Today, from the reading we leaned how there are different types of stones and how they are being utilized to construct a building. There are three types of building stones and they are: Igneous which is molten, Sedimentary made from water and wind and Metamorphic changes from heat and pressure. There are also different groups of stone such as: granite, which is made from igneous rock, limestone which is made from sedimentary rocks and marble are made of metamorphic rocks. We also learned about how you can built using stone, different patterns of stone, sustainability of stone and durability.
