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.
The sustainable development means water is use at a rate that won't reduce the amount casinos for future use.
The correct answer is c. water freezes in a crack in a rock.
The water freezes which makes its volume greater so it breaks the rock so then the water thaws and then new water comes, even more of it, so it freezes, and so on and so forth until the rock breaks completely.
