Explain the Characteristics of the Igneous Rocks.
Answers
there are many characteristics of Igneous rocks such as -
1. These rocks are hard and compact.
2. These rocks do not occur in
distinct beds or strata.
3. These rocks do not have remains
of animals or plants.
4. These rocks do not allow water to
percolate.
Here are your characteristics of igneous rocks -----------
♦Since igneous rocks are formed due to the cooling and solidification of the magma, these rocks are hard and resistant to erosion.
♦Water seeps in only through cracks and joints in the rocks. Thus these rocks are mostly not affected by chemical weathering.
♦Igneous rocks are also called primary rocks as other rocks are basically formed out of igneous rocks.
♦These rocks are usually fine grained with smooth texture or may have large crystals with coarse texture.
♦Since these rocks are formed due to the cooling and solidification of the magma (lava), fossils are not found in these rocks.
♦Igneous rocks can be further classified into extrusive igneous rocks or intrusive igneous rocks.
