Explosions from composite volcanoes occur as a result of gas buildup within them. Shield volcanoes also may erupt explosively if water accumulates inside their vents.
What are the options if there are options?
Answer:
The geological process and interactions like earthquakes, volcanic eruption, cyclone etc, are responsible for the changes because these are very fast and sudden.
Explanation:
It is 4.5 billion years that Earth has been formed and there have been changes since then. Earthquakes, volcanic eruption, cyclone etc, are some of the geological process and interactions are the reasons for change in earth's surface. An earthquake usually split or divide the surface into many pieces in a very few seconds. While lava erupted from a volcano makes the land fertile by spreading around within minutes whereas a day of rainfall can lead to a flood in the neighborhoods and results in many losses.
