no slate is an igneous rock
No, slate is a metamorphic rock that is formed by shale
The answer is Shale. Slate is a metamorphic rock derived from shale, granite is an intrusive igneous rock, and pumice is a vesicular extrusive igneous rock.
Slate and gneiss are examples of metamorphic rock.
Igneous
An igneous rock is cooled magma. So first it would have to melt. From there it could become any igneous rock depending on the environment.
the cycle of the rock is that firstly it is igneous rock which is formed under a volcano, the it is sedimentary rock e.g. limestone then that transforms into metamorphic rock which is marble or slate.
The metamorphic rock, slate, is considered foliated.
igneous
No. Granite is an intrusive igneous rock, formed from the solidification of magma underground. Slate is a low grade metamorphic rock formed from heat and pressure applied to deposits of shale, a sedimentary rock.
As slate is a metamorphic rock, it can't be worn easily. I t would be harder to wear than igneous or sedimentary rocks.
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.
