Which observation best shows that limestone was formed from ocean sediments?
The presence of marine fossils within the limestone is the best observation that shows it was formed from ocean sediments. Marine fossils like shells, corals, or sea creatures preserved within the rock provide direct evidence of its marine origin. Additionally, the presence of ripple marks or cross-bedding in the limestone can also indicate its formation in a marine environment.
Differences between aeolian marine and lacustrine sandstones?
Aeolian sandstones are formed by wind deposition in arid environments, typically showing cross-bedding and poor sorting. Marine sandstones form in coastal or marine environments, showing ripple marks, fossils, and better sorting. Lacustrine sandstones form in freshwater lake environments, often displaying mudcracks and plant fossils.
Do all rocks form fossils?
No, fossils are actually very difficult to find. The majority of fossils found are marine invertebrates. They are usually found in sedimentary rock. However, there is plenty of sedimentary rock that contains no fossils at all.
How do fossils in sedimentary rock help interpret ancient environments?
the type of sedimentary rock determines when other layers in rocks formed and how they shifted. the properties of the species of time periods need certain environmental conditions. these conditions must be what types of environments ancient creatures lived in.
Which are the remains of species that existed on Earth for relatively short periods of time were abundant and were wide spread geographically?
Trilobites are an example of remains from a species that existed for relatively short periods of time, were abundant, and were geographically widespread. Trilobites lived from the Early Cambrian to the Late Permian period, spanning over 270 million years, and were diverse and numerous in marine environments worldwide. Their fossils are commonly found in rocks around the world.
What rock are most marine animal fossils in?
The most marine fossils are found in sedimentary rock
How is possible for the remains of marine fossils to be found in the Alps?
The presence of marine fossils in the Alps is due to the process of plate tectonics. The Alps were formed when the African and Eurasian tectonic plates collided, pushing up the oceanic crust that originally contained marine fossils. This collision caused the rocks containing the fossils to be uplifted and exposed above sea level in the Alps.
What type of rock are marine fossils found in?
sedimentary

What type of sediment would you most likely find fossils of marine life?
Near shore marine sediments.
Why are there marine fossils high in the Andes Mountains?
Use Google and do your Biology homework elsewhere. There are marine fossils high in the Andes Mountains because of layer shifting (which relates to the Law of Superposition), which means that over time, the layers push the fossils upwards. So it all ties into Layer Shifting and how the fossils work.
What does it tell scientists if they find marine life fossils in an area where there is not any water?
It would tell anyone that the rocks which contain the fossils were marine sediments deposited in a sea or ocean below sea level.
Which observation best shows that limestone was formed from ocean sediments?
The presence of marine fossils within the limestone is the best observation that shows it was formed from ocean sediments. Marine fossils like shells, corals, or sea creatures preserved within the rock provide direct evidence of its marine origin. Additionally, the presence of ripple marks or cross-bedding in the limestone can also indicate its formation in a marine environment.
Have More Human Fossils Have Been Found Than Any Other Type Of Fossil?
No, human fossils are among the rarest type of fossils. Fossils of plants and marine organisms are far more abundant and have been found in greater numbers than human fossils.
When was the first fossils of a marine reptile found and what is it?
First found in the 18 century and it was a Mosasaurus
How do fossils show that rock at the top of mountains was once under water?
Fossils found in rock at the top of mountains indicate that the rock was once at the bottom of a body of water because the fossils are typically of marine organisms that lived in water. The presence of marine fossils in mountain rock suggests that the rock was uplifted from below sea level to its current position at the mountain top over millions of years.
