E+E U2: Astronomy 1 GRADE A FULLY
ANSWERED QUESTIONS WITH ANSWER
rotation - (correct answer)the spinning (turning) of a celestial body on its axis
SCIENTIFIC IMPORTANCE:
Earth's rotation creates DAY and NIGHT
revolution - (correct answer)the path of a celestial object as it orbits another point in
space (or object)
SCIENTIFIC IMPORTANCE:
Earth's revolution around the Sun and tilted axis create seasonal changes
seasons - (correct answer)created by Earth's TILTED AXIS and REVOLUTION around
the Sun
SCIENTIFIC IMPORTANCE:
SEASONS are caused by differences in the INTENSITY (strength) of sunlight, NOT the
distance from the Sun
latitude - (correct answer)the distance from the equator north or south measured in
degrees
SCIENTIFIC IMPORTANCE:
the EQUATOR receives more direct sunlight (higher intensity) than the POLES
throughout the year (lower intensity)
precession - (correct answer)the change in the direction of Earth's axis over time
