5.1 Formation

Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

Chalk vs Andesite 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 Andesite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. 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 Andesite information and Chalk vs Andesite characteristics in the upcoming sections.

More about Chalk and Andesite

Here you can know more about Chalk and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Andesite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Andesite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Chalk is Soft and that of Andesite is Dull and Soft. Properties of rock is another aspect for Chalk vs Andesite. The hardness of Chalk is 1 and that of Andesite is 7. The types of Chalk are Not Available whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk and Andesite is white. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
