Earth’s SeasonsThe Earth's seasons are not caused by the differences in the distance from the Sun throughout the year (these differences are extremely small). The seasons are the result of the tilt of the Earth's axis.

Summer is warmer than winter (in each hemisphere) because the Sun's rays hit the Earth at a more direct angle during summer than during winter and also because the days are much longer than the nights during the summer. During the winter, the Sun's rays hit the Earth at an extreme angle, and the days are very short. These effects are due to the tilt of the Earth's axis.

SolsticeThe solstices are days when the Sun reaches its farthest northern and southern declinations. The winter solstice occurs on December 21 or 22 and marks the beginning of winter (this is the shortest day of the year). The summer solstice occurs on June 21 and marks the beginning of summer (this is the longest day of the year).

EquinoxEquinoxes are days in which day and night are of equal duration. The two yearly equinoxes occur when the Sun crosses the celestial equator. The Spring equinox occurs in late March (this is the beginning of spring in the Northern Hemisphere and the beginning of fall in the Southern Hemisphere); the autumn equinox occurs in late September (this is the beginning of fall in the Northern Hemisphere and the beginning of spring in the Southern Hemisphere).

QuestionSummer occurs on Earth in the northern hemisphere when:

(a) the northern hemisphere is tilted away from the Sun

(b) the northern hemisphere is tilted towards the Sun

(c) the Earth is revolving closest to the Sun(d) none of these are true

Answer

• (b) the northern hemisphere is tilted towards the Sun

QuestionTrue or False: The equinoxes occur during Fall and Spring?

(a) True(b) False

Answer

(a) True

QuestionWhat is the cause of Earth’s seasons?

(a) the distance of Earth from the Sun(b) the position of the moon(c) Earth’s axial tilt(d) Earth’s orbit

Answer

(c) Earth’s axial tilt

QuestionWhich has more daylight hours in the northern hemisphere?

(a)March 20(b) June 20(c) September 21(d) December21

Answer(b) June 20

Our MoonDuring the waning crescent moon phase, we see a small sliver of light on the ______________ side of the moon.

(a) right(b) left

Answer

(b) left

QuestionWhich phase of the moon occurs directly AFTER the new moon?

(a) waxing crescent(b) waning crescent(c) waxing gibbous(d) waning gibbous

Answer(a) waxing crescent

Did You Know……?We only see one side of the moon. It turns out that the speed at which the Moon rotates has led to this particular phenomenon. Millions of years ago, the Moon spun at a much faster pace than it does now. However, the gravitational influence of the Earth has gradually acted upon the Moon to slow its rotation down. The Moon’s rotational period now matches its revolution – about 29.5 days – and it is now "locked in" to this period.

QuestionWhy do we only see one side of the moon? (a) the Earth’s and moon’s revolution times are

the same(b) the Earth’s rotation and revolution times are

the same(c) the moon’s rotation and revolution times are the same(d) the Earth’s and moon’s rotation times are the same

Answer(c) the moon’s rotation and revolution times are the same

NASA finds “DNA Nebula”

• NASA recently found a nebula in the center of our galaxy that is shaped like a strand of DNA.

• “Nobody has ever seen anything like it before in the cosmic realm," said the study's lead author Mark Morris of UCLA. "Most nebulae are formless conglomerations of dust and gas-space weather.”

The Celestial Sphere

An imaginary sphereof which the observeris the center and on which all celestialobjects are considered to lie.

ZenithThe point on the celestial sphere that is directly

above the observer.

Ecliptic• The ecliptic is the apparent path of the Sun on

the celestial sphere as seen from the Earth.

Celestial Meridian A great circle on the celestial sphere passing

through the celestial poles and an observer's zenith. An observer's celestial meridian is not a fixed reference on the celestial sphere but rather changes with the observer's location on Earth.

Question What is the ecliptic?• (a) pattern of solar eclipses• (b) path of the sun across the sky as viewed

from Earth• (c) pattern of lunar eclipses• (d) when Venus passes in front of the Sun

Answer (b) path of the sun across the sky as viewed

from Earth

Question Which is true about the celestial zenith?• (a) It’s the point on the celestial sphere directly

above the observer• (b) It’s the point on the celestial sphere around

the equator• (c) It’s the point on the celestial sphere around

the horizon• (d) It’s the point on the celestial sphere on the

opposite side of the earth from the observer

Answer• (a) It’s the point on the celestial sphere

directly above the observer

Question The __________________ is the point in the

sky about which all stars seen in the northern hemisphere seem to rotate.

• (a) celestial north pole• (b) celestial south pole• (c) zenith• (d) celestial meridian

Answer• (a) celestial north pole
