My PBL Volcano Project Report Reflection

This is my PBL Volcano Project. I made it out of chicken wire, a piece of cardboard for the surface of the volcano, paper mache, red cellophane, scouring pads to make the bushes, cardboard for the trees, and I also used blutak to stick the trees onto the volcano, pumice and rocks from home for boulders in the water. This was very fun because it looked awesome at the end.

    My Volcano Report

Introduction

Do you ever wonder why volcanoes erupt or how they form? Well lucky for you this is a report about how volcanoes are formed, why they erupt and what impact the have on the world we live in. This report has great information and 10 awesome facts. So just sit back, relax and enjoy reading my report.

How Do Volcanoes Form

Volcanoes occur where molten rock from many kilometres underneath the Earth’s surface forces its way out above the ground. When it is underground, the molten rock is known as magma. It is lighter in weight than the rock around it, so it pushes up through the surrounding rock, like a beach ball floating up through water, finding the easiest way to the surface. When the magma reaches the surface, it either flows out as lava or breaks up and cools to form ash and small pieces of solid rock. Volcanoes form only in certain parts of the world. In many places there are no volcanoes at all. To understand why, it is important to know about the internal structure of the Earth. Earth has three layers - the central core, a very thick layer called the mantle, and a much thinner layer, called crust. The crust is between 5 and 100km thick.

Volcanoes erupt because of the density and pressure that builds up under the Earth’s surface. When it’s underneath the surface, molten rock is called magma. When it comes up to the surface, it erupts as lava, ash and volcanic rocks. With every eruption, rocks, lava and also ash, build up around the volcanic vent. The type of eruption depends on the magma viscosity, (how thick and sticky the magma is).  The density under the magma is relative to the surrounding rocks and causes it to rise (like air bubbles in syrup). It will rise up to the surface or to a depth that is determined by the density of the magma and the heavy rocks above it.

What Impact Do Volcanoes Have On The World

Positive

• It's good for Farming because it’s good for soil
• It’s good for Horticulture because it helps to fertilize
• It’s good for Stones/Rocks

Negative

• Volcanoes cause destruction and also
• Damage and
• Pollution and also they are
• Harmful to crops animals and oxygen

10 Facts On Volcanoes

The largest active volcano is the Mauna Loa in Hawaii which is over 13,600 feet above sea level.

Mount Fuji is the tallest mountain in Japan and is also a dormant volcano.

The Ring of Fire is a ring of volcanoes that circle the Pacific Ocean. In order for a volcano to erupt, it must be over a hot spot.

The Earth has over 1500 volcanoes.

Eruptions are what cause a volcano to get bigger.

Over 75% of the world’s volcanoes are located in the ring of fire.

Volcanoes can form over mantle plumes which are areas of hot rock under the surface of the earth.

An erupting volcano causes other natural disasters such as earthquakes and tsunamis.

There are three different categories of volcanoes:

Active, Dormant, and Extinct

Volcano Acrostic Poem      

Volcanoes are very morearea because they have lava roto that spits out when the puia erupts

Obsidian is kotahi of the many volcanic kohatu that is in a volcano

Lava spews out the runga of a volcano when the puia erupts

Chalcedony is kotahi of the rocks that comes out o a volcano

Andesite is te volcanic orite of diorite

Not only is reira lava, but in a volcano reira is magma

Only Pungapunga is made by trapped Hau in lava when it cools
