The individual rock particles, crystals, and sometimes fossils that combine to give a rock its texture are known as ____

The grain size of glassy rocks like obsidian is _______.

Metamorphic rock that contains grains that appear to be aligned in a more or less parallel pattern is__metamorphic rock.

Many young-earth geologists think that the basement rocks created on the third day of Creation were probably ____ rocks

foliated metamorphic rock

Rocks can be classified as igneous, sedimentary, or metamorphic.

Igneous rocks do not make the best building materials because they tend to dissolve in acid rain.
