Question: 1 / 400

Which phrase describes the properties of granite?

Soft and fragile rock.

Hard and coarse rock.

Granite is classified as a hard and coarse rock primarily due to its mineral composition and formation process. This type of igneous rock is formed from the slow crystallization of magma beneath the Earth's surface, allowing large crystals to develop. The presence of minerals such as quartz, feldspar, and mica contributes to its toughness and durability, making granite resistant to weathering and erosion. Its coarse texture is observable in the visible grains of these minerals, which can often be seen with the naked eye. This characteristic makes granite a popular choice for applications like countertops and construction materials, as it can withstand heavy use and is not easily scratched or broken.
