What is it that tells a geologist when where and how an organism lived?
a blank is the cavity left behind in the rock after an organism hard part has dissolved
Which features help explain why a certain organism fossilized so abundantly?
Three Reasons: 1) The organism lived/lives for a large period of time (species was/is in existence for a long time) 2) The organism lived/lives over a vast geographical range (species lived/lives in more than just a few specific areas) 3) The organism has/had hard parts (ex: bones)
What may tell a geologist when where and how an organism lived?
Geologists can infer when, where, and how an organism lived by examining fossilized remains, which provide information about the organism's structure and age through radiometric dating. Sedimentary rock layers can indicate the environment in which the organism existed, such as aquatic or terrestrial settings. Additionally, the presence of specific isotopes or trace elements in the fossils can reveal insights into the organism's diet and the climate of the period. Overall, the context of the fossil within its geological setting is crucial for understanding its life history.
Which is not a factor in a fossil organism being useful as an index fossil?
it must have lived through a long span of time
How long an organism lived?
An organism's lifespan can vary significantly depending on its species, environment, and genetic factors. Some organisms, like the mayfly, live for only a few hours, while others, like the bowhead whale, can live for over 200 years. It's essential to consider the specific organism in question to determine its typical lifespan.
