How can rocks show that changes take place?
Rocks can show changes through processes like sedimentation, metamorphism, and weathering. The presence of different types of rocks, such as sedimentary, igneous, and metamorphic, can indicate past environmental conditions and overall geological change over time. Fossils found in rocks can also demonstrate biological changes that have occurred.
How are sedimentary rocks important to human knowledge?
Sedimentary rocks are composed of layers, and show how layers have built up over time. Hope this helps!
Which type of rock is likely to show ripple marks and fossils?
Sedimentary rocks show fossils, because of pre-existing life forms. They also show ripple marks due to weathering and erosion...
How can sedimentary rocks show earth history?
they have fossils and pieces of the environment from the past inside of them
Where can you find a sedimentary rock?
Examples of sedimentary rock include:BauxiteLimestoneDolostoneBrecciaConglomerateShaleMudstoneBituminous CoalSandstoneHaliteGypsumChalkCoquinaLateriteArkoseGraywackeClaystoneSiltstoneChertTypes include clastic (cemented sediment particles), non-clastic (chemical precipitates or evaporites), and organic (from organisms, e.g. coal). Some will further divide sedimentary rocks into another type called bioclastic, rocks formed from clasts of organic matter (like sea shells).
What makes sedimentary rocks especially useful to scientists and historians?
Sedimentary rock are made of materials that could show what lived where. Also they are the only rock to hold fossils.
What are fossil formed in?
Fossils are formed in sedimentary rocks, which has multiple layers to show the level of soil back then.
What are forming fossils?

What evidence exists about the conditions during precambrian time?
Evidence about conditions during the Precambrian time comes from the study of rocks, fossils, isotopic analysis, and geochemical signatures. Rocks from this era may show mineral deposits, sedimentary layers, and fossil records of early life forms. By analyzing isotopic ratios and geochemical compositions of rocks, scientists can infer details about the atmosphere, ocean chemistry, and temperature during that time.
Can igneous and sedimentary both form fossils?
In certain cases some igneous rocks can show the impression of a living organism, as in the case of trees being encased in lava flows or pyroclastic flows preserving the shape of a human as in Pompeii. Normally however, fossils are found in sedimentary rocks.
What are planar rocks?
Planar rocks are rocks that have layering or bedding planes, which are flat surfaces where the rock has split or been deposited in distinct layers. These layers can be caused by sedimentation, metamorphism, or other geological processes. Planar rocks are commonly found in sedimentary and metamorphic rocks.
Write the terms in the correct order in the flowchart to show how a clastic sedimentary rock forms?
Clastic sedimentary rock forms when fragments of preexisting rocks are compacted or cemented together. Organic sedimentary rock forms from the remains of plants or animals. Chemical sedimentary rock forms when minerals precipitate from a solution or settle from a suspension.
