Geologists use the presence or absence of fossil species to determine the age of sedimentary rocks around the world. In the above diagram each vertical bar represents the period of time that a species (A,B,C,D,...) was present on Earth before it speciated (line divides) or went extinct (line ends). Please use this diagram to answer the following question.
What is a potential age for a sedimentary rock that contains fossils of species J andD?
Question 22 options:
65 million years old
72 million years old
76 million years old
90 million years old
How would you characterize atmospheric conditions if the adiabatic lapse rate is steeper than the environmental lapse rate (i.e., a rising parcel of air will always be hotter than the surrounding air at a given height above Earth's surface)?
Question 23 options:
Absolute atmospheric instability
Conditional atmospheric stability
Absolute atmospheric stability
