Answer:
Their amount is not consistent at all parts of the atmosphere
Explanation:
Carbon dioxide and water vapor exists as variable gases in the atmosphere because their amount varies from one part to the other.
- The abundance of variable gases is influenced strongly by activities from the surface.
- This variability occurs a result of the contribution from from life activities on the surface.
- Also, due to properties of the gases, they are not evenly distributed.
- At certain altitudes, the amount of water vapor can be low.
Well, the cause of a volcanic eruption is when the lower crust melts. This leads to the formation of magma. The volcano is an opening through which the magma is discharged. The rock inside the earth melts. This magma is diffused upwards through the volcano. If magma reaches the top of the volcano, it behaviour depends on viscosity. So what happens before a volcanic eruption is that the lower crust melts, causing the formation of magma, which is released through the volcano. Hope i helped.
