Sedimentary rocks form through the accumulation and lithification (compaction and cementation) of sediments such as sand, mud, and organic materials. These sediments are typically deposited in layers by water, wind, or ice over long periods of time. Over time, the sediments become compacted and cemented together to form solid rock.
What else can I help you with?
Why sedimentary rocks could not have been the first rocks on earth?
Sedimentary rocks form from the accumulation of sediment such as sand, silt, or clay. For sedimentary rocks to form, there must be pre-existing rocks that weather and erode to produce sediment. Therefore, sedimentary rocks could not have been the first rocks on Earth as they require the presence of older rocks to form.
Can metamorphic rocks form form igneous but not from sedimentary rocks?
Metamorphic rocks can form from both igneous and sedimentary rocks through the process of heat and pressure, but they are more commonly associated with forming from existing metamorphic or sedimentary rocks. Igneous rocks can indirectly contribute to the formation of metamorphic rocks by heating up and altering surrounding rocks, leading to the formation of new metamorphic rocks.
All of the following are ways in which sedimentary rocks form execpt?
lava cooling
When rocks undergo weathering they become what type of rock?
When rocks undergo weathering, they can form sedimentary rocks. Weathering breaks down rocks into smaller sediments, which then get compacted and cemented together to form sedimentary rocks.
What types of rocks initially form from deposition?
Sedimentary rocks form from the deposition and compaction of sediment such as sand, silt, and clay. These rocks include sandstone, shale, and limestone.
What else can sedimentary rocks form from?
All rocks can form from sedimentary because the rock cycle is endless.
What type of rocks weather and erode to form sedimentary rocks?
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
Can Metamorphic rocks can form from igneous but not from sedimentary rocks.?
Metamorphic rocks can form from both igneous and sedimentary rocks
Can metamorphic rocks can form from igneous but not from sedimentary rocks?
Metamorphic rocks can form from both igneous and sedimentary rocks
What do sedimentary rocks form from?
Sedimentary rocks form from a few different things. Sedimentary rocks form from sediment is deposited out of air, ice, wind and gravity.
Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.
How are clastic sedimentary rocks different from organic sedimentary rocks?
they form
What type of rocks can contain fossils on them?
Sedimentary rocks. and metamorphic rocks made form sedimentary rocks.
What is the or-gin of sedimentary rocks?
weathering of preexisting rocks form clastic sedimentary rocks, Oversaturated water basins form chemical sedimentary rocks after the water evaporates and dead sea organisms settle at the bottom forming biochemical sedimentary rocks.
Rocks that form when sediment cements and hardens together and hardens?
Sedimentary rocks.
What rocks form from the sediments of the other rocks?
Sedimentary rocks.
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
