There are three major classes of rocks , categorized by their formation: igneous, sedimentary, and metamorphic rocks. They are further divided into various groups and types based on their chemical, mineralogical, and textural differences. Igneous rocks are formed either within the Earth (magma that solidifies underground) or with lava spewed from volcanoes and solidifying on the surface. Common examples are granite, basalt, and pumice. Sedimentary rocks are formed from layers of sand, silt, animal skeletons, and dead plants. Some common types are shale, chalk, sandstone, and banded iron. Metamorphic rocks are the result of changes in existing underground rocks. These changes occur due to the impact of temperature, pressure, or chemicals. Widely known rocks include marble (a metamorphosed limes...

However, the organization changed its status to “vulnerable” in 2017 after finding errors in the 2008 Population assessment. The current estimated population of snow leopards is up to 10,000 adults in the wild. China , with an estimated population of over 2,000 individuals, has the largest population of snow leopards. Several factors have declined the population of snow leopards. The biggest threats are hunting for illegal animal trade of their hides and bones, killing by herders to protect their livestock, and habitat destruction due to the expansion of herding and ranching. Snow leopards are present in the mountains of Central Asia and the Indian Subcontinent. They inhabit an elevation of around 18,000 feet in the summer and 6,000 feet in the winter. The name suggests snow leopards are closely related to le...
