If other layers of rock, dirt, dust, and sand are put on top of the igneous rock and the layers are compressed by their own weight, they become a single, unified layer of sedimentary rock.
Simple Version:
1. Igneous rock
2. More rocks are put on the igneous rock.
3. The rock on top push down and squeeze the all of the layers into one layer.
Igneous rocks are a "finished product". They do not become sedimentary rock - though sedimentary rocks, with heat and pressure can become metamorphic rocks.
Sedimentary and Igneous rocks are not metamorphic rocks. Metamorphic rocks however are igneous or sedimentary rocks that have undertaken metamorphism (In extreme heat and/or pressure the minerals are forced to recrystalize) and become metamorphic rocks. If the heat/pressure causes the rock to melt into liquid rock than it is no longer metamorphi, it is igneous. Hope this helps :)
No. Volcanic rocks are igneous (although not all igneous rocks are volcanic). Sedimentary rocks are made of sediment naturally cemented together. However, volcanic (or extrusive igneous) rocks can be eroded into sediment, which can be cemented, compacted, or otherwise become sedimentary rock such as sandstone or conglomerate. It is then not considered igneous.
sedimentary rocks
Both sedimentary and igneous
A sedimentary rock is formed when an igneous rock is subjected to weathering, erosion, compaction, and cementation!
igneous, sedimentary, metamorphic
Igneous rocks can become sedimentary rocks through the process of weathering and erosion, which breaks down the igneous rocks into small particles. These particles are then transported and deposited, forming layers of sediment. Over time, the pressure and compaction from the overlying layers can cement the sediment particles together, creating a sedimentary rock.
Two of the most common fates of igneous rocks are to become sediment (and later sedimentary rocks) or to become metamorphic rocks.
Sedimentary rocks can be eroded into sediments and form sedimentary rocks again, they can melt and become igneous rocks, and they can undergo extreme heat and pressure and become metamorphic rocks.
No, igneous rocks are harder than sedimentary rocks on average.
Yes, after erosion and deposition.
