CHAPTER 1
ST
The Earth in Context
UV
Learning Objectives
1. Students should be aware of the Big Bang theory. Distant galaxies are all moving
IA
away from us. The farthest galaxies are receding from us the fastest. All matter in the
Universe was contained in a single point, approximately 13.8 billion years ago. At
_A
that time, the Universe explosively came into existence.
2. Stars, including our Sun, are nuclear-fusion reactors. For most of their life histories
(on the order of billions of years), hydrogen atoms are fused together to form helium.
Later stages in stellar evolution include fusion of helium atoms and other, heavier
PP
elements; ultimately, iron is the heaviest element that can be produced through fusion
reactions within stars.
3. After their cycles of fusion are complete, large stars violently explode (forming
RO
supernovas), producing elements heavier than iron and leaving behind a residue of
diffuse nebulae, which may be recycled to form a new star at some future point.
4. Our Solar System is approximately 4.57 Ga (billion years old). All eight planets
revolve around the Sun in coplanar, elliptical orbits. All planets orbit in the same
VE
direction (counterclockwise, as viewed from above Earth’s North Pole). These facts
imply simultaneous planetary formation from a swirling nebula surrounding the Sun
(the similarities in orbits would then be a natural result of conservation of angular
D?
momentum). The planets accreted from this nebula through gravitational attraction
and haphazard collisions. Pluto, long considered the “ninth planet,” has seen its status
demoted; astronomers now recognize eight major planets.
?
5. The terrestrial planets (Mercury, Venus, Earth, and Mars) are relatively small, dense,
and rocky worlds. The giant planets are predominantly composed of the light gases
hydrogen and helium (Jupiter and Saturn) or ices (Uranus and Neptune); they are

, much larger and much less dense than the terrestrial planets.
6. Our Moon is thought to have originated from debris accumulated when a protoplanet
collided with Earth approximately 4.53 Ga.
7. The Earth System is subdivided into the atmosphere (gases and aerosols that envelop
the planet), hydrosphere (Earth’s water), geosphere (solid Earth), and biosphere
ST
(living things).
8. Earth is chemically divided into a thin, rocky crust dominated by silicate minerals, a
thick mantle composed mostly of iron- and magnesium-rich silicates (subject locally
UV
to partial melting), and a thick, metallic core made primarily of iron (the outer portion
of which is liquid). Students should know how seismic waves tell us that the outer
core must be liquid.
IA
9. Physically, the uppermost layers of Earth are the rigid lithosphere (crust and
uppermost mantle) and the asthenosphere, which is weaker and flows plastically. The
“plates” of plate tectonics theory are discrete slabs of lithosphere, which move with
_A
respect to one another atop the asthenosphere.

Summary from the Text
RO
The geocentric model placed Earth at the center of the Universe. The heliocentric
model placed the Sun at the center.
The Earth is one of eight planets orbiting the Sun. The Solar System lies on the outer
edge of the Milky Way galaxy. The Universe contains hundreds of billions of galaxies.
VE
Most astronomers agree that this expansion began after the Big Bang, a cataclysmic
explosion that occurred about 13.7 billion years ago.
The first atoms (hydrogen and helium) of the Universe developed within minutes of
D?
the Big Bang. These atoms formed vast gas clouds, called nebulae.
Only very small atoms formed during Big Bang nucleosynthesis. The Earth, and the
life forms on it, contain elements that could have been produced only during the life cycle
