The earths crust is made up of huge slabs called plates, which fit together like a jigsaw puzzle these plates sometimes move which Causes friction and the friction causes earthquakes and volcanic Eruptions. the theory that explains this process is called techonics.

Pressure builds up inside the volcano over time, and when the pressure reaches an extremely high level, it ruptures the ground and outcomes the lava. This will cause an explosive volcanic eruption and the production of pyroclastic material.

Does the lava that forms shield volcanoes probably have a lot of silica or water in it?
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.
Why do shield volcanoes erupt frequently but rarely cause human disasters?
Shield volcanoes erupt lava with a low silica content. There are less dissolved gases and a lower viscocity fluid, so less gas is produced and it takes less pressure to erupt.
Do hurricanes form when there is high pressure or low pressure?
Like other storms hurricane are produce by low pressure.
What effects do volcanoes have on global warming and ozone layer depletionhtml?
Volcanoes do cause global warming and ozone depletion. But the amount is very low.
Does low air pressure cause thunderstorms?
no
What does lava low out of volcanoes?
Because off the pressure.
Can cold weather cause low tire pressure?
yes it can cause low tire pressure
Will low oil pressure cause vehicle not to start?
Low oil pressure in itself will not cause the motor not start. Low oil pressure is a cause for concern as far as motor lubrication. Low oil pressure can cause lubrication failure and be harmful to all moving parts.
Do tornadoes form when there is low pressure?
Tornadoes are themselves small low pressure areas, and generally form with low pressure systems. Most low pressure systems, however, do not produce tornadoes.
Does low pressure cause unsettled weather?
Yes, all storms are formed in low pressure systems, and low pressure systems will frequently cause storms and precipitation.
Are cumulonimbus clouds low or high pressure?
Low Pressure, A Low Pressure Area allows clouds to form, as a result, you can get a storm from a low pressure area.A High Pressure Area is the exact opposite, it doesn't allow clouds to form, you can get sunny weather from this kind of system.
What condition cause deviations from the ideal gas?
High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.
Do clouds form easily when the air pressure is high or low?
Clouds only form when the air pressure is low.
Does the lava that forms shield volcanoes probably have a lot of silica or water in it?
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.
How can low pressure cause a storm to grow?
Since a Low Pressure System allows clouds to form, another thing that I know is that the lower the Air Pressuregoes, the more severe the storm may become.
Why do shield volcanoes erupt frequently but rarely cause human disasters?
Shield volcanoes erupt lava with a low silica content. There are less dissolved gases and a lower viscocity fluid, so less gas is produced and it takes less pressure to erupt.
Do clouds form during high or low pressure system?
low pressure systems
