Limestone is a sedimentary rock made up of calcite (CaCO3) as its main mineral. Some limestones were formed by chemical deposition and others by the accumulation of shells from minute sea creatures. Many invertebrate animals (animals with no backbones) take calcite from sea water to construct their shells. When they die the shells fall to the sea bed. Areas where there is little deposition of mud or sand will be ideal for the formation of limestone. One type of limestone which is very pure is called chalk, but most other limestones contain variable amounts of mud or sand or other material.

What of the following is not an instructive igneous body?

An instructive igneous body typically refers to geological formations that provide insights into the processes of igneous rock formation. Common examples include plutons, sills, and dikes. However, a body like a lava flow, which is extrusive rather than intrusive, is not considered an instructive igneous body in the same context. Therefore, lava flows would be the correct answer.


Why can instructive igneous rocks be left behind when surrounding rocks are worn away?

Instructive igneous rocks, also known as intrusive igneous rocks, form from magma that cools and solidifies beneath the Earth's surface. Because they are typically denser and more resistant to erosion than surrounding sedimentary or volcanic rocks, they can remain intact even as those surrounding materials are worn away. Over time, processes like weathering and erosion can remove the softer rocks, revealing the more durable instructive igneous formations, which often appear as hills or mountains in the landscape.
