Igneous rocks are made from magma. Magma is made of melted rocks. (When it is underground it is called magma, when it erupts on the surface of the earth, it is called lava. It's the same material though.) When magma/lava cools, it forms igneous rocks. There are many types of igneous rocks and the specific type of igneous rock can vary according to which minerals are present in the melted rock, how fast it cools, and the presence of things like water.
Sedimentary rocks are made out of tiny pieces of debris. This can include tiny rocks, sand, clay, silt, and organic material. (Organic materials can vary from rotted leaves to tiny, shelled ocean creatures, or many other types of organic material.) These bits of material collect in an area, then through compaction and cementation, they stick together to form sedimentary rocks.
Sedimentary rocks can also be formed when minerals are dissolved in water and are then resolidified. This type of sedimentary rock is called a chemical sedimentary rock. Oolitic limestone is a good example of this type of sedimentary rock.
What else can I help you with?
Are sedimentary rocks are harder than igneous rocks?
No, igneous rocks are harder than sedimentary rocks on average.
More often than metamorphic or igneous rocks sedimentary rocks have what?
Sedimentary rocks have numerous fossils
Is MT vesuvius made of sedimentary rocks?
No Igneous rocks!
Are pebbles igneous rocks?
No, pebbles are not necessarily igneous rocks by default. Pebbles can be formed from a variety of rock types, including igneous, sedimentary, and metamorphic rocks, depending on the geological processes that created them.
What type of rock is made from weathering and erosion?
Sedimentary rock is formed when igneous rocks weather to sediments, then the sediments compact to sedimentary rock. When Igneous rocks are subjected to heat and pressure but do not melt, they become metamorphic rock. When igneous rocks are melted they make other igneous rocks.
How are igneous and sedimentary alike?
Both are composed of minerals. Some sedimentary rocks contain pieces of igneous rocks.
What are three types of rocks?
igneous, sedimentary, metamorphic
Are sedimentary rocks are harder than igneous rocks?
No, igneous rocks are harder than sedimentary rocks on average.
Can metamorphic rocks can form from igneous but not from sedimentary rocks?
Metamorphic rocks can form from both igneous and sedimentary rocks
Can Metamorphic rocks can form from igneous but not from sedimentary rocks.?
Metamorphic rocks can form from both igneous and sedimentary rocks
What are 3 major rock types?
Igneous Rocks,Sedimentary Rocks,Metamorphic Rocks.
What is the name of all three rocks sedimentary igneous and?
Sedimentary, igneous and metamorphic.
How are metamorphic rocks igneous rock and sedimentary rocks different?
Metamorphic rocks originate as igneous and sedimentary rocks, but have been changed by heat and pressure.
What are the three types of rocks involved in the rock cycle?
The three types of rocks involved in the rock cycle are igneous rocks, sedimentary rocks, and metamorphic rocks. Igneous rocks form from the solidification of molten magma, sedimentary rocks form from the deposition and lithification of sediments, and metamorphic rocks form from pre-existing rocks that are subjected to high heat and pressure.
What are some examples of the three rock types?

How the igneous rocks change?
Igneous rocks change to Metamorphic rocks through heat and pressure. Igneous rocks change to sedimentary rocks through weathering and erosion until the igneous rock is sediments. The sediments then compact to form sedimentary rocks.
Which rocks would be formed above the surface of the earth?
Extrusive igneous rocks, some sedimentary rocks
