They are generally harder because of their interlocking crystalline structure and mineral composition.

Are sedimentary rocks are harder than igneous rocks?

No, igneous rocks are harder than sedimentary rocks on average.


Which rock would be harder to break with a hammer a sedimentary rock or an igneous rock?

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.


More often than metamorphic or igneous rocks sedimentary rocks have what?

Sedimentary rocks have numerous fossils


Which is older igneous or sedimentary?

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.

Can slate be worn away easily?

As slate is a metamorphic rock, it can't be worn easily. I t would be harder to wear than igneous or sedimentary rocks.


What do sedimentary rocks have more often than metamorphic or igneous 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.


Why are sedimentary rocks softer than igneous rock?

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.


Which types of rocks are not 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 :)


Are igneous rocks less porous than sedimentary rocks?

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.
