Ngatoroirangi The earliest Māori stories speak of a man named Ngatoroirangi‚ a tohunga (high priest) who guided the Te Arawa canoe to this land from Hawaiki‚ the ancestral homeland of Māori. Anxious to explore‚ he and an expedition party‚ travelled east from Maketu‚ down the coast until he reached what is now known as the Tarawera River. Naming it Te Awa-o-te-atua‚ he turned inland and followed it upstream until he reached Ruawahia‚ the central peak of Mount Tarawera. Ngatoroirangi finally

How do volcanoes affect people and environments? Each year there are approximately 50-70 volcanoes that erupt. Those volcanoes affect the people and environments in many different ways. According to the article “How many active volcanoes are there? (Tom Simkin and Lee Siebert) there are about 20 volcanoes erupting right now. Volcanoes can affect people and environments in many uncounted ways. One important thing that can affect the environment is that the volcanic soils help the environment in

of up to 450 mph and the gas can reach temperatures of about 1‚000 °C. They will catch fleeing victims and kill them instantly thus making them a devastating hazard. Volcanic ash is formed during explosive volcanic eruptions when dissolved gases in magma expand and escape violently into the atmosphere. They can also have devastating effects due to the similar heat as pyroclastic flows. They have secondary effects as well‚ such as stopping air travel simply because it is unsafe. Navigation is difficult

natural wonders find their homes in National Parks‚ ranging from Hawaii to British Columbia. Their eruptions occur on mountains on the Ring of Fire‚ when one portion of the earth’s crust slides beneath another‚ and melts under high heat and pressure. Magma erupts from beneath the surface and cause lakebeds‚ mountain peaks and huge boulders. Crater Lake in Southern Oregon at 4‚000 feet is the deepest lake in the nation‚ and was formed when Mount Mazama self-destructed 7‚700 years ago. In the center

The Geological and Biological Origins of New Zealand Introduction New Zealand has a unique landscape with many animals and plants that are native only to itself. The purpose of this essay is to discuss the geological history of the formation‚ as well as the biological origins‚ of New Zealand. It will also discuss how the major land-forming processes of volcanism‚ glaciation and tectonic plates have shaped the country and defined it’s native flora and fauna. Eighty-five million years ago the

Mineral: K-Feldspar K-Feldspar‚ also known as Potassium Feldspar or orthoclase‚ is the most common rock-forming mineral. It covers up about 60% of the Earth’s crust (Feldspar). Feldspar crystalizes from magma which is found in both extrusive and intrusive igneous rocks as well as metamorphic rocks (wisconsingeologicalsurvey.org). They form at medium to high temperature and at certain depths. They may also be found in some sedimentary rocks. This mineral is widespread and can mostly be found

Mineral Lab Paper Week One Mineral Lab Geology SCI/245 Axia College Mineral lab Paper The four requirements for minerals are that they must be naturally occurring in other words they must appear in nature something that that was formed by the earth and not man made. It must be inorganic which means I must not be formed from an organic substance like a fossil of any other living creature. It must have a specific crystalline structure that is formed from simple salts and complex silicates

down the hill and kills every thing in the way. It blocks the way for people to travel. Volcanoes are fractured structured located on the crust which fall within the mass of the definition of planet. The earth allows hot lava to escape from the magma which is below the surface. This occurs when the earth’s crust breaks in some major parts. Erupting volcanoes cause many hazards such as volcanic ash‚ which is a threat to aircraft‚ mainly in jet engines where ash particles are melted due to high temperature
