The classic volcano science project could use a few creative upgrades. Jeffrey Coolidge The erupting volcano has long been a science fair staple, but with a few bells and whistles, you can turn it into an even more impressive project. From sparkly explosions to ketchup lava, many have managed to dress up their volcanoes and take it to the next level.
These are some of the incredible effects your report can describe when you discuss volcanoes -- one of Earth's most powerful forces. Why Volcanoes Exist Pressure causes a multitude of physical actions to occur.
Combine heat and pressure and you may create a volcano. Begin your report by explaining how magma -- hot, liquid rock below the earth -- rises because its density is less than the density of the surrounding rocks.
The distance the magma moves vertically depends on factors such as the mass of the rocks it must go through and its density. Under intense pressure, dissolved gas in the magma helps propel it upward where it can make it to the surface and into the air depending on the volcano's type.
Geologists call magma "lava" when it leaves a volcano via an eruption or vent. Define a Volcano's Status According to the Global Volcanism Program, an extinct volcano is one people don't expect to A science report on volcanoes again, while an active volcano is one that has erupted in the last 10, years.
Place these important facts into your report along with the definition of dormant: Helens, a powerful stratovolcano that explodes with fury, hurling gas, rocks and ash high into the air. Shield volcanoes like Hawaii's Kilauea don't erupt as violently -- they create rivers of lava that flow down the mountainside.
Because the lava in shield volcanoes has low viscosity, they erupt less violently, creating gentle slopes around the mountain. Stratovolcanoes have high-viscosity lava, causing them to erupt more violently and form steep-sided slopes.
Magma can also flow from fractures in a volcano without causing an explosive eruption -- scientists call this a "curtain of fire. Submarine volcanoes sit an average of 2, meters 8, feet below the oceans.
According to some theories, over a million submarine volcanoes dot the ocean floor. The continents rest on tectonic plates in motion below the planet's surface.
Explain how you find most volcanoes in places where these plates move away from one another at divergent plate boundaries, or towards one another at convergent plate boundaries.
Hot spots, such as the one beneath Iceland, also create volcanoes. A hot spot is a location where magma has made its way through the Earth's crust. How Volcanoes Affect the World Krakatoa erupted with fury inflinging ash up to 80 kilometers The eruption also created a shock wave that circled the Earth seven times and triggered a massive tsunami that killed over 36, people.
Lava flows are always a concern when volcanoes cause them near populated areas. Explain how lava usually moves too slowly to engulf people, but pyroclastic flows can travel down volcano slopes at up to kilometers Composed of ash and hot gas, these flows kill anything in their path.
On the positive side, tell your readers how volcanoes can create new islands, produce fertile soil, and produce pumice and other useful products.Founded in , Science News for Students is an award-winning online publication dedicated to providing age-appropriate, topical science news to learners, parents and educators.
It’s part of the Science News Media Group, which has published its flagship magazine since A new USGS report, Science for a Risky World: A USGS Plan for Risk Research and Applications, defines for the first time the role of USGS in risk research and srmvision.com includes hazard assessments, operational forecasts and warnings, vulnerability assessments, risk assessments, risk communication, decision-support systems, and post-event assessments.
Whether your volcano is made out of papier-mâché, clay or cardboard, it could probably use some extra creativity. The erupting volcano has long been a science fair staple, but with a few bells and whistles, you can turn it into an even more impressive project.
Volcanoes spew out ash and toxic gases, as well as lava and lava boulders.
Pompeii was an ancient city that was completely buried in ash and lava. Mauna Loa in Hawaii (Pacific Ocean) is the world’s largest active shield volcano standing at 4, m high.
Science >> Earth Science for Kids Volcanoes A volcano is an opening in the Earth's crust where hot liquid rock from deep within the Earth, called magma, erupts to the surface. Pressure causes a multitude of physical actions to occur. Combine heat and pressure and you may create a volcano.
Begin your report by explaining how magma -- hot, liquid rock below the earth -- rises because its density is less than the density of the surrounding rocks.
