Drag the following in the correct order of new crust formation
Formation of new crust in order:
1. Partial melting of the mantle: The mantle beneath the Earth's surface undergoes partial melting due to heat and pressure.
2. Movement of magma: The molten rock or magma from the partially melted mantle rises towards the surface through cracks and fractures in the crust. This movement is driven by differences in density and convection currents in the mantle.
3. Intrusion and solidification: As the magma reaches closer to the crust, it can intrude into existing crustal rocks, creating intrusive igneous features like dykes or sills. The magma cools and solidifies, forming new igneous rocks.
4. Volcanic activity: If the magma reaches the surface, it erupts as lava, gases, and volcanic ash. This volcanic activity can result in the formation of new crust through the accumulation of layers of solidified lava and volcanic ash.
5. Solidification of lava and volcanic ash: The erupted lava and volcanic ash cool and solidify on the surface, forming new igneous rocks. Over time, these rocks can accumulate and contribute to the growth of new crust.
6. Crustal accretion: The process of new crust formation is continuous over geological time. The newly formed igneous rocks can become part of the existing crust through accretion, where separate pieces of crust are added together.
Note: It is important to mention that the formation of new crust is a complex and ongoing process influenced by various geological factors and plate tectonics. The above order describes the general sequence of events, but the actual process can vary in different geological settings.
