Which statement best explains how fern fossils could be found in present-day Arctic regions?
Fern fossils found in present-day Arctic regions suggest that the area was once much warmer and more conducive to fern growth, likely during a period of time when the Earth’s climate was different. This points to significant climate change in the region over geological time scales.
An understanding of which of these best enabled scientists to determine the approximate ages of fossils?
The understanding of radioactive decay, specifically carbon dating and other radiometric dating methods, has enabled scientists to determine the approximate ages of fossils by measuring the decay of isotopes within the fossils. This process allows scientists to estimate the age of fossils based on the ratio of isotopes present in the sample.
What is a significant benefit of studying fossils?
1.)They provide an ancestral linkage to modern species. For example, the chordates (which includes we humans) can be traced back to our common ancestry to sea squirts! The fossils record is database for evolution. 2.)They sometimes can explain the ecological roles and modes of life of past organisms, which can be correlated to modern species. 3.)hey can tell us what types of sediment deposits were present, by determining what fossils are found. i.e. marine fossils present indicates it would be a marine sediment and not a land sediment. p.s. i see u right now
Fossil that show how long dead animals change their environment?
Fossils can provide information on how long-dead animals may have influenced their environment by studying their remains and the sediment they are found in. For example, fossilized footprints, feces, or teeth can indicate the type of animals present and their behaviors, which can give clues about their impact on the ecosystem. Additionally, changes in plant or soil composition around fossils can suggest how animals interacted with and modified their surroundings.
Are fossils the most characteristic that is common to metamorphic rocks?
No, metamorphic rock is not conducive to preserving fossils because of the high pressures and temperatures it has been subjected to that destroys organic matter. Most fossils are found in sedimentary rock.
What evidence do fossils provide of the environments past and present?
changes in the environment e.g. the place, temperature, climate.
How much money did Clear and Present Danger gross worldwide?
Clear and Present Danger grossed $207,500,000 worldwide.
What types of fossils forms wheather there are microbes are present or not?
Fossils can form even if microbes are not present. Microbial fossils, such as stromatolites, can form when microbes are present and leave behind structures or chemical signatures that are preserved in the rock record. Non-microbial fossils can include the preserved remains of plants, animals, or other organisms from ancient environments.
Fossils formed when an organism dissolves and leaves an empty space in a rock are called?
Voids left behind by once present fossils are called 'trace fossils'.
How do you suppose geologists in the field find clues about the distribution of rock types?
Discontinuity surfaces (bedding planes and various types of unconformities), significant changes in mineralogy or grain size or changes in the types of fossils present in the rock may all help identify differing rock layers.
What are fossils and early plants similar to?
Lets say if you take any plant of your choice and subject it to extreme conditions of pressure temperature etc., and also aging process then you get some what similar to a Fossil.that is the fossil (considering plant fossils) and other early plants are all "similar" to present day plants (or present day living things) (barring evolutionary changes).Hope this Helps
When were fossils made?
Fossils are created through a process called fossilization, which occurs when an organism's remains are buried under layers of sediment and undergo chemical changes over a long period of time. This process can take thousands to millions of years, with the formation of fossils typically happening in sedimentary rocks.
What do fossils teach us about extinction?
The kind and numbers of fossils found in different kinds of rocks give clues about past ecosystems. Fossils give evidence that, in any ecosystem, some plants and animals survive well, and some do not.
Which statement best explains how fern fossils could be found in present-day Arctic regions?
Fern fossils found in present-day Arctic regions suggest that the area was once much warmer and more conducive to fern growth, likely during a period of time when the Earth’s climate was different. This points to significant climate change in the region over geological time scales.
