There are a few reasons for this. First, the amount of lava on a volcano during an eruption is small compared to the volume of the volcano itself. For a large volcano the effect would be rather like puring a boucket of water on an iceberg. Second, in order to melt, the rock must first be greatly heated up as, compared to the lava, they are freezing cold. All of this heat must be lost by the lava, which cools as a result. In addtion, lava on the surface is also loosing heat to the air. Third, if you look at the temperatures, the lava is actually closer to solidifying than the rock is to melting. The largest mass of molten rock, called magma when it is underground, is usually stored in a magma chamber a few miles beneath the volcano. Some of the surrounding rock may melt and become part of the magma, but this usually does not spread too far as rock is a poor conductor of heat.
Probably from the earthquake that happened when the crater hit the earth. The lava rushes to the surface, melting the crater, and it forms a volcano.
concrete and iron since they have a very high melting point.
There is no volcano that produces white lava naturally. Lava typically appears red, orange, or black due to the presence of various mineral impurities and the melting of rocks. However, artificial conditions can be created in laboratories to produce white lava as part of scientific experiments.
Yes, the cooling of lava from the volcano creates the process of metamorphism; in this case - the rock.
A lava flow is where lava flows down the side of a volcano.
Yes, lava is on the outside of a volcano. Magma is on the inside of a volcano.
yes. magma is the lava that is in the volcano and lava is the magma that is outside a volcano
stinky lava and puny volcano
I lava you!!
What did the BOY VOLCANO say to the GIRL VOLCANO? Answer: I LAVA U
Lava. When the lava comes out of the volcano, gravity pulls the lava down the cone of the volcano, and depending the the viscocity of the lava, it forms a 'cone' or 'shield' as it cools. Thinner lava forms a shield volcano; thicker lava forms a steeper cone shape.
Yes lava flows from a shield volcano.
