Earth Science
Which two characteristics classify Jupiter as a Jovian planet?
(1) low density and large diameter
(2) low density and small diameter
(3) high density and large diameter
(4) high density and small diameter
(1) low density and large diameter
The key characteristics of Jovian planets include their large size, being made up of mostly gas, and lack of a solid surface. They are distinct from terrestrial planets (like Earth) that are smaller, denser, and have solid surfaces.
What is the term for the study of the decomposition of bodies?
a) Forensic Pathology
b) Forensic Anthropology
c) Forensic Entomology
d) Forensic Odontology
c) Forensic Entomology
As observed from Earth, the wavelengths of light from the most distant galaxies are usually
(1) blue shifted due to an expanding universe
(2) blue shifted due to a contracting universe
(3) red shifted due to an expanding universe
(4) red shifted due to a contracting universe
(3) red shifted due to an expanding universe
This phenomenon is known as cosmological redshift. It occurs because the universe is expanding, causing galaxies to move away from each other. As a result, the light emitted by these galaxies is stretched as the universe expands, leading to a shift of the light towards longer (redder) wavelengths.
What is the term for evidence that can prove or disprove a specific event?
a) Circumstantial evidence
b) Indirect evidence
c) Physical evidence
d) Direct evidence
d) Direct evidence
The rate of Earth’s revolution around the Sun is approximately
(1) 1°/day
(2) 15°/day
(3) 24°/day
(4) 360°/day
(1) 1°/day
Earth completes one full revolution around the Sun in about 365.25 days, which is why we have a year. This corresponds to the Earth moving approximately 360 degrees around its orbit, so on average, the rate is around 1 degree per day.
In forensic science, what does DNA stand for?
a) Deoxyribonucleic Acid
b) Double Nucleotide Analysis
c) Diatomic Nitrogen Atom
d) Digestive Nucleotide Accumulation
a) Deoxyribonucleic Acid
Different star constellations are observed from Earth at different times during the year because
(1) constellations spin on an axis
(2) constellations travel in an orbit around the Sun (3) Earth spins on its axis
(4) Earth travels in an orbit around the Sun
(4) Earth travels in an orbit around the Sun
As Earth orbits the Sun, its position changes relative to the distant stars. This orbital motion causes different constellations to be visible in the night sky at different times of the year. The apparent motion of the stars is a result of Earth's revolution around the Sun.
What is the primary purpose of using luminol at a crime scene?
a) Identify gunshot residue
b) Enhance latent fingerprints
c) Detect bloodstains
d) Analyze drug composition
c) Detect bloodstains
The Milky Way can best be described as
(1) an elliptical galaxy
(2) a collection of stars orbiting the Sun
(3) a star that originated 4600 million years ago
(4) one of billions of galaxies in the universe
(4) one of billions of galaxies in the universe
What is the study of skeletal remains to determine the identity and characteristics of the deceased?
a) Forensic Paleontology
b) Forensic Anthropology
c) Forensic Odontology
d) Forensic Entomology
b) Forensic Anthropology
