Meteorite Individual

Anyone......???

A vertical sequence of strata is called a...
strata sequence.
layer post.
strata pillar.
stratigraphic column.

A younger sequence truncating an older sequence is an example of a:
cross-cutting relationship.
discontinuity.
lateral continuity.
gradualistic disconformity.

After two half-lives the number of parent atoms will be reduced to only what percentage of the original number.
0%.
75%.
50%.
25%.

Modern estimates of the age of the Earth are based on the age of:
The oldest rocks found.
The oldest minerals found.
Meteorites.
The oldest fossils found.

Individual rock layers can be correlated from one place to another by:
fossils.
their grain size.
their chemistry.
the principle of superposition.

I'm 99% sure the first one's stratigraphic column.
dont kno the second one

the third is deffinetely 25%
