1.3 Etymology
From old English cealc chalk, lime, plaster; pebble, from Greek khalix small pebble, in English transferred to the opaque, white, soft limestone
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Chalk vs Conglomerate 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 Conglomerate Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix. 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 Conglomerate information and Chalk vs Conglomerate characteristics in the upcoming sections.

Chalk vs Conglomerate 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 Conglomerate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Conglomerate. Learn more about Chalk vs Conglomerate in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes. Due to some exceptional properties of Chalk and Conglomerate, 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 Conglomerate include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone.

More about Chalk and Conglomerate

Here you can know more about Chalk and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Conglomerate consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Conglomerate, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Chalk is Soft and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Chalk vs Conglomerate. The hardness of Chalk is 1 and that of Conglomerate is 2-3. The types of Chalk are Not Available whereas types of Conglomerate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk and Conglomerate is white. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Conglomerate 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 Conglomerate is heat resistant.
