What accounts for the presence of marine fossils on mountain tops?
There was water there!!
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.
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.
Which of these is the best evidence that the Earth's crust has undergone some major changes?
The presence of marine fossils in mountain rock
Why are marine fossils not found I found in the bedrock of mountains?
Marine fossils are typically not found in the bedrock of mountains because these fossils originate from organisms that lived in ocean environments. Over geological time, tectonic processes can uplift oceanic crust, but if a mountain was formed from continental crust or underwent significant erosion, the marine sediments may have been removed or altered. Additionally, if the area was never underwater, it would not have marine fossils. Thus, the presence of marine fossils in mountain bedrock is contingent upon past geological conditions that allowed for marine life to exist in that location.
What rock are most marine animal fossils in?
The most marine fossils are found in sedimentary rock
What are marine fossils?
fossils are something like a plant or bone preserved in rock, then when the preserved thing finally decays there is an impression left in the rock. marine fossils are marine animals, plants, or shells (basically anything in the water, hence marine) that are now fossils.
What does the presence of marine fossils tell you about the history of the Mojave desert?
The presence of marine fossils in the Mojave desert indicates that the region was once covered by sea millions of years ago. This suggests that the area has undergone significant geological changes, such as shifting land masses or changes in sea levels, leading to the formation of the desert landscape we see today.
What do marine fossils tell us about the history of the Mojave Dessert?
Marine fossils found in the Mojave Desert indicate that this region was once submerged under an ancient ocean, specifically during the Mesozoic era. These fossils, including those of shellfish and other marine organisms, provide evidence of past marine environments and help reconstruct the geological history of the area. The presence of these fossils suggests significant geological changes, including uplift and erosion, that transformed the region from a marine environment to the arid desert we see today. This highlights the dynamic nature of Earth's surface and its long-term climatic and geological evolution.
What can you conclude about a times earth past when only marine fossils formed?
When only marine fossils formed, it indicates that the Earth's surface was predominantly covered by water, suggesting a time when the environment was primarily aquatic. This era likely represents a period before significant landmass development, such as the emergence of continental landforms. The presence of marine fossils also implies that life was largely concentrated in oceans, highlighting the importance of marine ecosystems in the evolutionary history of life on Earth. Such periods can include the Cambrian and Ordovician, when diverse marine life flourished.
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.
