ACING EAPS 100 WITH ESSENTIAL A+ QUESTIONS AND
ANSWERS
The cycling of chemical substances throughout the biosphere is accomplished
through:
the work of living things and physical and chemical processes.
Earth science can help us learn about Earth's past by studying:
why continents and oceans are different.
why a landscape looks the way it does.
how life in the past was different than today.
how global climate has changed since the ice ages.
All of these choices are correct.
The Moon and Sun cause the tides in Earth's oceans because of:
gravity.
The difference between open and closed systems is that:
open systems can acquire matter and energy, but closed systems cannot.
What type of map is shown here? Hand sketch with circles
topographic map with contours
The largest object in the solar system is:
the Sun.
Quantitative data may include
specific temperature data.
size measurements of sediments.
chemistry of water in a stream.
age of a rock.
All of these choices are correct.
Which potential geologic hazard is NOT represented by a feature on this figure?
Volcano surrounded by mountains with stream coming out to front corner
contaminated groundwater
Which of the following is an example of quantitative data?
North America is moving across Earth's surface several centimeters per year.
,Continental ice sheets were more common 28,000 years ago than they are today
because:
the Earth was cooler then than now.
Which of the following are ways that the atmosphere interacts with Earth's
surface?
Liquid water on the surface can evaporate, becoming water vapor in the atmosphere.
The atmosphere includes a low percentage of water vapor, most of which comes from
the oceans.
Earth's atmosphere blocks most of the Sun's harmful ultraviolet radiation.
Some energy that strikes the earth is converted into infrared energy.
All of these choices are correct.
What steps are involved in having a hypothesis become an established theory?
The hypothesis is consistent with new data and investigations used to test its
predictions.
In the rock cycle, sediment is stripped away and transported by the process of
________blank after the process of ________blank has taken place.
erosion; weathering
A snowball that rolls down a hill, gradually gaining more and more mass and
rolling faster and faster as it continues, would be an example of a(n):
positive feedback system.
Rates in Earth system processes:
span the range from very rapid to very slow.
The Earth's orbit around the Sun is almost circular. Therefore, Earth receives
about the same amount of year-round
heat and light.
What type of map is shown here? Plain white/offwhite map with shaping
shaded-relief map
Which of the following statements is true about the transfer of energy, matter, or
momentum in the atmosphere?
Energy transfer occurs when water changes state between solid, liquid, or gas.
, What specific type of map represents the distribution of rock units and geologic
features exposed on the surface?
geologic map
Which of these minerals could be used to make glass windows?
quartz
Which of these minerals would you use to make wallboard for the interior walls of
your house?
gypsum
Which of these minerals would be the main component in the cement slab in your
house?
calcite
The image shows bonding for diamond (on the left) and graphite (on the right).
Both minerals are made of carbon, so why do they have very different properties
(why is graphite so soft while diamond is so hard)?
Covalent bonds in both minerals are very strong, but intermolecular bonds between
sheets in graphite are very weak.
The most important class of rock-forming minerals on Earth is
silicates.
Minerals have an ordered internal atomic arrangement. What does this mean?
Atoms in a mineral are arranged in an ordered geometric pattern.
Which mineral property is the least reliable for identifying a mineral?
color
What characteristic of water helps it cause a mineral, such as halite, to dissolve?
the polar nature of the water molecule
In which of the following types of bonding do atoms share one or more
electrons?
covalent
The mineral halite has cube-shaped crystals because
of the arrangement of atoms in the crystal lattice.
In which of the following types of bonding do atoms share one or more electrons,
as shown in this figure?
