Chalk vs Sandstone

Chalk vs Sandstone Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Chalk and Sandstone Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Chalk vs Sandstone information and Chalk vs Sandstone characteristics in the upcoming sections.

Chalk vs Sandstone Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Chalk vs Sandstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Sandstone. Learn more about Chalk vs Sandstone in the next section.

Chalk is available in grey, white, yellow colors whereas, Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Chalk is Soft and that of Sandstone is Rough. Properties of rock is another aspect for Chalk vs Sandstone. The hardness of Chalk is 1 and that of Sandstone is 6-7. The types of Chalk are Not Available whereas types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk and Sandstone is white. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Sandstone is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Chalk is heat resistant whereas Sandstone is heat resistant, impact resistant, pressure resistant.
