Why are fossils found in only sedimentary rocks?
Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperatures and pressures that do not destroy fossil remains. Dead organisms can become sediments which may, under the right conditions, become sedimentary rock. Igneous rock forms from magma; no chance for fossils to form there. Metamorphic rocks are other rock types that are changed by heat and pressure; their transformation and mineral reorganization causes very few fossils to be found there. Sedimentary rock can be formed from the accumulation of sediments and are often formed near ancient shores, basins, and lake beds. If an organism dies and is covered by sediments before being rotted or eaten by predatory organisms, it could eventually become part of the sedimentary layer that becomes rock
What do sedimentary rocks have that allow oil and gas to accumulate in them?
Oil and gas does not accumulate in sedimentary rocks. What happens is that animals or plants die, and their fossils become covered with layers of sediments (dirt and stuff). Over millions of years, after many many layers have built up, those sediments become rock, and the pressure of all that rock on the fossils slowly turns them into oil. That's why oil is considered a fossil fuel. Oil and gas does not accumulate in sedimentary rocks.

Why are the frigid temperatures of Siberia and the sticky tar La Brea Tar Pits preserve fossils so well?
The frigid temperatures of Siberia slow down the decomposition process, allowing fossils to be preserved in ice. The sticky tar at La Brea Tar Pits traps animals that become stuck, preserving their remains over time. Both environments create conditions that inhibit decay, leading to the good preservation of fossils.
What will become of the animals if humans pollute the earth?
If humans continue to pollute the earth, animals will face habitat destruction, reduced food sources, pollution-related illnesses, and extinction. It will disrupt ecosystems and lead to a decline in biodiversity. Efforts to protect and preserve habitats and reduce pollution are crucial to ensure the well-being of animals.
What is a rock formed from the remains of living things called?
A rock formed from the remains of living things is called a sedimentary rock. This type of rock is formed through a process known as lithification, where sediments such as dead plants or animals accumulate and become compacted over time. Examples include limestone, coal, and chalk.
Why do plants and animals do not become fossils?
why do you think many animals and plants did not become fossils
Why do most plants and animals do not become fossils?
why do you think many animals and plants did not become fossils
What animals don't become fossils?
Any internal organs. Only bones become fossils.
What conditions are necessary for animals and plants to become fossils?
The animal or plants needs to be covered in a sedimentary silt or mud, for a very long time.
Do fossils eventually become rocks?
Yes because they will disintegrate
What happens to animals that become extinct?
Animals that become extict have fossils or bones left from when they die.
Can some plants and animals become fossils?
yes!
Why don't all dead plants and animals become fossils?
They are under Uberpressure and heat cannot be decomposed before they are covered by rocks. Most of the time they do rot away though.
How long did it take for animals to become fossils?
1000 years
Is it possible for people to become fossils?
Yes, just the same as fish and animals have become fossils. It may take many thousands of years.
What two things do fossils need to form and why do only some animals become fossils and not all?
For a deceased animal to fossilize its needs to be covered in sediment right after it passes away. Sediment can included, the sea floor, lava and even sticky tar.
Is a dinosaur footprint a fossil?
a footprint.
