Why are index fossils so important to geologists?
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
Which characteristics of a fossil would you make it useful as an index fossil in determining the relative age of widely separated rock layers?
C). a narrow time range and a wide geographic range
What are the disadvantages of using Myers index?
The Myers Index, while useful for assessing the personality traits of individuals, has several disadvantages. It may oversimplify complex human behaviors by categorizing individuals into fixed types, potentially neglecting the nuances of personality. Additionally, its reliance on self-reported data can lead to biases and inaccuracies, as individuals may not fully understand themselves or may respond in socially desirable ways. Finally, the index may lack predictive validity, making it less effective for certain applications, such as personnel selection or clinical assessments.
What is a glycemic index used to measure?
The glycemic index is used to measure how quickly ones blood sugar rises after eating food. The higher the food is in carbohydrates and or sugar, the more the index rises.
What is an ig index used for today?
An IG Index is used in the United Kingdom. It is used for spread betting for a large range of financial markets. Ig Index is overseen by the Financial Services Authority.
To be useful as an index fossil fuel spices must have existed for how long?
To be useful as an index fossil fuel, spices must have existed for about 1000 years.
Why are the Eurypterids in these cross sections not useful as index fossils?
The Eurypterids in these cross sections not useful as index fossil because they are only found in certain areas are a long lived organism
Is the Glycemic Index Useful?
The Glycemic Index is useful for some people who are struggling to lose weight. It is a study that shows how food in consumed and burned by the body and for some people how the food effects them.
Why are index useful to geologists?
they tell the absoute age of rcoks which they occur
What fossils are useful in determining the relative age of rocks?
Index fossils
What would be helpful for locating useful information in a book?
Table of Contents and glossarythe index and table of contents (APEX)Using the index
What is the use of stomatal index?
The stomatal index is a measure used to quantify the density of stomata (pores) on a leaf surface relative to the total number of epidermal cells. It is useful in assessing plant responses to environmental conditions, such as changes in atmospheric CO2 levels, and can indicate adaptations to different habitats. Additionally, the stomatal index is employed in paleobotany to infer past climates by examining fossilized plant material. This metric helps researchers understand plant physiology and ecosystem dynamics over time.
What must be true for a fossil organism to be useful as a index fossil?
The absolute age of the index fossil was determine by radioactive dating or another absolute method
Is it true that To be a useful index fossil a species must have been rare?
No, an index fossil does not have to have been rare to be useful. The key characteristic of an index fossil is that it is easily recognizable, widespread geographically, and existed for a relatively short period of time. This allows geologists to use it to help date the rock layers in which it is found.
Why are index fossils useful for figure out the age of a set of disturbed rock layers?
index fossils are useful for figuring out the age of a set of disturbed rock layers by index fossils are used to determine when rock layers were formed so if they were used to figure out the age of a set of disturbed rock layers than they can also figure out when they were formed .
Why the book index page is useful?
An index is important because rather than having to flip through an entire book to find a single answer, you can look in the book's index and it will tell you the page where a specific topic is reviewed/discussed.
What are index fossils useful for?
Because organisms that became index fossils lived only during specific intervals of geologic time, geologists can estimate the ages of rock layers based on the particular index fossils they contain.
