How do you know that rock in some mountains formed under water?
Rock which has formed under water and is now appearing on the surface in mountainous areas would exhibit characteristics of sedimentary rocks found in marine settings: strata, marine fossils, and cemented sediments of various sizes and chemistries. Ripple marks could also be present.
What is hydrogenous sediment?
Hydrogenous sediments are formed when minerals precipitate from the ocean, or they can be formed when minerals in the water react with older sediments.
Are most sedimentary rocks formed under water?
Yes, most sedimentary rocks are formed under water. They are commonly created through processes like erosion, transportation, and deposition of sediments in water bodies such as oceans, rivers, and lakes. Over time, these sediments become compacted and cemented together to form sedimentary rocks.
What type of rock fossils are most found?
Fossils will be found almost exclusively in sedimentary rocks. Sedimentary rocks are formed by the compression and cementation of sediments over millions of years. Organisms that die on, in, or near a body of water have a better chance of becoming fossils due to the fact that fossilization requires that the organism be covered relatively quickly in sediments. Once covered in sediments, some of these remains remain intact and can be discovered to have formed fossils or fossilized remains within the layers of the rock. Shale is a particularly good rock for this to occur in, and some limestones like chalk, are composed almost entirely of fossilized marine animal remains.false!sedumntary
What are sediments how are they involved in the formation of fossil?
Sediments are tiny pieces of earth that travel by being carried by either wind, water, or ice. they are involved with the process of fossils since it covers and buries an organism when it dies and eventually settle under great amounts of heat and pressure.
Which environment would most likely not contain fossils?
The vast majority of fossils are found in marine sediments because it is the easiest environment in which to be buried without the original animal or plant rotting or being eaten. Fresh water sediments such as lakes are also good for fossil formation especially when the lake has periodically dried up or a natural disaster has removed a lot of the oxygen from the water. Most fossils of land animals, birds and plants are found in river or lake sediments when the organism has been washed into the water upon death.
How is Aquifer formed?
Water fills up all the pore space in the sediments.
What kind of rocks is formed from sediments deposited in bodies of water?
Sedimentary rock
How are shoals formed?
Shoals are formed by the deposition of sediments and materials transported by water currents, usually in shallow areas of water bodies such as rivers, lakes, or oceans. Continuous movement of water carries sediments and deposits them in specific areas, creating shoals. Over time, the accumulation of sediments solidifies and shapes the shoal.
What is a rock and how is it formed?
A sedimentary rock is formed from sediments, that is particles of preexisting rocks that have been broken down by weathering process and transported to new locations by water, ice or wind. The sediments accumulate over time as layers deposited parallel to the Earth's surface and, as they become buried by overlying deposits, they harden to form rock - sedimentary rock. During their deposition process, they may include burrows, shells or bones of living creatures and these become fossils as the sediments harden.
What kind of habitat that is most likely to be rich in fossils?
According to experts, the best environments to search for fossils are places near rocks or deserts. Most fossils are preserved in these areas.
What characteristics are most common in sedimentary rock?
Common characteristics of sedimentary rocks include layering (stratification), grains or particles of different sizes and shapes (sedimentary structures), fossils, and the presence of minerals like quartz, calcite, and clay minerals. These rocks are formed from the accumulation of sediments that are typically deposited by water, wind, or ice.
