What changes are involved when mud from a lake bottom turns into a sedimentary rock then into a metamorphic rock?

The sediments on the lake bottom undergo lithification and become sedimentary rock. Further compaction, pressure, and heat turn it into metamorphic rock.

What type of rock is found in layers and forms when bits of settles to the bottom of rivers lakes and oceans igneous metamorphic or sedimentary?
Sedimentary
How do metamorphic rocks form differently from sedimentary rocks?
Metamorphic rock is formed under high temperature and pressures which are not present on the surface. The erosion processes at the surface are low temperature and pressure, and aqueous, which more closely match the formation processes of sedimentary rock. Thus one can see the process of erosion as the undoing of the formative process. This better matches sedimentary than metamorphic.
What type of rock is formed when soil settles at the bottom of ponds and rivers?
Sedimentary rock.
From the rock cycle describe the changes that an igneous rock could undergo?
As describe by the rock cycle, an igneous rock can undergo three types of changes. First, it can be weathered and then compacted into a sedimentary rock, such as obsidian weathered into shale. Next, an igneous rock can, through heat and pressure, be changed into a metamorphic rock. Granite, which is an igneous rock, can be metamorphosed into gneiss. Finally, an igneous rock can be be melted and then cooled into another igneous rock. For example granite, which results from relatively slow cooled magma in the Earth's crust, can be re-melted and rapidly cooled, turning it into obsidian.
How is weathering related to the formation of sedimentary rocks?
Weathering is the breaking down of existing rock into smaller pieces that are transported by erosion to a place of deposition, which can lead to compaction and cementation--two processes necessary in the formation of sedimentary rock.

Sedimentary
What part of the sedimentary of rock is the oldest?
Protolith is a term used to describe the parent rock of a metamorphic rock. Conglomerate is a sedimentary rock that can be composed of clasts of sedimentary, igneous, or metamorphic rocks, or any number of combinations of all.
How a metamorphic rock could turn into a sedimentary rock and then back into a metamorphic rock?
By exposure to heat and/or pressure through depth of burial, directed pressure, or proximity to a magma source. Existing minerals can recrystallize, non-hydrous minerals can replace hydrous minerals, new minerals can be formed from the introduction of new ions from heated solutions, and minerals can become flattened and aligned in parallel layers.
Where are the three types of rocks found?
Sedimentary rocks are found generally at the bottom of an ocean as this is where eroded material falls. Igneous rocks are found near volcanoes as they are molten rock. Metamorphic rock can be found anywhere, as it is formed in the ground and slowly comes up to the surface (but it is made of igneous or sedimentary rocks.)
How do metamorphic rocks form differently from sedimentary rocks?
Metamorphic rock is formed under high temperature and pressures which are not present on the surface. The erosion processes at the surface are low temperature and pressure, and aqueous, which more closely match the formation processes of sedimentary rock. Thus one can see the process of erosion as the undoing of the formative process. This better matches sedimentary than metamorphic.
Where would you most likely find a sedimentary rock such as sandstone?
Sandstone---as exposed rock on the surface of the Earth in tectonically lifted former beach or deltaic deposits. Sedimentary rock---the majority of rock units on the surface of the Earth are sedimentary in nature.The keyword is 'surface'.
What process must a sedimentary rock go through to become one?
A sedimentary rock gets buried within the crust due to the movement of the plate tectonics; gets baked and becomes a metamorphic rock OR gets melted and solidifies to become an igneous rock. When the rocks (either metamorphic or igneous or both) are exposed, weathering and erosion occurs and the rock sediments are transported where they deposit at the bottom of a water body and get compacted (by the weight of the layers of sediments above) and cemented (by the minerals dissolved in the water) to become a sedimentary rock.
Which metamorphic rock is formed from marble?
Limestone is typically the product of accumulated decomposed marine life as it settles to the bottom of a body of water.This sedimentary rock, laid down in earlier geological ages, is the starting material for marble.When limestone is exposed to geological pressure and heat, it changes (metamorphosizes) into marble.The metamorphic stone known as marble is highly alkaline, like limestone, but is far less porous (permeable), and much denser and harder.Marble quarries are areas of the earth that were once sea bottoms, then were exposed, through tectonic plate activity, to great heat and pressure.
Describe the process by which metamorphic rock can become sedimentary rock?
First the metamorphic schist would have to become exposed through means of uplift and erosion. Subjected to weathering, rock particles will become transported by wind and water, becoming smaller and smaller until they fit the definition of sand grain size. Rivers and streams will eventually transport the tiny particles to the continental shelf where they will sink to the bottom and be covered by additional layers of sand. Because of the weight of overlying layers, the sandgrains will undergo a process known as lithification, where excess water is squeezed out and a cementing mineral solution will bind the sand grains together. At this point it can be called sandstone.
Can a moon rock become sedimentary rocks?
no because sedimentary rocks are made at the bottom of oceans
What type of rock is formed when soil settles at the bottom of ponds and rivers?
Sedimentary rock.
Can sedimentary rocks be formed at the bottom of lakes?
Yes they can. Their facies is called "lacustrine".
