If the viscosity and the gas pressure are low enough, lava will flow slowly onto the earth's surface when the volcano erupts, with minimal explosion. While these effusive lava flows can reap considerable damage
If the viscosity and the gas pressure are low enough, lava will flow slowly onto the earth's surface when the volcano erupts, with minimal explosion. While these effusive lava flows can reap considerable damage on wildlife and manmade structures, they are not particularly dangerous to people bec...
When a volcano erupts, lava may flow out. How does this lava flow affect the nearby forests? A. It will make the forests grow more luxuriantly because the lava contains a lot of water B. It will completely destroy the forests because of the high temperature and large area of the lava ...
or plates, that fit together like a puzzle. Explain the process of an eruption: When these plates shift, they slide on top of another, pushing a substance called magma between the plates. Magma, which is found between the Earth's crust and the mantle, is called lava when it erupts onto...
If the temperature is very high, the rockmelts. What do we call this melted rock? Magma! So where can we seemagma? In volcanoes! Inside volcanoes, the temperature is over 700℃. Sothe temperature is high enough to melt rocks. When a volcano erupts,magm a comes out. The colour of ...
Thisparticular volcanoerupts with smoke and fire, not lava. If you add iron or aluminum filings to the mixture, you can shoot a shower of sparks. Ketchup & Baking Soda Volcano Ketchup contains vinegar, which reacts with baking soda to produce an extra-special lava for a chemical volcano.Kin...
So what exactly is a volcano? It’s essentially just an opening on Earth’s surface where molten rock that is piped up from the upper mantle pours out. Beneath the Earth’s surface, that molten rock is referred to as magma, but once it erupts, it’s called lava. ...
A common method is to devise a classification of volcanoes based on historical records: if a given type of volcano erupts more frequently after earthquakes, then it is considered more sensitive8,9,16,17. Unfortunately, the limited number of recorded events precludes statistically significant correlati...

Look at our homemade volcano erupt! Add a couple of drops of food coloring to the vinegar. Then pour the colored vinegar into your bottle (using a funnel if necessary) and watch the reaction happen! Why the Volcano Erupts This easy volcano experiment for kids is based on a simple chemical...
