Volcanic eruptions are catastrophic events that can lead to loss of life. Which measure should people living
near the region of an active volcano take to minimize the loss of life?
Use seismographs to predict volcanic eruptions.
Install devices to monitor the levels of gases emitted by the volcano.
Build houses with no vents to avoid contact with lethal gases.
Build tall houses with steel reinforcements to withstand tremors.
Explain Please

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
