Answer:
All dinosaur fossils found by archeologists have been found a few centimeters below the iridium layer. So, the possibility of finding dinosaur fossils above the iridium layer is very slim.
Explanation:
Over 65 million years ago, dinosaurs roamed the earth but were canceled out as a result of an extraterrestrial impact on the earth's crust. Research proved that an asteroid brought the end of dinosaurs as the element iridium was found in the earth (since iridium is abundant in asteroids and not the earth's crust).
Records of fossils found have been between 13 to 60 centimeters below the iridium or the K-T boundary as it is called.
Answer:
For a geographer Map is the most important tool
Explanation:
Apart from the above geographers rely on various tools and techniques which are both Qualitative and Quantitative. Such as the Primary and secondary sources of data like surveys, questionnaires, and journals, etc. Apart from this use of satellite data to generate a comparative analysis of objects and there processing in terms of software i.e the GIS, GPS that store and breaks the data into an understandable format. Use of mental maps to understand the spatial construct of humans and the use of Aerial photography to help the geographers do an in-depth analysis of the landscape.

Answer:
estimated CEC for given hypothetical soil is 26.25 meq/100g.
Explanation:
Average CEC in smectite = 62.5 meq/100g. Since it ranges from(25-100 meq/100g)
Average CEC in kaolinite = 10 meq/100g.
Average CEC in organic matter = 325meq/100g.
Range(250-400 meq/100g).
Estimated CEC for given soil will be,
= 26.25 meq/100g.
