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.

How could you explain the presence of an igneous rock in a bed of sedimentary rock?
An igneous rock can be found within a bed of sedimentary rock due to geological processes such as intrusions or volcanic activity. These igneous rocks might have been forced into the sedimentary layers during a period of geological upheaval, creating a mixed rock formation.
What can an igneous turn into during the rock cycle?
During rock cycle an igneous rock could turn into any of the three types of rock. It could undergo weathering and form sediments which results to sedimentary rocks, it could also under intense temperature and pressure without melting to form metamorphic rock and can also become part of molten magma to form igneous rock again.
What two groups of rocks that form all 3 kinds of rocks?
In reality, every rock on Earth could be formed of ingredients from any of the three rock types: sedimentary, igneous, metamorphic. This is referred to as the rock cycle, the continuous, billions of years old process of rock recycling.As for the direct transformation of one rock type into another due to heat and pressure, only metamorphic rock can be created this way. The metamorphism can occur to existing sedimentary, igneous, and metamorphic rock.Igneous rock can be eroded into sediments, Ultimately becoming Sedimentary rock. And it can also be metamorphosed by heat and pressure, becoming a Metamorphic Rock before being melted into Igneous. Sedimentary Rock can also be eroded into sediments, Ultimately becoming another Sedimentary rock. And it can also be metamorphosed by heat and pressure, becoming a Metamorphic Rock before being melted into Igneous. Metamorphic Rock can be eroded into sediments, Ultimately becoming Sedimentary rock. And it can also be metamorphosed farther by heat and pressure, becoming another type of Metamorphic Rock in the line before being melted into Igneous.
What type of rocks from when magma erupts from undersea volcano?
All three rock types could be formed in areas under the seas. Two types of rock are most likely to form on the seafloor, however. Sedimentary rock is formed on the seafloor where accumulations of sediments undergo lithification processes. Extrusive igneous rock can form on the seafloor when lava erupts on its surface.
What is the name of black mineral in igneous and metamorphic rocks?
The black in igneous and metamorphic rocks could be any of numerous black minerals. Two that are commonly found are biotite mica and hornblende.

How can a rock be made of igneous and sedimentary components at the same time?
Different source areas came together in one place. Still considered sedimentary, because it's composed of sediments. Doesn't matter what the composition is, could be metamorphic in there too.
When igneous rocks are exposed on Earth's surface and undergo weathering they eventually become which rock?
When igneous rocks are exposed on Earth's surface and undergo weathering, they break down into smaller particles and eventually become sedimentary rocks through the process of erosion, transportation, deposition, and lithification.
Can you explain the presence of the ghostly figure in the photo?
The presence of the ghostly figure in the photo is unexplained and mysterious. Some believe it could be a trick of light or a reflection, while others think it may be a supernatural phenomenon.
How does a igneous rock turn into an sedimentary rock?
Igneous rock, when exposed, will weather into smaller particles by mechanical and chemical means. Eventually the particles will be eroded and be transported by wind, water, ice, and gravity and eventually be deposited along with other sediments in a low lying area; could be the bottom of a sea, ocean or lake. As further and further sedimentation and accretion occur, the weight of overlying sediments compacts the particles, squeezing out air and water. Minerals then can bridge the gaps between particles, cementing them together into sedimentary rock.
Could igneous granite float?
No, but pumice can.
What color is a igneous rock?
It could be Granite.
From the rock cycle describe the changes that a sedimentary rock could undergo?
A sedimentary rock could undergo further compaction and cementation to become a metamorphic rock due to increased heat and pressure. It could also melt and solidify into an igneous rock through volcanic activity. If exposed to erosion, it could break down into sediments and form new sedimentary rocks through deposition and lithification.
Are igneous rocks big or small?
An igneous rock could be of any size, from microscopic to miles in diameter.
Can a igneous rock become another igneous rock?
Yes
What processes occur that change a sedimentary rock into an igneous rock?
Sedimentary rock can be turned into lave or magma by contact with either of the substances or exposure to extreme heat. When the lava or magma cools, it becomes igneous rock.Students who are using wiki.answers.com could be advised that copying word for word is plagerizm.
