A 20 mile band that surrounds the earth and
contains all life is known as the __________.
T or F Ancient Earths atmosphere consisted of a
lot of oxygen
10

False - very little oxygen
Biosphere
11
How many years ago did the first
organism(protocells) appear on earth? ___
billion years ago
Earths early atmosphere contain very little
________gas?


12


3.5 to 3.9 billion years ago
Oxygen - 21
13

Name 1 of the 2 types of dating discussed in the
chapter?
What is the process that occurs in all living
things that produces CO2?

14
Relative or radiometric
15

How old is the earth? 3.8 billion years old 4.2
billion years old 4.6 billion years old or 4.6
million years old

What part of our atmosphere do planes fly in ?
16
4.6 billion years old
17
T or F Only a small fraction of all the species
exist today about 99 species of species are
extinct


What part of the atmosphere contains most of the
earths air currents?
18
True
19
Where in the United States is there a great
example of sedimentary rocks. Its a great
example of relative dating. Yellowstone New
Jersey Yosemite Grand Canyon


What layer of the earth contains the ozone?
20
Grand canyon

21
In the grand canyon where would the oldest
fossils been found. TOP MIDDLE BOTTOM


Do clouds and snow reflect or absorb sunlight?
22


At the bottom
Reflects - cooling the Earth
23
On the geological time scale what era did humans
evolve? Precambrian Paleozoic Mesozoic Cenozoic


True or False The earth is closest to the sun in
the summer
24
cenozoic

25
Vertebrates first evolve in the
_________era. Precambrian Paleozoic Mesozoic Ceno
zoic


Another name for zero degrees latitude is
26
paleozoic

27
T or F In the Precambrian era only unicellular
prokaryotes exist

Why does the equator get so much rain?

28
False- Multicellular eukaryotes

At zero degrees the equator heats up fast and the
heat rises as it cools it releases rain..
29
The idea that nonliving material can produce
life. Biogenesis Spontaneous generation
Spontaneous combustion


The Great Basin Desert in the U.S. is a desert.
How does a mountain range develop this dry
condition?
30

On the west side of the mountain moisture is
released as it climbs east side-dry air comes
down an takes moisture out of the earth
Spontaneous generation

31
In Redis experiment what was used as the
independent variable?


Flies Meat Maggots Covered jar June 21
32

Towards
Covered jars

evolved into complex organic molecules. Which are
carbs, nucleic acids and_____.

of CO2 levels in Hawaii ?
34


Proteins
35

What era did dinosaurs roam the
earth? Precambrian Paleozoic Mesozoic Cenozoic

Why do CO2 levels rise during the winter?
36

Mesozoic
37
What era did life first evolve ? Precambrian Pale
ozoic Mesozoic Cenozoic


Name one greenhouse gases.
