You are watching: Compare and contrast lava plateaus and dome mountains.
Magma has a lot of trapped gases in it. When the magma go"s towards the surface ar the pressure of the absent on the magma decreases. Dissolved gases begin to broaden into bubbles. Once pressure drops the bubble get bigger. When a volcano erupts expanding gases moved magma from the magma chamber and also will eventually flow or explode. Push on the magma comes from the rock. As soon as magma comes up into the surface push decreases developing bubbles.
Quiet eruptions. Short silica magma run"s easily. Low silica lava can flow for plenty of kilometers. The gases in the magma bubble the end gently which causes Quiet Eruptions.
Dome Mountain- body of hardened magma can produce dome mountain. A dome mountain forms when uplift pushes a huge body the hardened magma toward the surface. The hardened magma pressures the class of absent to bend upward into a dome shape. Lava Plateaus- Lava can flow out that several long cracks in one area. After million of years repeated floods of lava can form high level plateaus. These plateaus are called Lava Plateaus. Compare- castle both type using magma. They space both hardened. They room both formed when lava pushes through the crust.

It deserve to be gases in the magma can come out as warm rock and also ash. They kind a rapid moving cloud the rolls under the sides of a volcano. Over there are likewise damage since of Pyroclastic flow. They can type land slides the mud that can destroy the city. That can damage the crops.
