Question

Match each extinction to its appropriate characteristic. 1. Cretaceous-Tertiary possibly caused by forest grow on Earth's land surface 2. End Triassic possibly caused by massive rifting of Earth's surface 3. Permian-Triassic the earliest mass extinction on record 4. Late Devonian worst mass extinction in Earth's history 5. Ordovician-Silurian killed off the dinosaurs

Answer 1

Mass extinction refers to the procedure in which a huge number of species gets extinct suddenly.  

The following are the correct matches of the events taken place in the mentioned time period:  

1. Cretaceous-Tertiary: The mass extinction of dinosaurs took place.  

2. End-Triassic: Possibly resulting due to massive rifting of the surface of the Earth.  

3. Permian-Triassic: It is considered the worst mass extinction in the history of the Earth.  

4. Late Devonian: It is possibly a result of the growth of forest on the land surface of the Earth.  

5. Ordovician-Silurian: The earliest mass extinction took place at this time.
