What else can I help you with?
Is igneous harder than sedimentary rocks?
Not necessarily. The hardness of a rock depends on its mineral composition and how it formed, rather than the type of rock it is. Some igneous rocks are harder than sedimentary rocks, while others may be softer. It varies depending on the specific rock type within each category.
More often than metamorphic or igneous rocks sedimentary rocks have what?
Sedimentary rocks have numerous fossils
What wears away more easily sedimentary rocks or igneous rocks?
Sedimentary rocks generally wear away more easily than igneous rocks due to their composition and structure. They are often made up of softer minerals and have a layered, less cohesive structure, making them more susceptible to erosion and weathering. In contrast, igneous rocks, formed from cooled magma or lava, tend to be denser and harder, providing them with greater resistance to wear. Thus, sedimentary rocks typically erode at a faster rate than igneous rocks.
How does sedimentary rock form to metamorphic rock?
Shale (a metamorphic rock) goes through heat and pressure than it turns into slate (a sedimentary rock)
ARE Fossils always found in igneous rocks?
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.
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.

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.
What are the three types of rock and their formation?
there are 4 bill bob and jerry and the one in abi's head she likes to call a brain Igneous, Sedimentary, and Metamorphic.
How hard are sedimentary rocks?
harder than metamorphic
Are sedimentary rocks softer than igneous rocks?
yes because it is sedimentry isnt it ]
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 :)
