Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers

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

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

Conglomerate vs Chalk 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. Conglomerate vs Chalk characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Chalk. Learn more about Conglomerate vs Chalk in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Chalk include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Conglomerate and Chalk, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Chalk 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.
More about Conglomerate and Chalk
Here you can know more about Conglomerate and Chalk. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Chalk consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Chalk, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Chalk is available in grey, white, yellow colors. Appearance of Conglomerate is Shiny and Rounded and that of Chalk is Soft. Properties of rock is another aspect for Conglomerate vs Chalk. The hardness of Conglomerate is 2-3 and that of Chalk is 1. The types of Conglomerate are Not Available whereas types of Chalk are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate and Chalk is white. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Chalk is 0.90 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Conglomerate is heat resistant whereas Chalk is heat resistant.
