Constructive Forces April 24, 2011

Filed under: Uncategorized — mrsdaughertysclass @ 11:55 am

This week I would like you to explore this website and then come back and tell me how you think volcanoes could be a constructive force, that is a force that builds up the earth’s surface!  Be very detailed and try to use big science words in your response :-).  I am sure you could use some of the words we learned about the earth’s structure in your answer.  Be sure to comment on a friends post!

    Volcanoes are a constructive force because they build up the earth’s surface. When a volcano erupts, the lava flows down and creates more crust. Magma collects in the magma chambers and feeds the volcano, then the lava flows onto the land. The lava hardens and it forms on the already existing lithosphere. This makes the land or area around the volcano get thicker and wider. I saw a volcano on the Big Island of Hawaii when I was there. It was in the Hawaii Volcanoes National Park. I saw the black lava rocks and black sand beaches which are made from ground lava. I really liked this website because it let me create my own volcano. It let me see the volcanoes erupt when I set the settings. It was really interesting.

    Volcanoes are a constructive force because, they build up on Earth’s surface. I made a stratovolcano on the website. It has steep sides and can grow in great heights. The volcano I made had a plinian eruption, the most explosive release. A large portion of the top blows off and makes ash and noises that you can hear from hundreds of miles away.

      Christie, I made a stratovolcano on the website aswell, but then I made another and it was a Hawaiian Fire fountain. Well, I love Hawaii and I thought it might be cool to talk about because I’ve been there a few times, and I wanted to learn more about the Hawaiian eruptions!! 😉

    Volcanoes are very simple structures. Earth’s crust is divided into large sections called tectonic plates. There are three different types of volcanoes, cinder cones, stratovolcanoes, and shield. One of the world’s most active zones is the Ring of Fire. The magma chamber holds all the magma in the volcano. If the viscolosity and gas is low, the magma flows down the volcano. If they are high the magma will shoot straight up, flow down, and cause a landslide. Volcanoes can be very destructive to people around it.

      This was a really great description of volcanoes. You used a lot of big science words. I agree that volcanoes can be very destructive, but they are very interesting to learn about.

      me no like big words. But great description about the volcano.

    Volcanoes are a constructive force because they help make up the Earth’s surface. Inside a volcano, there is a hole that stores magma from the Mantle; this is called the magma chamber. As magma fills inside the magma chamber, pressure begins to build and the magma pushes its way up until it eventually reaches the top. The volcano then erupts. The volcano spews out lava and ash on the surface. The lava runs down the side of the mountain and continues on when it reaches the bottom. The ash swells up into a deadly poisonous storm cloud and stretches on for miles. After the ash clears out, the lava hardens into a hard rock called obsidian and creates more land in the process. I thought the website was really cool especially the stratovolcano erupting.

    Volcanoes help build up the land by when magma flows out of a volcan it hardens and makes new crust. There are three different types of volcanoes stratovolcanoes, cinder cones, and shield. The main place where volcanoes are is in the Ring of Fire which is the Pacific ocean. In a volcanoe all magma is held in the magma chamber. As soon as it erupts hot lava pours down the side of the mountain. Depending on the force of the volcanoe it can cause a land slide. That’s what I learned.

    I think that Valcanic eruptions are a constructive force because when the lava hardens and cools it becomes part of the earth. On the website, I created a Hawaiian Fire Foutain. In Hawaiian Fire Fountain Eruptions, streams of lava spray into the air and splash around the valcano’s vent for minutes or hours at a time. First, debris flows out the top. Next, fountains of fire flow out the top (fire fountain). Next, lava flows down the sides of the valcano. Finally, lava sometimes stays hot enough and flows down the lava tubes and slowly drifts away.

  7. Carson Says:

    I think volcanoes are a constructive force because when they explode, they leave rock behind, which happens to build up the Earth’s surface. When the rock cools and hardens, it creates a thin layer of rock. The lava starts out as magma, and is eventually pushed through the crust. When the pressure breakes the rock, the volcano blows its top. When the lava comes in contact with the surface air, it immediately cools and eventually hardens. Then the process is repeated over and over again, adding more rock to the Earth’s surface. Different types of lava come from different volcanoes, like cindercone volcanoes, shield volcanoes, and stratovolcanoes.

  8. Blake B Says:

    Volcanos are constructive forces because they can make islands and hills. The hawaiian islands were made by voldcanos. Volcanos have magma inside but when that magma spews out then it turns to lava. I don’t know why magma and lava have different names but are the same things.

    Volcanoes are a constructive force because they help make up the Earth’s surface. I created a Stratovolcano. This volcano has steep sides and can grow to great heights. When the lava that flows from the volcano hardens and creates more crust. I really enjoyed making the volcano changing the gas and viscosity to create different types of volcanoes.

    I think that volcanoes are constructive because when lava hardens and cools, it becomes part of the crust. On the website, I made a Shield Volcano. A shield Volcano can spread over hundreds of miles out. Here is some of the information I learned from the website…. Earth’s crust is divided into large sections called tectonic plates. There are three different types of volcanoes- cinder cones, stratovolcanoes, and shield. The magma chamber holds all the magma in the volcano. If the viscolosity and gas is low, the magma flows down the volcano. If they are high the magma will shoot straight up, flow down, and cause a landslide. Landslides are very common in California.

    Volcanoes build up the earths surface by the hardening lava from the mantle. On the website i made a volcanoe that created alot of ash

  13. Walker Weldon Says:

    Volcanos help make the earths surface. Inside a volcano deep deep down there is what you would call a magma chamber. When viscosity and gas build up the volcano goes “boom boom”. Once lava explodes it dries to help make the earths crust, thus making volcanos a constructive force. Lets just hope theres not a lot of viscosity and gas or the whole world might be doomed.
