Question 3(multiple choice worth 3 points) what is most likely true about a rock that contains small mineral crystals? . the rock is igneous. ii. the rock cooled quickly. iii. the rock cooled on earth's surface. i only il only ill only i and il only i, ii, and li

Option (4)

Explanation:

The igneous rocks are formed due to the crystallization of magma at or below the earth's surface. These rocks are comprised of minerals (crystals) that usually ranges from fine-grained to coarse-grained in terms of size. The size of these crystals are directly related to the cooling rate of magma. If the rate of cooling is fast, then it produces fine-grained crystals. Whereas, if the rate of cooling is slow, then it produces coarse-grained crystals.

The magma when comes out to the earth's surface, it cools immediately. As a result of which coarse grained crystals are formed.

Thus, the fine grained crystals are generally formed in the intrusive igneous rocks such as granite where the finer crystals are formed due to the faster cooling rate of magma.

Hence, the correct answer is option (4).

predicting long term climate trends reliably is much easier than predicting short term weather, owing to the different data sets used for each.
