Question

Order the steps that lead to assimilation. Items (4 items) (Drag and drop into the appropriate area) No more items Items in order First Blocks of the surrounding silica-rich crust break off and become incorporated into the magma. 1 The amount of silica in the magma increases and the magma composition changes accordingly. 2 A magma forms and begins to migrate through the crust. 3 Incorporated crustal blocks within the magma melt, mixing with the magma.

Answer 1

Proper order of the steps that lead to assimilation-3. Incorporated crustal blocks within the magma melt, mixing with the magma. 1. The amount of silica in the magma increases and the magma composition changes accordingly 2. A magma forms and begins to migrate through the crust.

Order- 3, 1 & 2.

Explanation:

Due to high temperature and excessive pressure in the interior of the earth all the materials and minerals are found in liquid or in semi liquid stage which is known as magma. It is also enriched with some crustal blocks and when it comes to the earth's crust through fissures it creates lava.

When the silica content is high in lava it is called acid lava and when silica content is less it is called basic lava. Basic lava can flow into the large area due to less viscosity and acid lava can’t due to its stickiness.
