Match each rock with the correct description. 1. made from a dissolved mineral called calcite sandstone 2. made of large grains of sand quartzite 3. made of very tiny grains of clay shale 4. formed from sandstone basalt 5. fine-grained rock with few or no crystals limestone

Explanation:

1. made from a dissolved mineral called calcite       limestone

Limestone is a sedimentary rock derived from precipitation of the mineral calcite from a solution.

2. made of large grains of sand                                 sandstone          

Sandstone is a sedimentary rock derived from aggregates of sand grains.

3. made of very tiny grains of clay                             shale

Shale is a sedimentary rock made from very fine grain of clay minerals.

4. formed from sandstone                                          quartzite

Quartzite is a metamorphic rock derived from a protolith of sandstone. When sandstone is subjected to pressure and temperature beyond that of metamorphism.

5. fine-grained rock with few or no crystals              basalt

Basalt is an igneous rock dark in color and fine grained.
