a water laid stratum at the time it was formed, must continue laterally in all directions until it things out as the result of non deposition or until it abuts against the edge of the original basin of deposition "Study Blue provides way more features than other studying apps, and thus allows me to learn very quickly!??
The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.
Teaching about Earth's history is a challenge for all teachers.
Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.
Once students begin to grasp "relative" dating, they can extend their knowledge of geologic time by exploring radiometric dating and developing a timeline of Earth's history.
*Life Science: Fossils indicate that many organisms that lived long ago are extinct.
