What does underground water do to a volcano?
Groundwater that comes in contact with magma or rocks heated by magma can boil into steam. If it boils quickly enough it can result in an explosion called a phreatic eruption.
What happens when water trapped underground comes into contact with hot magma?
The water will flash to steam, resulting in what is known as a phreatic eruption.
Does the volcanic eruption only affect the land?
No. It also affects the atmosphere by the emission of gasses including some toxic ones, and could cause damage to water bodies when flowing magma comes in contact with the ocean or sea during an eruption, thereby leading to pollution.
What processes found at hot spots will form metamorphic rocks?
Metamorphic rocks at hot spots will form mostly by contact and hydrothermal metamorphism as a result of exposure to heat from magma and interaction with hot water respectively.
Why do igneous rocks form?
Volcanic activity will produce igneous rock.

How water becomes impure?
As it flows above and underground, it comes into contact with rocks and soil, where minerals are eroded of the rocks or soil and dissolve into the water.

The water will flash to steam, resulting in what is known as a phreatic eruption.
What happened in the 1350BC Yellowstone eruption?
The 1350 BC was not a super eruption. The last of those in Yellowstone was 640,000 years ago. Instead it was most likely a phreatic eruption, essentially a steam explosion. This type of eruption does not erupt fresh material from magma. Instead water come in contact with magma or superheated rocks underground and flashes to steam, reulting in an explosion. These eruptions can produce clouds of ash as rocks in or on a volcano are blasted apart.
Can a volcanic eruption occur not including lava?
Yes. Large explosive eruptions do not produce lava, but instead produce clouds of ash, pumice, and gas. There are also phreatic eruptions. These occur when water flashes to steam from contact with magma or rocks heated by magma, generating an explosion.
Where erosion usually happen?
Everywhere water is frequenly in contact with rocks. Like seashores, rivers, underground caves etc...
What is a limitation of geothermal energy?
The hot rocks in a particular place may cool down by the constant contact with cooler water. The geothermal plant may have to stop and wait till those rocks heat up again from contact with the heat from the centre of the earth.
What does sedimentary rocks have to do with water?

How do rocks change water level?
Rocks change water level bye ............................the weight of the rocks makes the water highterr ?
Which rock absorbs water grainy rocks or crystal rocks?
Grainy rocks not only absorbs water better than crystal rocks, but it filters the water as well.
What is the different between phreatic volcanic eruption and a strombolian eruption?
A Strombolian eruption is a type of magmatic eruption, meaning that molten rock actually erupts onto the surface. In a Stombolian eruption gasses trapped in the magma expand explosively, sending fountains of lava into the air. A phreatic eruption does not directly involve molten rock. Phreatic eruptions occur when water comes incontact with magma or hot rocks near magma and turns to steam, creating an explosion. Some ash may be ejected from these eruptions, but this is formed from the explosion blasting old rock rather than fresh magma.
