Slate is so hard because it came from shale that is put under pressure with high temperature. The clay composition of shale converts to mica, making it hard.

Is slate harder than shale?

Yes, slate is harder than shale. Slate is a fine-grained, foliated metamorphic rock that has undergone more intense heat and pressure than shale, a fine-grained sedimentary rock. As a result, slate is more durable and resistant to erosion compared to shale.


What is a metamorphic rock formed from a shale?

Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.


What is similarities between shale and slate?

Slate and shale have the same make-up. Slate is formed from sedimentary shale by pressure and heat. Wet shale has the same smell that wet slate has.


What rock is slate but in the past it was shale?

Shale is a sedimentaory rock, while Slate is a metamorphic rock. Generally the shale is metamorphosed into slate.


Why is slate denser is denser than shale?

Slate is denser than shale because it has undergone more pressure and heat during the metamorphic process, causing it to become more compacted and less porous. This leads to a higher density in slate compared to the original sedimentary rock shale.


Was slate once shale?

Yes, slate was once shale. Shale is a sedimentary rock formed from the compaction of mud and clay, while slate is a metamorphic rock that forms from the metamorphism of shale. The process of metamorphism involves heat and pressure, which transforms the shale into slate by aligning the minerals and creating a foliation (layering) within the rock.


Slate is a denser version of?

Slate is metamorphosed shale or mudstone.


Is slate a metamorphic rock which transforms from shale?

Slate is a metamorphic rock formed from the parent rock shale.


Why do you think slate might be denser than shale?

Slate is typically denser than shale because it undergoes more intense metamorphism, which compresses and realigns the minerals in the rock, resulting in a higher density. Shale, on the other hand, is a sedimentary rock that has undergone less alteration and compaction, leading to a lower density compared to slate.


Is a metamorpic rock formed from shale?

yes, it's slate. it goes from shale to slate to phyllite to mica schist.


What is metamorphic rock formed from shale?

Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.


What is the parent rock of slate?

The parent rock of slate is shale. Slate forms from the metamorphism of shale, which is a sedimentary rock composed of clay and silt-sized particles. The intense heat and pressure during metamorphism cause the clay minerals in shale to recrystallize into a dense, foliated structure characteristic of slate.
