A.
the process by which plants and animals that can adapt to changes in their environment are able to survive and reproduce while those that cannot adapt do not survive
B.
the true age of a rock or fossil
C.
each of several large landmasses (notably Pangaea, Gondwana, and Laurasia) thought to have divided to form the present continents in the geological past.
D.
a core sample that is typically removed from an ice sheet
E.
a process in which a section of the earth's crust is folded and deformed by lateral compression to form a mountain range.
F.
the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.
G.
The geological process by which the Earth came to have its present interior structure
H.
a distinctive and typical style, form, or character.

states that layers of sediment initially extend laterally in all directions; in other words, they are laterally continuous

process of fossilization in which mineral deposits form internal casts of organisms

a surface of contact between two groups of unconformable strata.
M.
a fossil that is useful for dating and correlating the strata in which it is found.
N.
states that layers of sediment are originally deposited horizontally under the action of gravity
O.
an object made by shaping molten metal or similar material in a mold
P.
help determine the chemical composition and age of minerals and other geologic objects.

incorrect
21.
the gradual development of something, especially from a simple to a more complex form.
incorrect

incorrect
23.
the theory that changes in the earth's crust during geological history have resulted from the action of continuous and uniform processes.

To remove embedded gas from (a solid), as by heating or reducing the pressure
incorrect
27.
a fossil of a footprint, trail, burrow, or other trace of an animal rather than of the animal itself.
