EARTH SCIENCE COMPREHENSIVE STUDY
GUIDE 2026 FULL QUESTIONS AND
SOLUTIONS GRADED A+
◍ What are terrestrial planets?.
Answer: The inner four planets with solid, rocky surfaces, including Earth.
◍ climate.
Answer: average weather for a particular region
◍ What does GIGO stand for in scientific research?.
Answer: Garbage In, Garbage Out; emphasizing the importance of quality
data in research.
◍ Atmosphere dry gases (4).
Answer: (N2) Nitrogen - 78.09%(O2) Oxygen - 20.95%(Ar) Argon -
0.93%(CO2) Carbon Dioxide - 0.03%
◍ meteorology.
Answer: the scientific study of Earth's atmosphere, especially in relation to
weather and climate
◍ Name one ancient culture that studied Earth. How were the activities of this
culture similar to the activities of Earth scientists today?.
Answer: Ancient Greeks studied rocks and minerals. Like Earth scientists
today, the ancient Greeks recorded what they discovered so that this
knowledge could be shared.
◍ What does space science encompass?.
Answer: The study of planets, stars, and other objects, processes, and
phenomena in the Universe.
◍ fossil.
, Answer: the remains or impression of a prehistoric organism
◍ Stratosphere.
Answer: - little water here- clouds are rare- OZONE LAYER- air temp =
constant, increases with height (absorbs solar energy & ultraviolet rays from
ozone layer)
◍ Stars.
Answer: - ball of hot, glowing gas- hot/dense enough to trigger nuclear
reactions- nuclear rxns = how the star is fueled- most stars have > masses
than sun, but sun is closer- need mass to trigger nuclear rxns 2 create
energy- less mass = planets or brown dwarfs
◍ plate boundary.
Answer: area where tectonic plates meet and volcanoes and earthquakes
tend to be found
◍ metamorphic rock.
Answer: rock formed from heat and pressure changing the composition of
rocks
◍ Fault-block mountains.
Answer: - Utah, AZ, NM- plate mvmnt = tension forces- normal faults,
hanging wall slides down
◍ rotation.
Answer: when an object spins in a circle
◍ Oblique- slip faults.
Answer: - vertical & horizontal movement
◍ What are the sources of energy that drive Earth sciences?.
Answer: Internal energy (residual heat, gravity, radioactivity) and external
energy (solar radiation).
◍ water cycle.
Answer: movement of Earth's water through evaporation, condensation and
precipitation.
, ◍ Luminosity.
Answer: - total amt of energy radiated by the star per second- watts
◍ How does Earth fit into a larger context?.
Answer: Earth is one planet in a solar system, which is part of a galaxy, and
that galaxy is part of a larger universe.
◍ Reverse faults.
Answer: - rock above fault plane moves up- thrust faults
◍ What is the importance of geologic curiosity?.
Answer: It enhances understanding of the world, including the formation of
landscapes and the origins of materials.
◍ How has technology affected the work of astronomers?.
Answer: Astronomers use technology such as telescopesand spacesuits in
order to observe objects in space that people are not able to study with just
their senses.
◍ Deposition.
Answer: - sedimentation- material deposited from 1 area to another
◍ Red giant / Super giant.
Answer: -dying star- hydrogen is exhausted, core collapses, temp rises-
released heat produces helium
◍ Carbon dating.
Answer: - used to calculate the age of a fossil
◍ Mountain formation.
Answer: - folding- faulting
◍ Asteroids.
Answer: - found btwn Mars & Jupiter
◍ 3 Types of Volcanic Mts..
Answer: - shield volcanoes- cinder-cone volcanoes- composite volcanoes
◍ Trench.
