The metamorphic rock with garnet crystals would have formed at a deeper level in the Earth's crust compared to the one with chlorite crystals. Garnet is a high-pressure mineral that forms under conditions of high temperature and pressure, typically found deeper in the crust. Chlorite, on the other hand, is indicative of lower-grade metamorphism and forms at shallower depths. Therefore, the presence of garnet suggests a rock that has undergone more intense metamorphism at greater depths.
the deeper into earth crust the higher the pressure that forms metamorphic rocks

Gabbro has larger crystals, meaning it had much more time to solidify from magma underground. Larger crystals in igneous rock are an indication of longer cooling times, which result in larger crystal growth.
Large crystals found in a fine-grained rock can indicate that the rock cooled slowly, allowing the crystals to grow larger. This slow cooling process typically occurs deeper within the Earth's crust where temperatures are higher. The presence of large crystals in a fine-grained rock can also suggest that the rock underwent metamorphism, changing its original composition.
A piece of granite can be changed from an igneous rock to a sedimentary rock, and then to a metamorphic rock as it gets buried deeper within the Earth's crust.
Garnet is indicative of deeper metamorphism than chlorite.
The igneous rock gets pushed deeper and deeper and slowly turns into lava or magma and slowly cools into metamorphic rock.

Metamorphic rocks are rocks which have been changed by heat an pressure. The deeper you go within the earth, the more heat and pressure there is, which is why metamorphic rocks form there.

The presence of tiny crystals in igneous rock indicates that the rock cooled quickly, resulting in the formation of small crystals. This suggests that the rock likely formed near or at the Earth's surface, like in a volcanic eruption. Rocks with larger crystals usually form deeper underground where cooling is slower.

metamorphic grade and is typically formed at a deeper depth within the Earth's crust. This results in gneiss having a coarser texture and exhibiting stronger foliation compared to slate. Additionally, gneiss is composed of different minerals that have undergone more intense metamorphic changes than those found in slate.
Their surface is often quenched by the sea water so often at the surface they are, crystals will grow and be visible deeper in the rock.
Large crystals in an igneous rock suggest that the rock cooled slowly, allowing for the crystals to grow to a larger size. This slow cooling process typically occurs deeper within the Earth's crust or in a magma chamber, resulting in the formation of coarse-grained rocks such as granite or diorite.
