Sedimentary rock is formed from different sediments (rock, dirt, bits of each, etc.), over time, pushed and pressured into a solid, a rock. Igneous rocks are formed by the cooling of lava, which is rock anyway, only melted.
Example of Sedimentary- sandstone
Example of Igneous- obsidian

∙ 13y agoSediment is deposited from weathering and erosion onto river banks most likely. The sediment stays like that until more and more sediment is deposited. Then it is compacted ("crushed", you could say) and cemented (cemented is where water and other chemicals in the ground mix with each other, forming a sticky paste which is mixed with the sediment) and the result is a striped rock.

How does igneous rock change to sedimentary?
Sedimentary rock melts, then it cools to form Igneous rock. Hoped this helped. :)
How does a sedimentary rock contain pieces of igneous rocks?
Igneous rock pieces can stick together through cementation to form sedimentary rocks.
What kind of rock does not require heat to form?
Sedimentary rock. Because when weathering and erosion occurs to igneous rock, the igneous become sediments and the sediments condense and cool, forming sedimentary rock. Therefore, sedimentary rock doesn't need heat to form.
True or false sedimentary rock can be formed from changes in igneous rock but idneous rock cannot be formed changes in the sedimentary rock?
False Sedimetary rocks can be formed from changes in igneous rock, and igneous rock can be from changes in sedimentary rock.
What rock can be broken into fragments that may later form sedimentary rocks?
Any rock (igneous, sedimentary or metamorphic) may be broken into fragments that may later be formed into sedimentary rock.
What is granite in sedimentary form?
No, it's not a sedimentary rock, it is an igneous rock. :)
How does igneous rock change to sedimentary?
Sedimentary rock melts, then it cools to form Igneous rock. Hoped this helped. :)
What do Volcanic eruptions form igneous rock sedimentary rock or metamorphic rock?
Igneous rocks
When magma cools and hardens does it form igneous rock sedimentary rock or metamorphic rock?
igneous rock.
Why do rock fossils form in sedimentary rock and not in igneous rock?
because sedimentary rocks are on the top layer, while igneous rocks are were the magma is
Does sedimentary rock form igneous rock?
Yes it can form an igneous rocks as because of pressure it may melt and form into igneous rocks.
What type of rock can only be formed from sedimentary rock or igneous rock?
Metamorphic rock can form from igneous and sedimentary rock. It can also form from previously metamorphosed rock into a higher grade metamorphic rock.
Where can strata can be found sedimentary rock or igneous rock?
Sedimentary Rock. Strata is layers of sedimentary rock that form from the deposition of sediment.
What kind rocks can the igneous rock form?
sedimentary
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)
How does a sedimentary rock contain pieces of igneous rocks?
Igneous rock pieces can stick together through cementation to form sedimentary rocks.
What kind of rock does Igneous rock eventually form?
Sedimentary or metamorphic.
