Is sedimentary rock made from solidified lava?
Rock that is formed from volcanoes are igneous rocks. Sedimentary rocks are formed from other layers of grains that are heaving and over millions of years have enough weight squish the grains into a proper rock. This is why the newest rocks are found at the top of layers.
What features of sedimentary rocks are unlikely to be found in metamorphic rocks what features of metamorphic rocks do not occur in 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.
Are sedimentary rocks chemically weathered?
Sedimentary rocks can be both chemically and mechanically weathered.
Is sedimentary rocks formed the same way normal rocks are?
No, because a sedimentary rock is formed from pieces of other rocks.
Why do sedimentary rocks wear away faster than others?
Sedimentary rocks tend to erode easily compared to other types of rocks as the grains within them are farther apart than the "grains" in, let's say, igneous rocks. As a result of this, the "grains" can be easily crumble. An example of this is sand.
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.
Rocks that erodes to expose layering is?
Sedimentary rocks, such as sandstone or shale, erode to expose layering due to the distinct horizontal beds created during the deposition process. The layering, or bedding, in sedimentary rocks forms as sediments settle and accumulate over time, preserving a record of the Earth's past environments and processes.
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.
What happens if water flows across rocks steadily for years?
The rocks erode and cause sedimentary rocks, such as shale. The river will most likely cut across the rock.
Why do rocks erode at different rates?
Rocks erode at different rates depending on factors such as composition, hardness, and environmental conditions. Soft rocks erode more quickly than hard rocks because they are more easily weathered by elements like wind and water. Additionally, the presence of minerals in the rock can affect its susceptibility to erosion.
Can salt erode rocks faster?
Yes, because the ion chloride (Cl-) is corrosive.
Which type of rock will be changed most by a flood?
Sedimentary rocks, such as mudstone or sandstone, are most likely to be changed by a flood due to their composition and porosity. Floodwaters can break down and erode sedimentary rocks more easily compared to igneous or metamorphic rocks.
How do igneous rocks from into a sedimentary rock?
Igneous rocks can weather and erode over time, breaking down into smaller sediment particles. These particles can then be transported by water, wind, or ice, and eventually settle and accumulate in layers. Through compaction and cementation, these layers of sediment can harden into sedimentary rocks.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
As rocks erode from Earth's surface the process they are replaced by is?
The process by which rocks are replaced as they erode from Earth's surface is called deposition. Deposition occurs when eroded rocks and sediments are transported to a new location and settle out of the transporting medium, such as wind or water, to form new layers of sedimentary rock.
What is the process whereby softer sedimentary rocks erode more quickly than harder rock shaping the surface of the landscape?
Weathering and erosion.
