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 ...
How a Volcano EruptsA volcano is any opening in the Earth’s surface that allows molten rock and volcanic gases to escape from far below the Earth’s surface. Although many volcanoes are mountainous in shape, a volcano can exist in nearly any form, including volcanic vents on the ocean ...
M:Great,Mary!I know you will enjoy this.Did you know when the volcano erupts,our seats shake?I heard it is quite an experience.Look at the people getting off the ride.They look very satisfied.W:I'm sorry,but I don't think I can do this,even for pizza.How would you feel if I ...
When the pressure gots very high, tho gas explodes out ofthe ground. The magma that comes out of the vokcano is called lava. The volcano eruptsagain and again, and the lava builds up to form a mountain Sometimes many years passbetween erupticns.Land can also be shaped by erosion. ...
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...
In some instances, the magm a ascends into the crust and remains there in large pools, but on other occasions, the magm a reaches the surface and erupts. The place where the lava, as magm a is known when it is on the surface, emerges from,often in a violent manner, is a volcano...

When a volcano erupts,magma comes out. The colour of magma is red, but when magma is cooledand becomes solid rocks, it becomes black.句型解读So the temperature is high enough to melt rocks.因此温度足够高去熔化岩石。be . enough to .足够……去…e. g. She is clever enough to solve ...
When a volcano erupts, sulphur dioxide is released into the atmosphere, where it turns to sulfuric acid. Acid levels in the Greenland ice sheet are helping researchers study volcanic eruptions and their effects on climate. Example: Krakatau (near Java & Sumatra); Tambora (in the East Indies)...
