As magma cools slowly, large coarse crystals form. This is described as a phaneritic texture.

How would you best describe the texture of an igneous rock that formed extremely slowly underground?
Coarse
How would you describe the texture of an igneous rock that formed extremely slowly underground?
An igneous rock that formed extremely slowly underground would likely have a fine-grained texture with small mineral crystals. This slow cooling process allows for the minerals to grow larger and more interlocking, resulting in a strong and dense rock with no visible grains or pores.
What is the textural difference between coarse-grained phaneritic and fine-grained aphanitic rocks?
Coarse-grained phaneritic rocks have large, visible crystals that formed slowly beneath the Earth's surface, giving them a rough texture. In contrast, fine-grained aphanitic rocks have tiny crystals that formed quickly at or near the Earth's surface, resulting in a smooth texture without visible crystals.
Large crystals with well-formed crystal faces tend to form when?
Large crystals with well-formed crystal faces tend to form when the mineral is given enough time to grow undisturbed in a stable environment with plenty of space and nutrients. The slower the cooling or solidification process, the larger and more well-formed the crystals can grow.
How does sandstone turn into granite?
Sandstone does not turn into granite. They are two different types of rocks formed through different processes. Sandstone is a sedimentary rock formed from grains of sand cemented together, while granite is an igneous rock formed from the cooling and crystallization of molten magma underground.

What type of crystal grain is formed when molten rock cools slowly?
Large crystals with a coarse crystal grain texture.

What is the name of the crystal grain that is formed when molten rock cools slowly?
The texture of the rock product of slow cooling magma is referred to as coarse grained.

What is a type of crystal grain which is formed when molten rock cools slowly?
It is mineral
Which will be bigger if one crystal is above and grows quickly and cools slowly and the one underground grows slowly in the warm?
If the crystal grows quickly then it is going to be the quicker one to grow, and thus larger, though not always the most valuable since underground crystals can take millions of years to come to be.
What is formed when a magma chamber cools slowly and hardens underground?
rock because when the lava or magma cools slowly it starts to harden.
What do the size shape and position of the grains that make up a rock determine?
If the grains of the rock are larger, then it either is an intrusive igneous rock,( a rock formed from molten rock that cooled slowly over long periods of time underground) or a sedimentary rock that was formed from large sediments.
What is the crystal size when magma cools entirely underground?
Cooled slowly underground the pseudo crystals of columnar basalt, such as the Giants Causeway in Ireland may be in a metre size range.
What observation about an igneous rock would support the inference that the rock cooled slowly underground?
The rock would have visible mineral crystals--a phaneritic texture.
