Relative-age dating
Transitional fossil A fossil that has characteristics of both ancestral organisms and organisms that don't evolved later.
True
False
Do fossils need to form ???
Yes
No
What is fossil formation
Non of the above
when plant and animals die ,ANY SOft skin are eaten by scavengers or break down by bacteiria.
when plant and animals die ,ANY SOft tuissue are eaten by scavengers or break down by Animals .
when plant and animals die ,ANY SOft tuissue are eaten by scavengers or break down by bacteiria.
What are the words we talked about this lesson
Relative-age dating
Absolute-age dating
Number age
Fossile ageing
What is Relative-age dating
Non Of the above
Soft tissues eaten by scavengers
Relative relative-age dating helps
scientists determine the relative
order in which species have
appeared on earth over time
Absolute-age dating
is more precise
that relative-age
dating.Scientists
take advantage of
radioactive decay
, a natural clock
like process in
rocks to learn
rocks absolue age

What is Trace Fossils and Mineralization
In carbonization, pressure drives off a dead organism's liquids and gases .Only the carbon outline, or film, of the remains.
When sediments hardened around this buried trilobite, a mold formed.Molds uasually show hard parts such as shells or bones.
rock forming minerals such as calcium carbonate (CaCO3) in water filled in the small space in the tissue of these pieces of petrified wood. Mineralization can preserve the internal structure of an organism
if original tissues of orginisms are buried in the absence of oxegen for long periods of time they can fossiliz
What are fossils
Non of the above
Fossils are the geologically altered remains of a once-living organism
Fossils are the geologically altered remains of a once-living Animal
Fossils are the geologically altered remains of a once-living Human
Absolute-age dating is more precise than realative-age dating.Scientists take advantage of radioactive decay , a natural clock like process in rocks to learn rocks absolue age

False
