Answer:
C would be the correct answer
The main vent is the main outlet for the magma to escape. Secondary vents are smaller outlets through which magma escapes. The crater is created after an eruption blows the top off the volcano
Answer: Adiabatic temperature gradient is the rate of change in temperature due to pressure under adiabatic conditions.
Explanation:
The rate of change of temperature due to pressure under adiabatic conditions is referred to as adiabatic temperature gradient.
In practice, since in the sea the pressure changes can be considered proportional to depth changes, the adiabatic temperature gradient is usually given as rate of change per unit depth, instead of per unit pressure and for practical purposes and calculations, the unit of depth is often chosen as 1000 m.
The natural and non-natural heat transfer influence the process of adiabatic temperature gradient.
The answer is the spring equinox
They can occur anywhere between the Earth's surface; about 700 kilometers<span> below the surface.</span>
