questions with answers || ||
Explain the physical reason why we on Earth experience day and night. -
|| || || || || || || || || || || || ||
CORRECT ANSWERS ✔✔Earth rotates about an axis of rotation once every
|| || || || || || || || || || ||
24 hours.
||
What is a light year? - CORRECT ANSWERS ✔✔The distance light travels in
|| || || || || || || || || || || || ||
one year.
||
Approximately how far is the Sun from Earth? - CORRECT ANSWERS ✔✔1 || || || || || || || || || || || ||
AU, 150 million km, 93 million miles, 8 light minutes
|| || || || || || || || ||
About how far is the closest star to the Sun? - CORRECT ANSWERS ✔✔4
|| || || || || || || || || || || || || ||
light years ||
Explain why Earth has seasons. - CORRECT ANSWERS ✔✔Earth's axis is
|| || || || || || || || || || ||
tilted with respect to the orbital plane. When the northern hemisphere is
|| || || || || || || || || || || ||
tilted toward the Sun it is summer, even though we are further from the Sun.
|| || || || || || || || || || || || || ||
Objects in the sky rise in the east and set in the west because Earth rotates
|| || || || || || || || || || || || || || || ||
from ___ to ___ about its axis. - CORRECT ANSWERS ✔✔West to East
|| || || || || || || || || || || ||
, What two main factors dictate how bright a star is as seen from Earth? -
|| || || || || || || || || || || || || || ||
CORRECT ANSWERS ✔✔How intrinsically bright it is and how far away it
|| || || || || || || || || || || ||
is.
What are commonly recognized star patterns known as? - CORRECT
|| || || || || || || || || ||
ANSWERS ✔✔Constellations ||
What is significant about the Zodiac in the sky? - CORRECT ANSWERS
|| || || || || || || || || || || ||
✔✔They lie along the plane of the ecliptic (the plane of the solar system)
|| || || || || || || || || || || || ||
Explain why stars appear at the same locations on the celestial sphere while
|| || || || || || || || || || || || ||
the Sun, Moon, and planets move during the course of the year. - CORRECT
|| || || || || || || || || || || || || ||
ANSWERS ✔✔The stars are so incredibly far away that even though they are
|| || || || || || || || || || || || ||
moving, the motion is hardly recognizable from Earth .
|| || || || || || || ||
List the 7 major types of electromagnetic radiation (light) from highest to
|| || || || || || || || || || || ||
lowest energy. - CORRECT ANSWERS ✔✔Gamma, x-ray, ultra violet, visible,
|| || || || || || || || || ||
infra red, microwave, radiowave
|| || ||
What is the light carrying particle known as? - CORRECT ANSWERS
|| || || || || || || || || || ||
✔✔Photon
A fundamental limitation of a telescope's ability to resolve images, based on
|| || || || || || || || || || || ||
the wave-like nature of light is known as _____. - CORRECT ANSWERS
