Question

State the following statements are true or false

1. Quartzite is a sedimentary rock.​

Answer 1

Answer:

true

Explanation:

Answer 2

Answer:

False.

Explanation:

Quartzite is a metamorphic rock made from quartz sandstone, a sedimentary rock predominantly composed of the silicate mineral quartz. The chemical composite of the quartz minerals is silicon dioxide, written SiO2. The metamorphic forces of heat and pressure force the quartz minerals to bind together and crystallize into a strong matrix. This makes quartzite much harder on the Mohs scale (a measure of a rock’s hardness) than its parent rock of sandstone.
