What else can I help you with?
Are magma and lava sedimentary rocks?
No. Magma and lava are molten rock. When the cool they form igneous rock.
How does sedimentary rock turn to lava?
Sedimentary rock does not directly turn into lava. Instead, when sedimentary rock is subjected to extreme heat and pressure, it can undergo metamorphism, potentially transforming into metamorphic rock. If this metamorphic rock is further subjected to even higher temperatures, it can melt and become magma. When magma erupts to the surface, it is called lava.
What is the difference between igneous and sedimentary rocks?
Igneous rock is formed from the solidification of magma or lava. Sedimentary rock is formed from the lithification of sediments, generally.
Can sizes of crystals in sedimentary rock tell us how quickly the lava or magma cooled that formed the rock?
Yes it can.
How would igneous rock be on a layer of sedimentary rock?
The igneous rock could have been erupted as lava on the surface, or intruded into the sedimentary rock layers as magma underneath the surface (a sill).
Is sandstone an igneous rock?
No. Sandstone is a sedimentary rock, composed of cemented grains of sand-sized sediment particles. Igneous rock is formed from the cooling of magma or lava.
How does sedimentary rock turn into lava?
Sedimentary rock can transform into lava through a process called melting. When sedimentary rock is subjected to extreme heat and pressure, typically deep within the Earth's crust or mantle, it can melt and become magma. If this magma rises to the surface and erupts, it is expelled as lava. However, this transformation is less direct than the metamorphic processes; sedimentary rocks typically undergo significant changes before melting occurs.
Why are there no fossils in a intrusion?
If you mean an intrusion via magma/lava, then fossils would not exist due to the fact that most fossils are found in SEDIMENTARY rock, not IGNEOUS (magma/lava rocks).
What type of rock contains lava or magma?
The type of rock that contains lava or magma is an igneous rock.
How are lava and magma and igneous rock related?
Magma is molten rock under ground whereas molten rock that flows out of the ground is lava and igneous rock is solid when the lava or magma hardens.
A rock made from cooled magma or lava?
Igneous rock is formed from solidified and cooled magma or lava.
What are lava and magma made of?
Lava and magma are composed of molten rock.
