EARTH 101 || All Answers Are Correct 100%.
Physical Geology is the study of correct answers the materials that compose Earth and the ways
in which they are organized and distributed throughout the planet
a hypothesis must be testable so that correct answers it can be objectively evaluated, its accuracy
can be independently assessed, its ability to make accurate predictions can be appraised, and it is
possible to revise the hypothesis if it does not provide accurate predictions
the rock cycle is correct answers a concept proposing that rocks are naturally recycled
subduction occurs correct answers when one plate slides beneath another, when a plate is
recycles into Earth's interior, when a plate enters the mantle at a deep-sea trench, and when
seafloor is recycles beneath an overriding plate
Hess's mechanism for moving plates was: correct answers mantle convection
mantle convection correct answers was proposed by Hess at the driver of seafloor movement, is
the product of heat flow within Earth's interior, is though to resemble the action in a lava lamp,
and causes rifting and seafloor movement between spreading center and subduction zones
Pangaea is: correct answers the name of an ancient supercontinent
The process of seafloor spreading predicts that: correct answers the oldest seafloor will be found
at subduction zones, seafloor moves like a conveyor belt from spreading centers toward
subduction zones, there is a high heat flow from Earth's interior into the crust at spreading
centers, and continents shift locations because they are embedded in moving plates
plates influence Earth's topography because: correct answers mountain belts form where plates
collide, mid-ocean ridges develop at spreading centers, trenches develop at subduction zones,
and rift valleys mark sites of plate divergence
the three rock groups are: correct answers igneous, sedimentary, metamorphic
geological hazards: correct answers cannot always be prevented but often can be avoided
common geological resources studied by geologists include: correct answers fossil fuels,
freshwater, soil, and building material
as the fossil fuels and economic minerals that are easiest to obtain are discovered and extracted,
mining companies will have to explore for new resources in more difficult to reach locations
such as the deep sea, or the Arctic. This will have the effect of: correct answers making these
resources more expensive
the subdivisions of the geological time scale that represent the greatest expanse of time are
called: correct answers Eons
, The Principle of Uniformitarianism: correct answers states that the study of modern geologic
processes is useful for understanding past events in Earth history
The classical planets in order from the Sun are: correct answers Mercury, Venus, Earth, Mars,
Jupiter, Saturn, Uranus, and Neptune
the name of a hypothesis explaining the origin of the solar system correct answers solar nebula
Planetesimal Accretion is correct answers collisions of bits of ice, gas, and dust grew into
planetesimals, planetary embryos, and, eventually, planets
the basic structure of the solar system is described as correct answers inner terrestrial and outer
gaseous planets
the energy that is destined to become sunlight may take correct answers 1,000,000 years to travel
from the Sun's core to its surface
nuclear fusion correct answers is the source of the Sun's energy
nuclear fusion is causing the sun to weigh less over time (t/f) correct answers True
Mercury, Venus, and Mars are different from Earth because correct answers Earth currently has
liquid water and they do not
Thus far, there has been no direct observation of flowing water on Mars (t/f) correct answers true
Why do the outer planets and their moons consist mostly of ice and gas while the inner planets
are made up mostly of rock and metal? correct answers the solar wind stripped the inner planets
of volatile compounds
the largest storm in the solar system is found on which planet? correct answers Jupiter
The fastest winds in the solar system are found on which planet? correct answers Neptune
the major gases in the solar system include: correct answers Hydrogen, helium, methane, and
carbon dioxide
the outer gaseous giants are characterized by abundant correct answers hydrogen
the inner terrestrial planets are characterized by abundant correct answers silica
comets have two tails. one points ___ the ___ and the other points ___ the direction of travel.
correct answers one points away from the Sun and the other points away from the direction of
travel
