Earth Space Science Final UPDATED
Exam Questions and CORRECT Answers
Which of the following natural phenomena is partly caused by Earth's revolution around the
sun? - Correct Answer- eclipses, seasons, and solstices
Which organisms live in the neritic zone? - Correct Answer- phytoplankton
How do many transition zone organisms obtain food? - Correct Answer- They periodically
rise up to the neritic zone to feed
What ocean floor feature is found closest to the abyssal plain? - Correct Answer- Continental
Rise
Choose the words that best complete the sentence: Ocean surfaces currents are caused
by________, and deep ocean currents are caused by_________. - Correct Answer- wind;
density differences
Scientists once hypothesized that the universe has always existed in its current state, with a
constant average density. Does the big bang theory support this hypothesis? - Correct
Answer- No. According to the big bang theory, the universe is expanding from its origin as an
infinitely dense point.
An increase in the temperature of ocean water would most likely cause? - Correct Answer- a
decrease in density
Which of the following does not affect the movement of ocean water? - Correct Answer-
abundance of phytoplankton
Where is there the greatest seasonal variation in ocean water characteristics? - Correct
Answer- in a temperate climate
Can humans see the entire electromagnetic spectrum? - Correct Answer- no, visible light
makes up only a very small part of the electromagnetic spectrum
, Which of the following is evidence that supports the big bang theory? - Correct Answer- The
redshift of most galaxies, the measurable expansion of the universe, and the existence of
cosmic background radiation all provide evidence for the big bang theory.
Which of the following planets would likely experience the largest tides? - Correct Answer-
one that has liquid groundwater but no surface water or moons
What causes the trade winds? - Correct Answer- Surface air moves toward low atmospheric
pressure at the equator and is deflected to the west by the Coriolis effect.
In what form does electromagnetic (EM) radiation travel? - Correct Answer- waves
The most abundant gas in Earth's atmosphere is? - Correct Answer- Nitrogen
In the 1700s and 1800s, large sailing ships commonly sailed from port and out to sea at night.
What is the most likely reason for this? - Correct Answer- a land breeze blows out to sea at
night
Which of the following is NOT a part of the electromagnetic spectrum? - Correct Answer-
sound waves
A star's absolute magnitude is defined as? - Correct Answer- the brightness of the would have
at a distance of 32.6 light years from an observer
Which of the following statements is true about the electromagnetic radiation that appears as
white light? - Correct Answer- it is a blend of many different wavelengths of visible light,
each of which corresponds to a different color
Optical telescopes are sometimes launched into Earth's orbit to escape distortion from dust
particles and light pollution. Why are some types of non-optical telescopes launched into
space? - Correct Answer- many wavelengths of the EM spectrum cannot penetrate Earth's
atmosphere
Which of the following most accurately compares and contrasts the different layers of Earth's
atmosphere? - Correct Answer- in the troposphere and mesosohere, temperatures steadily
