Quiz 1

Question 1

Evolution

Answer 1

is a biological change through time

Question 2

What’s a fossil?

Answer 2

-rock evidence of past life!

Question 3

Body Fossils

Answer 3

(skeletal parts)
-only able to come from animals,
-carbonized impressions organic compounds removed thin carbon film remains
-insect in amber

Question 4

Trace fossils

Answer 4

something lived through the behavior of the life form
-footprint

Question 5

Anoxic environment

Answer 5

an environment where there is little to no oxygen allowing the preservation of things

Question 6

rock

Answer 6

A rock is a natural solid made of minerals
-An element is really just an atom!

Question 7

Earth Chemistry

Answer 7

In the whole earth iron is overrepresented however it is created by iron silicon and oxygen

Question 8

Minerals NCLIS

Answer 8

-Natural
-Crystal shape is the actual shape of the rock
-Lattice how the elements are arranged at the atomic level
-Inorganic
-Solid
-The atomic pattern of minerals is called a crystal lattice

Question 9

Silicates

Answer 9

-minerals full of silicon and oxygen

Question 10

Silicon tetrahedron

Answer 10

-Molecule that is made up of silicon and oxygen in the arrangement SIO4
-The one exception to this is quarts
-SIO4 is the bond

Question 11

-relative dating method

Answer 11

GA= gigga atom (billions of years)
MA= mega atom (millions of years)
KA= Killa atom (thousands of years)
Relative data method- “law of superposition”
-also known as the layer cake rule
Law of Superposition- younger layers are on the top oldest layers are on the bottom

Question 12

strata

Answer 12

a layer of rock or sediment

Question 13

Numerical dating methods

Answer 13

-Radiometric dating determines the number of years since a layer was formed
-Radiometric dating through isotope analysis of radioactive decay

Question 14

Isotope

Answer 14

• an alternative form of an element

Question 15

Radioactive decay

Answer 15

a parent isotope into a daughter isotope at a constant rate

Question 16

Half-Life

Answer 16

time required for half of the parent to decay to the daughter

Question 17

Stratigraphy

Answer 17

the branch of geology concerned with the order/relative position of strata and their relationship to the geological time scale.

Question 18

Geologic time units

Answer 18

eons, eras, periods, epochs, and ages

Question 19

Lithostratigraphy

Answer 19

classification of rock based on the observable properties of the strata

Question 20

Biostratigraphy

Answer 20

stratigraphy concerned with fossils and their use in dating rocks

Question 21

Sedimentary environments

Answer 21

places where processes and conditions form the characteristics of sediments and sedimentary rocks (a place/location/area with certain conditions)

Question 22

Sedimentary rock

Answer 22

a rock that forms from pre-existing particles or by chemical precipitation can come from just about anything as long as the material is able to be broken up

Question 23

Continental shelf

Answer 23

portion of a land mass that extends out between an ocean or a sea

Question 24

Sandstone

Answer 24

clastic rock that forms on the ocean floor or on lake or river floors

Question 25

Limestone

Answer 25

is a biochemical rock that forms on carbon shelves on beaches
