Chalk vs Pumice

Chalk vs Pumice 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 Pumice Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. 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 Pumice information and Chalk vs Pumice characteristics in the upcoming sections.

Chalk vs Pumice 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 Pumice characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Pumice. Learn more about Chalk vs Pumice in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Chalk and Pumice, they have various applications in construction industry. The uses of Chalk in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for manufacture of quicklime and slaked lime, Source of calcium and that of Pumice include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks.

More about Chalk and Pumice

Here you can know more about Chalk and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Pumice consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica.

Chalk is available in grey, white, yellow colors whereas, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Chalk is Soft and that of Pumice is Vesicular. Properties of rock is another aspect for Chalk vs Pumice. The hardness of Chalk is 1 and that of Pumice is 6. The types of Chalk are Not Available whereas types of Pumice are Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk is white while that of Pumice is white, greenish white or grey. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Pumice is 0.87 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 Pumice is impact resistant, pressure resistant.
