Answer:
1968.85 meters
Explanation:
The Lifting condensation level (LCL) is defined as the height at which a parcel of air is completely saturated i.e the relative humidity of the air parcel reaches a 100%. All this must occur through dry adiabatic lifting.
At sea level, the pressure is given as 101.3kPa
air parcel temperature = 24°C
dew point temperature = 8°C
Using the LCL calculator, the pressure at which saturation occurs to the air parcel is 79.92KPa.
NB: LCL occurs through dry adiabatic lifting whereby the pressure on the air parcel reduces with height.
Using the hypsometric formula We can now convert the pressure into height
h = ((p1/p)^1/5257)-1 X (T + 273.15))/0.0065
where h= height, p1= Sea level pressure, p= atmospheric pressure, T = air temperature
h = ((101.3/79.92)^1/5257)-1 X (4+273.15))/0.0065 = 1968.85 meters

The answer is A. and B.
Let's look into the options one by one:
A. pressure and heat built up in the magma chamber
This is true as the pressure and heat built up is what cause the magma to be pushed out of the chamber through the vent. The higher temperature it is,the more it expands and the more likely it is to erupt.
B. plate tectonics and subduction
This is also true as volcanicity is caused by plate tectonics such as subduction. When the plate bends, cracks are formed which coul then be filled by magma and cause fissure eruption, afterwards forming volcanoes.
C. ground swelling and foreshocks
These are the consequences of volcanic eruption but not the causes and therefore is not true.
D. foreshocks and aftershocks
These are as well the consequences of volcanic activity like above and is not true.
Therefore the answers are A. and B.
Hope it helps!
Is this a multiple choice or what? i think a if it is
I think the answer is D. Violence only when absolutely necessary he said that there is violence is never necessary.
