Which rock is also called as primary rock?
Igneous rocks– formed by the cooling and solidification of magma (molten rocks). It begins the rock cycle. So it is known as primary rocks.
Why igneous rocks are also called primary rocks or mother rocks?
Igneous rock is popularly known as primary rocks or mother rocks because all other rocks are directly or indirectly formed from Lava and Magma. Lava and Magma are the materials which are found under the earth surface. When this magma reaches the earth surfaces it is called lava.
Why are sedimentary rocks called secondary rocks?
Sedimentary rocks are called secondary because they are often the result of the accumulation of small pieces broken off of pre-existing rocks. There are three main types of sedimentary rocks: Clastic: your basic sedimentary rock.
