Correct option is B
The correct answer is: (B) Quartz
Sand is primarily composed of quartz (SiO₂ - silicon dioxide), which is one of the most abundant and durable minerals on Earth. Quartz is highly resistant to weathering due to its hardness (Mohs scale 7) and chemical stability.
Since it does not easily break down, it remains as the dominant component of sand, especially in riverbeds, beaches, and deserts.
Information Booster:
Quartz (SiO₂) is the most common mineral in sand.
It is highly resistant to physical and chemical weathering.
Found abundantly in igneous, metamorphic, and sedimentary rocks.
Sands rich in quartz are used in construction, glassmaking, and industrial applications.
