Fossils are formed in different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.

# data[].attributes.body
how were fossils formed?

# data[].attributes.body
I also have a question about when and how fossils are formed?

# data[].attributes.body
Ozone in the Earth's stratosphere is created by ultraviolet light striking ordinary oxygen molecules containing two oxygen atoms (O₂), splitting them into individual oxygen atoms (atomic oxygen); the atomic oxygen then combines with unbroken O₂ to create ozone, O₃.

# data[].attributes.body
I don't have any.

# data[].attributes.body
that oxygen wasnt made until later on

# data[].attributes.body
How did the ozone layer form?

# data[].attributes.body
dont have any

# data[].attributes.body
my question is, how does it look when ocean life first started, was it colorful?

# data[].attributes.body
dont have any

i learned that earth has been forming for a very long time

# data[].attributes.body
Nothing

I learned a lot about when everything appeared like dinosaurs they came pretty close to us.

# data[].attributes.body
dinosaurs lived closer to humans

# data[].attributes.body
How long it took to get oxogyn

# data[].attributes.body
I have no questions.

# data[].attributes.body
I wonder how everything appered like plants and animals because how did the first animal appear

# data[].attributes.body
One question I have about fossils is what is the difference between paleontology and archaeology? And what do they specifically mean?

# data[].attributes.body
That oxygen wasn't made until a while after earth was made.

# data[].attributes.body
What surprised me most was how oxygen and everything related was made later on.

# data[].attributes.body
tbh, nothing really surprised me about this model.
