They are generally harder because of their interlocking crystalline structure and mineral composition.
No, igneous rocks are harder than sedimentary rocks on average.
Sedimentary rocks have numerous fossils
Shale (a metamorphic rock) goes through heat and pressure than it turns into slate (a sedimentary rock)
No, fossils are typically found in sedimentary rocks rather than igneous rocks. Sedimentary rocks form from the accumulation and lithification of sediments, making them more likely to preserve fossils due to their layered nature. Igneous rocks, on the other hand, form from the cooling and solidification of molten rock and are less likely to contain fossils.
No, granite is harder than bauxite. Granite is a type of igneous rock that is known for its durability and hardness, while bauxite is a sedimentary rock that is softer in comparison.
No, igneous rocks are harder than sedimentary rocks on average.
You would normally think that an igneous rock would be harder to break. However, it completely depends on which igneous rock is being compared to which sedimentary rock, as their resistance to breakage is so varied. There are some igneous rocks (obsidian and pumice, for example) that would break much easier than some sedimentary rocks, such as chert or flint.
Sedimentary rocks have numerous fossils
Igneous rocks are typically older than sedimentary rocks. Igneous rocks form from the cooling and solidification of molten material (magma or lava), which usually happens before the formation of sedimentary rocks through processes like erosion, deposition, and compaction.
there are 4 bill bob and jerry and the one in abi's head she likes to call a brain Igneous, Sedimentary, and Metamorphic.
harder than metamorphic
yes because it is sedimentry isnt it ]
As slate is a metamorphic rock, it can't be worn easily. I t would be harder to wear than igneous or sedimentary rocks.
Sedimentary rocks often have visible layers or bedding, which are less common in metamorphic or igneous rocks. Sedimentary rocks also tend to contain fossils, as they are formed from the accumulation of sediments. Additionally, sedimentary rocks are more likely to be composed of minerals that are common in the Earth's crust.
It's because sedimentary rocks have big air spaces in them which makes them very porous, whereas igneous and metamorphic rocks are less porous, as the crystals are tightly packed.
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 :)
Generally, yes. Igneous rocks are typically less porous than sedimentary rocks because they form from molten magma that cools and solidifies quickly, leaving minimal space for pores to form. Sedimentary rocks, on the other hand, are often composed of loose grains or fragments that can create more pore spaces within the rock.
