Why does the law of superposition apply mostly to sedimentary rock?
The law of superposition applies mostly to sedimentary rocks because the law of superposition states that each layer is older than the one above it and younger than the one below it. Sedimentary rock is formed mostly by sediments which have been laid down over time, and then lithified into rock. Igneous and metamorphic rocks have different processes of formation which which are more to do with heat and pressure, and less to do with sequential deposition.
What 2 things are applied to igneous or sedimentary rocks that make metamorphic rocks form?
Heat and pressure!!
What geologic law is applied if an igneous intrusion is observed through a layer of sedimentary rock?
law of crosscutting relationships.
Is tuff igneous sedimentary or metamorphic?
igneous (extrusive)
Is gypsum igneous metamorphic or sedimentary?
sedimentary
How are metamorphic and sedimentary igneous rocks formed?
Igneous- Formed from hot molten magmaSedimentary- formed from sediments piling up creating layersMetamorphic- Formed when intense heat AND pressure are applied to an igneous or sedimentary rock.
How do igneous rocks form into metamorphic and sedimentary rocks?
Igneous-sedimentary weathering/erosion Igneous-Metamorphic high pressure and heat

What processes can transform igneous rocks into sedimentary rock?
In order for an igneous rock to be changed to a sedimentary rock the rock must be weathered down into, well, some form of sediment (sand, gravel, ect.) and then have pressure applied to it to become a sedimentary rock.
What are crystals igneous sedimentary or metamorphic?
its igneous and sedimentary and metamorphic

What geologic law is applied if an igneous intrusion is observed through a layer of sedimentary rock?
law of crosscutting relationships.
Is graphite igneous sedimentary or metamorphic?
Graphite is a mineral, not a rock that is classified as metamorphic, igneous or sedimentary.
Is made of sediments an igneous rock characteristics?
No, rocks made of sediments are called sedimentary rocks. Igneous rock comes from volcanic activity -- lava and the like.
What is the name of all three rocks sedimentary igneous and?
Sedimentary, igneous and metamorphic.
Is mudstone igneous or sedimentary?
Mudstone is sedimentary
What makes a sedimentary or igneous rock form to a metamorphic rock?
heat and pressure is applied to the rock and it becomes a metamorphic rock.
