Origin and
Evolution of
Earth
- Origins
- How did Earth and
other planets form?
- Sun and planets all coalesced
out of the same nebular cloud
- What happened
during Earth’s
“dark age”?
- Creation of Earth’s Moon
- Earth’s atmosphere, oceans, and
differentiated layers of core, mantle,
and outer crust developed
- How did life begin?
- Darwin: new species arise by the
modification of existing ones
- Scientists: Life came from nonliving
precursors
- Earth’s Interior
- How does it work, and
affect the surface?
- Their internal and surface
processes gradually change
- Development of
mountains and volcanoes
- Why does Earth
have plate tectonics
and continents?
- Continents: features that make Earth habitable
- Plate Tectonics: Earthquakes, volcanic eruptions, the formation of
mountains, and the slow drift of continents over Earth’s surface.
- How are Earth processes
controlled by material properties?
- by the high pressures and temperatures of Earth’s interior,
- by the enormous size of the planet structures
- by the long expanse of geological time,
- Earth’s Climate & Habitability
- What causes climate to change
and how much can it change?
- Emissions of CO2 and
other greenhouse gases
- Warming or cooling can occur in
periods as short as decades or centuries
- How has life shaped Earth and
how has Earth shaped life?
- High levels concentration of oxygen
- Organisms catalyze reactions
- Living with an Active Earth
- Can earthquakes, volcanic
eruptions, and their
consequences be predicted?
- We may never be able to predict the exact time and place
- How do fluid flow and transport
affect the human environment?
- Depends on understanding fluids
- The next objetive is produce
mathematical models that can predict
the performance of natural systems
