ASTRONOMY 1010 CLEMSON ACTUAL
EXAM 2024-2025 WITH LATEST
QUESTIONS AND CORRECT ANSWERS
ALREDY GRADED A+
What causes the seasons? - ANS-The tilt of the Earth's rotation axis to its orbit around the Sun causes
parts of the Earth to experience more direct illumination from the Sun and longer days during the
summer than the winter.
What part of the Earth spins the fastest? - ANS-the equator
If you were standing at Earth's North Pole, where would you see the north celestial pole relative to your
zenith? - ANS-at the zenith
Astronomers cannot use parallax to find the distance to most stars. This is because the stars are - ANS-
too far away
What is a parallax - ANS--an observer moves between two points of observation
- notes nearby objects appear to move relative to distant (background) ones.
, - this apparent shift of a nearby object can be measured by the angle θ called the parallax
Hydrostatic equilibrium in the Sun means that - ANS-pressure balances the weight of overlying layers
When hydrogen is fused into helium, energy is released from - ANS-conversion of mass to energy
The International Space Station flies overhead. Using a telescope, you take a picture and measure its
length to be _______
than its length as it would be measured if it were sitting on the ground. - ANS-slightly less
If the star Polaris has an altitude of 35°, then we know that - ANS-our latitude is 35° north.
What phase occurs directly after a new moon? - ANS-waxing crescent
A lunar eclipse occurs when the ________ shadow falls on the ________. - ANS-Earth's; Moon
Assume that you and your sister can both throw a baseball at a speed of 60 km/h. If you are in an
airplane traveling at 700 km/h and play catch with your sister who is near the front of the plane (you
being toward the rear), how fast would the ball be traveling as seen by an observer on the ground when
you throw the ball? - ANS-760 km
How fast would the ball be traveling as seen by an observer on the ground when your sister throws the
ball back to you? - ANS-640 km
When Earth catches up to a slower-moving outer planet and passes it in its orbit, in the same way that a
faster runner overtakes a slower runner in an outside lane, the outer planet - ANS-exhibits retrograde
motion
An inferior planet is one that is - ANS-closer to the sun than the earth
How did the ancients know the planets were different from the stars? - ANS-They saw that the planets
move with respect to the stars over the course of many nights.
