Good job and good job explaining

i know that they lived along time ago and they died because an astroid and a mass extinction is for example if one type of animal dies like only five that normal but if they all died thats a mass extinction.

I know that mass extiction is about that alot of species died at that time . Also that dinosaurs where extict along time ago and that some dinosaurs were friendly and some were nice .

I know that the dinosaurs were extinct many many years ago the became extinct because there were many periods in which they started going extinct.

Mia Navarro

What I know about mass extinctions is when one mass extinction occurs, the environment can change, and create new forms of life with help of genetic mutations and evolution. As an example, mammals!

Bryanna Salazar

2015-08-17 16:10:23 UTC

I know that Mass extinction was when many types of animal species were being extinct.

A mass extinction is when a entire species goes extinct,just like the dinosaurs did. Another thing that happens is that when a mass extinction occurs it ends a certain time period ends.

Khalil williams @Steven Argueta

2015-08-17 16:09:15 UTC

mass extinction is a whole species dies out. cause not thing like that animal lives any longer. like if tigers had an mass extinction no of them had died out like 10,000 to 0 thats an mass extinction

Steven Argueta

2015-08-17 16:09:37 UTC

A mass exstinction is when a whole bunch of animals are wiped out at once like when the dinosaurs got wiped out at once.
