Responses lava cooling almost instantly when it reaches the surface lava cooling almost instantly when it reaches the surface magma taking an extremely long time to cool underground magma taking an extremely long time to cool underground lava cooling relatively slowly upon reaching the surface lava cooling relatively slowly upon reaching the surface magma solidifying via exposure to intense pressure

Answer 1

A pegmatitic texture in igneous rocks, which features very large crystals, is formed when magma cools slowly underground, resulting in intrusive or plutonic rocks like granite.

Step-by-step explanation:

The scenario that will most likely result in the formation of an igneous rock with a pegmatitic texture is magma taking an extremely long time to cool underground. A pegmatitic texture is characterized by very large crystals, indicating that the magma had enough time to cool slowly and allow the crystal grains to grow to a substantial size. This slow cooling process occurs when magma is trapped beneath the Earth's surface, leading to the formation of intrusive or plutonic igneous rocks, such as granite.
