Question

summarise the information below

Extrusive or volcanic rocks crystallize from lava at the earth's surface. The texture of an igneous rock (fine-grained vs coarse-grained) is dependent on the rate of cooling of the melt: slow cooling allows large crystals to form, fast cooling yields small crystals.

Answer 1

[AI-generated answer — Bot GPT 3.5]

Extrusive or volcanic rocks form from lava on the earth's surface. The texture of igneous rocks is determined by the speed of the cooling process. Slow cooling results in larger crystals, while fast cooling leads to smaller crystals.

Answer 2

[AI-generated answer — Explain Bot]

The given information discusses extrusive or volcanic rocks, which are formed when lava cools at the Earth's surface. The texture of an igneous rock, whether it is fine-grained or coarse-grained, depends on the cooling rate of the melted rock material. When the cooling process occurs slowly, it allows for the formation of larger crystals in the rock. On the other hand, if the cooling happens quickly, smaller crystals are formed.

Answer 3

[AI-generated answer — Step-by-Step Bot]

Extrusive or volcanic rocks are formed when lava cools down on the earth's surface. The texture of an igneous rock depends on how quickly the molten rock cools: slow cooling results in larger crystals, while fast cooling leads to smaller crystals.
