of using the present to study the past and
when did he come up with this idea?
• Lyell’s views about uniformity were in direct
contrast to what popular beliefs?
• Compare actualism and uniformitarianism
Biogeochemical Cycles
• Define biogeocemical cycle
• Are biogeochemical cycles considered open or
closed systems? Explain.
• What elements are the primary focus of
scientists studying biogeochemical cycles?
• What are the key concepts considered when
studying biogeochemical cycles?
End of the Line for a Star Like Ours
• Define a Main Sequence Star
• Explain the relationship between a star’s mass and how
long it will survive
• How big is the Sun compared to other stars
• What do you think will happen to the Earth and other
planets in the solar system as the Sun grows to redgiant-star size with a diameter many times that of the
Sun’s present size
• How do gravity and the nuclear processes involved in a
star’s energy production relate to the lifecycle of stars?
• Describe the life cycles of stars based on their mass.
Formation of the Earth’s Atmosphere
and Ocean
• Summarize the three hypotheses for the
formation of the atmosphere and ocean
• Compare the age of the atmosphere and
ocean
• Compare the formation of the atmosphere
and ocean
• Describe how the atmosphere and ocean have
changed over time
•
What is the Fate of Life on Earth
• Why is it unlikely that life will continue until
the end of the solar system?
• What three problems will challenge the future
of life on Earth
How Old is the Universe
• When were scientists finally able to approximate the
age of the Universe?
• What tool enabled scientists to accurately approximate
the age of the Universe?
• Prior to this time, what range existed for the age of the
Universe?
• Why do astronomers think that the age of globular
clusters is approximately the age of the Universe?
Note: globular clusters are groups of stars all tied
together by gravity.
• Describe how scientists finally determined the age of
the Universe. What is that age?
How Did The Big Bang Happen
• What evidence exists to support the Big Bang
Theory?
• What tools are used to collect and test this
evidence?
• Why is the question “What came before the Big
Bang” outside the realm of science?
• Describe the first second of the Big Bang using a
timeline?
• What was the result of the Big Bang?
What is the Fate of the Universe
• Who was the first person to really challenge the
foreverness of the Universe?
• What evidence did this person provide for a finite
Universe?
• Describe the three (3) scenarios for the fate of the
Universe that were popular in the 1980’s.
• What is the Inflation Hypothesis?
• What does a study of white dwarf stars tell us about
the Universe? (Note: White dwarf stars are old, cold
stars).
• What is the most likely scenario for the fate of the
Universe and on what does this scenario depend?
Formation of the Solar System
• Compare the five different theories for the
formation of the solar system.
• Describe some of the different methods used
to date the Earth and the Solar System
• Describe the Nebular Hypothesis
How Did The Moon Form
• Compare Earth’s moon to the moons of other planets
• Describe the early theories for the formation of the
moon
• Why were the Apollo missions so important in revising
theories about moon formation
• Compare Earth’s moon to the moons of other planets
• Describe the early theories for the formation of the
moon
• Why were the Apollo missions so important in revising
theories about moon formation
How Did Galaxies Form
• Which came first – galaxies, stars, or black
holes
• Describe the “infant” Universe
• Describe the ELS Model and the Megerer
Theory of galaxy formation
