How could you explain the presence of an igneous rock in a bed of sediments rock?
The sediment from which sedimentary rock is formed originally came from other rocks that weathered away. In some sedimentary rocks, especially breccia and conglomerate, some of those rock fragments can still be identified. If it does not appear to be part of the sediment, there are a few possible explanations depending on their relationship. If there is a layer of igneous rock between sedimentary layers then it could be from a volcanic eruption that occurred during the time of sedimentation, or a sill that intruded between layers after they formed. If the igneous rock appears to cut through the sedimentary rock then it most likely is an intrusion. If there is a piece of igneous rock that happens to be in an area where the local bedrock is sedimentary then it may have been transported there by glaciers.
Why are you most likely to only find fossils in sedimentary rocks?
Most fossils are found in sedimentary rock because it forms in layers so it is easier for the bones or shell of an organism to get trapped between the layers and be preserved. The other two types of rock, metamorphic and igneous, go through much heating and reforming so many remains are destoyed before minerals can preserve them.
Is igneous or sedimentary rock more likely to contain fossil?
sedimentary
What sedimentary rock is most likely to have a fossil?
Coquina is the sedimentary rock most likely to contain visible fossils.
The most common minerals in clastic sedimentary rocks are likely?
the most common minerals in clastic sedimentary rocks are likely
What is an unconformity between two sedimentary layers most likely produced by?
Erosion of the missing layers.
In what type of rock would you most likely find layers?
Sedimentary rock, most likely.
Is you put Heat And Pressure On Sandstone you get what?
As sandstone is a sedimentary rock formed from grains of sand over millions of years), applying heat and pressure is likely to pulverise the sandstone.
Sedimentary rocks that formed organically typically contain what?
Sedimentary rocks that formed organically typically contain calcite. Fossils are most likely to be found in sedimentary rocks.
You find a rock and notice it is formed from layers it is most likely to be which type of rock?
It is most likely to be sedimentary. However both Igneous and metamorphic rocks can manifest a layered structure so this feature is not diagnostic on its own.
What is the most important sedimentary rock feature?
rocky
Which sedimentary rock type is likely to be formed in the most offshore environment?
Limestone.
Which process most likely formed a layer of the sedimentary rock gypsum?
precipitation from seawater
Why is a sedimentary rock called stratified rock?
It most likely means that each layer of the stratificaton represents a time of flood, when a large layer of fresh silt was washed into the body of water, settling to the bottom over pre-existing layers.
Which sedimentary rock type most likely formed from ancient sand dunes?
Clastic rock
What type of rock are you most likely to find a fossil?
You are most likely to find them in sedimentary rock.
