out of their eggs.
-Diet
They eat mollusks, worms, insects, larvae, crustaceans and some fish. Axolotls are predators.
-Lifespan
Axolotl’s lifespan is only to up to 15 years. You can keep them as pets just don’t, put your finger in the aquarium because they might bite.
-Critically endangered
They are critically endangered because of the pollution in Mexico.
-Appearance
They look like salamanders with antlers and pink. Maybe a frog + platypus + salamander
-Habitat
They live in the Lake Xochimilco in the Valley of Mexico, Since it’s polluted they have to move.
