> > **What is a volcano?** > A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lava fragments. Eruptions can cause lateral blasts, lava flows, hot ash flows, mudslides, avalanches, falling ash and floods. Volcano eruptions have been known to knock down entire forests. An erupting volcano can trigger tsunamis, flash floods, earthquakes, mudflows and rockfalls. > > > **How are volcanoes formed?** > Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger. > > **Why do volcanoes erupt?** > The Earth's crust is made up of huge slabs called plates, which fit together like a jigsaw puzzle. These plates sometimes move. The friction causes earthquakes and volcanic eruptions near the edges of the plates. The theory that explains this process is called plate tectonics. > > > **What are plate tectonics?** > The theory of plate tectonics is a interesting story of continents drifting from place to place breaking apart, colliding, and grinding against each other. The plate tectonic theory is supported by a wide range of evidence that considers the earth's crust and upper mantle to be composed of several large, thin, relatively rigid plates that move relative to one another. The plates are all moving in different directions and at different speeds. Sometimes the plates crash together, pull apart or sideswipe each other. When this happens, it commonly results in earthquakes. > || Continental Drift: **To see this animation again, just refresh this page!** This animation shows you what our planet looked like millions of years ago and what it looks like now! (Graphic Credit: Geology Department at University of California, Berkeley) || > **How many volcanoes are there?** > There are more than 1500 active volcanoes on the Earth. We currently know of 80 or more which are under the oceans. Active volcanoes in the U.S. are found mainly in Hawaii, Alaska, California, Oregon and Washington. > > > ** What are the different types of volcanoes? ** > Volcanoes are grouped into four types: cinder cones, composite volcanoes, shield volcanoes and lava volcanoes. > || > Composite Volcanoes || Composite volcanoes are steep-sided volcanoes composed of many layers of volcanic rocks, usually made from high-viscosity lava, ash and rock debris. Mt. Rainier and Mount St. Helens are examples of this type of volcano. || > || > Shield Volcanoes || Shield volcanoes are volcanoes shaped like a bowl or shield in the middle with long gentle slopes made by basaltic lava flows. Basalt lava flows from these volcanoes are called flood basalts. The volcanoes that formed the basalt of the Columbia Plateau were shield volcanoes. || > || Lava Volcanoes || Lava domes are formed when erupting lava is too thick to flow and makes a steep-sided mound as the lava piles up near the volcanic vent. The eruption of Mount St. Helens in 1980 was caused in part by a lava dome shifting to allow explosive gas and steam to escape from inside the mountain. || > **What is the difference between lava and magma?** > Magma is liquid rock inside a volcano. Lava is liquid rock (magma) that flows out of a volcano. Fresh lava glows red hot to white hot as it flows. > > > **Why does lava take a long time to cool down?** > Lava cools slowly because lava is a poor conductor of heat. Lava flows slow down and thicken as they harden. > > **What is the largest active volcano?** > The world's largest, active volcano is Mauna Loa in Hawaii, where famous coffee is grown in the rich volcanic soils. Mauna Loa is 13,677 feet above sea level. From its base below sea level to its summit, Mauna Loa is taller than Mount Everest. > > > **What is the Ring of Fire?** > The Pacific Ring of Fire is an area of frequent earthquakes and volcanic eruptions encircling the basin of the Pacific Ocean. The Ring of Fire has 452 volcanoes and is home to over 50% of the world's active and dormant volcanoes. Ninety percent of the world's earthquakes and 81% of the world's largest earthquakes occur along the Ring of Fire. >

DID YOU KNOW = week five = What are the layers of the earths structure?

dimonds and lloootttsss more eg:coal dirt rock gems and gold
 * What resources do we use from beneath the earth? **iner core outercore then the mantel the crust lots of dirt then the atmosferr and the ow zone layer then space

thiss week i learnt about earths resorces what we use frome deep below the earth as well a heap more about earth

 * What effect does the sun and moon have on the Earth?

the suns main job is to keep earth in it place and to warm the days the moons is a heap of rock that circles earth

this week i hare been learning about volcanoes there are a range of different volcanoes shield volcanoand and more we needed to** memorise it then write it down

tornoto expirment

MATERIALS: PROCESS: Fill one of the bottles two-thirds full of water. Take the Tornado Tube and twist it on the first bottle. Then, grab the second bottle and attach it to the Tornado Tube. Or use duct tape to fasten the two containers. Make sure to tape tightly to make sure that no water will leak out when you turn the bottle over. Turn the tornado maker, so that the bottle with the water is on top. Swirl the bottle in a circular motion. Most tornadoes form counter-clockwise in the Northern Hemisphere. A tornado will form in the top bottle as the water rushes into the bottom bottle. = =
 * 2 2-liter clear plastic pop bottles (empty and clean)
 * water
 * duct tape or you can purchase a Tornado Tube at the Weather Wiz Kids® Store that will connect the 2 2-liter bottles together
 * If you want to get creative, you can also use food coloring to make the tornado have a color and glitter to represent debris.

What is a hurricane? A hurricane is a huge storm! It can be up to 600 miles across and have strong winds spiraling inward and upward at speeds of 75 to 200 mph. Each hurricane usually lasts for over a week, moving 10-20 miles per hour over the open ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power. Hurricanes rotate in a counter-clockwise direction around an "eye." The center of the storm or "eye" is the calmest part. It has only light winds and fair weather. When they come onto land, the heavy rain, strong winds and large waves can damage buildings, trees and cars. ||~  || this is lachlans pouws page ||   ||

Hurricanes only form over really warm ocean water of 80°F or warmer. The atmosphere (the air) must cool off very quickly the higher you go. Also, the wind must be blowing in the same direction and at the same speed to force air upward from the ocean surface. Winds flow outward above the storm allowing the air below to rise. Hurricanes typically form between 5 to 15 degrees latitude north and south of the equator. **
