Molten rock (igneous rock) may be worn down (weather and erosion), turning into pebbles, then due to things such as floods, they can get washed down into a lake where the water is calm. Things such as clay and sand settle down too, as well as other rocks. Over many years (we're talking thousands, millions of years here) all of those things get compressed and eventually the pressure is so great that it forms one big bit of rock. That's why in sedimentary rock you see all the layers, they are all the layers of things like sand, clay and rocks all pressed together. I think that's how a lot of sedimentary rocks are made. Metamorphic rock may also be turned into sedimentary this way.

Can pebbles change into igneous metamorphic and sedimentary rocks?
No. It's too late.Unless it gets eroded itself and eventually forms layers of sediment which may then get turned into rock.
Is obsidan a sedimentary rock?
No. It is an igneous rock, meaning it cooled from molten rock. Specifically, obsidian is volcanic.
What type of rock can become sedimentary?
Any type of rock, igneous, metamorphic or sedimentary, can become eroded and re-deposited and cemented together to become a new sedimentary rock.
Why are few sedimentary rock found deep inside the earth?
any rock can become a sedimentary rock.
How can ingneous rock disturb sedimentary rock layers?
Molten Rock from with in earth can force its way up through the layers above it cooling and forming igneous rock.
Can sedimentary rock be changed into igneous rock?
If it is forced back into the molten layers of the Earth, then yes, it will become igneous rock.
What rock or rocks could come just after quartzite in the rock cycle?
Quartzite could either become molten and then solidify into an igneous rock, or weather into particles of sediment that become a sedimentary rock.
When granite melts and then solidifies it become?
It would become an igneous rock. What type of igneous rock would depend on what it mixed with while molten, and if it solidified at or under the surface.
Are sedimentary rocks made when molten lava cools?
is a sedimentary rock created when lava hardens
The kind of rock that cooled from the molten state is?
The type of rock which cooled from the molten state is igneous rock. The other main types of rock are sedimentary and metamorphic.
What is igenous intrusion?
When molten rock breaks through sedimentary (compacted sand) rock
Can pebbles change into igneous metamorphic and sedimentary rocks?
No. It's too late.Unless it gets eroded itself and eventually forms layers of sediment which may then get turned into rock.
Is obsidan a sedimentary rock?
No. It is an igneous rock, meaning it cooled from molten rock. Specifically, obsidian is volcanic.
What are the two processes that result in a metamorphic rock?
For metamorphic rock to change into igneous rock, it must first melt. Once molten, if its liquid constituents cool and solidify, it has become an igneous rock. Metamorphic rock can become molten by exposure to heat and pressure from depth of burial and compression through tectonic plate subduction, or from close proximity to a magmatic heat source.The metamorphic rock could also become exposed to weathering, erosion, and subsequent deposition, compaction and cementation which would lead to the formation of sedimentary rock. Once again, the sedimentary rock could become molten by exposure to heat and pressure from depth of burial through tectonic plate subduction, or from close proximity to a magmatic heat source. Once molten, if its liquid constituents cool and solidify, it has become an igneous rock.Igneous or sedimentary rock
Which type of rock forms when sediments become pressed and cemented together?
When cemented together, clastic sedimentary rock.
Is it possible for a sedimentary rock to be changed to become a new sedimentary rock?
Yes it is possible for a sedimentary rock to be changed into a different sedimentary rock.
What type of rock can become sedimentary?
Any type of rock, igneous, metamorphic or sedimentary, can become eroded and re-deposited and cemented together to become a new sedimentary rock.
