What is a fossil really?

The remains of an animal after being put under pressure by layers of sediment.

Explanation:

when an animal (or plant) dies, its remains are buried slowly by layers of dirt, sand, small rocks, etc. after the layers are removed, the fossil remains!

The remains can be fully recovered, or they can act as a cast so you can only see the outline of the actual bone or plant rather than the real thing :)

the pogroms became known as kristallnacht, the "night of shattered glass," for the shattered glass from the store windows that littered the streets. the morning after the pogroms 30,000 german jewish men were arrested for the "crime" of being jewish and sent to concentration camps, where hundreds of them perished.

this is because warmer climates often don't get people sick from the flu and regions where it was often colder more people received the flu. hope this if you need more reasoning i am here to
