Q. Consider the following statements:
Both Plutonism and Volcanic Eruption involve cooling of Magma
Both Plutonism and Volcanic Eruption involve bulk chemical changes
Which among the above statements is are correct ?
Answer: Both 1 and 2
Notes: Plutonism refers to the geological process of magma (molten rock) slowly cooling and solidifying beneath the Earth's surface, forming intrusive igneous rocks such as granite. Volcanic eruptions occur when magma and ash are expelled from a volcano onto the Earth's surface. They are caused by the release of pressure within the Earth's mantle or crust. Plutonism and volcanic eruptions are both related to tectonic activity and can occur along plate boundaries or within the Earth's mantle. Plutonism is a slow process that can take millions of years, while volcanic eruptions can happen suddenly and unpredictably.
