23.
Base your answer(s) to the following question(s)
on the passage below and on your knowledge of
Earth science.
Cosmic Microwave Background Radiation
In the 1920s, Edwin Hubble's discovery
of a pattern in the red shift of light from
galaxies moving away from Earth led to
the theory of an expanding universe. This
expansion implies that the universe was
smaller, denser, and hotter in the past. In the
1940s, scientists predicted that heat (identi ed
as cosmic microwave background radiation)
left over from the Big Bang would ll the
universe. In the 1960s, satellite probes
found that cosmic microwave background
radiation lls the universe uniformly in every
direction, and indicated a temperature of
about 3 kelvins (K). This radiation has been
cooling as the universe has been expanding.
D. a spiral-shaped formation composed of billions
of stars
Scientists infer that the universe began
approximately
22.
Base your answer(s) to the following question(s)
on the calendar model shown below of the inferred
history of the universe and on your knowledge of
Earth science. The 12-month time line begins
with the Big Bang on January 1 and continues to
the present time, which is represented by midnight
on December 31. Several inferred events and the
relative times of their occurrence have been placed
in the appropriate locations on the time line.
A.
1.0 billion years ago
B.
3.3 billion years ago
C.
8.2 billion years ago
D. 13.7 billion years ago

occurred.
Which event occurred approximately 4.6 billion
years ago?
