When all the grains in a rock are large and easy to see, the rock is described as

Rather than splitting apart evenly, most minerals have a characteristic type of

As layers of sediments are deposited, the process of _?_ presses them together.

Dissolved minerals and particles stick together to form sedimentary rock in a process called

The color of a mineral's powder is called its

A sedimentary rock used in making concrete is

Marble and quartzite are _?_ because their mineral grains are not in parallel layers or bands.
