The layers that you may see in certain sedimentary rocks are from different depositions of sediment. A tide could deposit a sediment layer, as could seasonal flooding or any number of other sources of sediment. A few years of heavy rains would likely leave dirtier and darker deposits. Any violent change in the area ( earthquakes, volcanoes, etc. ) might completely change the nature and color of the deposits on a short term or permanent basis. Biologics ( anything from bacteria to dinosaurs ) might have a period of unrestrained growth, affecting the type and shades of the layers. Analysis of the layers can provide a geologic history and source of the rock.
What else can I help you with?
Fossils are found only in .?
Sedimentary rocks
What type of rock are mostly found in mountains?
volcanic mountains are mostly associated with igneous rocks and sedimentary rocks at their slopes can be found due to weathering,but mountains such as fold mountains can contain igneous rocks,metarmophic ro cks and even sedimentary rocks at their slopes
Gravel sandstone and conglomerate are all types of?
Gravel, sandstone, and conglomerate are all types of sedimentary rocks.
What is the class that includes sedimentary rocks which are deposited from a solution made by organic processes?
Sedimentary rocks are broken into two classes: clasticand chemical. Clastic sedimentary rocks are composed of rock particles, and chemical sedimentary rocks are composed of precipitation of minerals in solution.
Why are fossils most likely to be found in sedimentary rock samples?
Most fossils are found in sedimentary rock, because igneous and metamorphic rock undergo great heat and pressure when forming, where as sedimentary rocks undergo much less pressure and heat to form, better preserving the fossil
What are rocks with stripes called?
Rocks with stripes are known as banded rocks or striped rocks. These stripes are often caused by the layering of different minerals or the presence of alternating bands of different mineral compositions within the rock.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
What type of rocks has stripes or layers in it?
Rocks that have stripes or layers are typically sedimentary rocks. These layers, known as strata, are formed by the accumulation of sediment over time, which can include particles from other rocks, minerals, and organic matter. Common examples of layered sedimentary rocks include sandstone, limestone, and shale. The distinct layers can reflect changes in environmental conditions, such as shifts in water levels or sediment supply.
What rock has stripes or layers in it?
Sedimentary rocks like sandstone or limestone often have visible layers or stripes called strata. These layers form over time as sediment is deposited and compacted, creating distinct bands of different colors or textures.
What has the author Sam Boggs written?
Sam Boggs has written: 'Petrology of sedimentary rocks' -- subject(s): Sedimentary Rocks 'Petrology of sedimentary rocks' -- subject(s): Rocks, Sedimentary, Sedimentary Rocks
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.
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
What are three types of rocks?
igneous, sedimentary, metamorphic
What type of rocks can contain fossils on them?
Sedimentary rocks. and metamorphic rocks made form sedimentary rocks.
Are sedimentary rocks classified tofoliated sedimentary rocks?
No, sedimentary rocks are not classified as foliated. Foliation is a textural feature found in certain types of metamorphic rocks where minerals are aligned in layers or bands due to pressure and heat. Sedimentary rocks are formed by the accumulation and cementation of sediments and do not exhibit foliation.
How are clastic sedimentary rocks different from organic sedimentary rocks?
they form
What class of sedimentary rocks is made of fragments of rocks mineral and shells?
== == Clastic sedimentary rocks.
