| lunar phase in which no reflected light is visible from Earth | NEW MOON |
| the cause of seasons on Earth | EARTH'S AXIS TILT |
| lunar phase associated with a solar eclipse | NEW MOON |
| lunar phase(s) associate with neap tides | 1ST & 3RD QUARTER |
| longest day/date in the northern hemisphere | SUMMER SOLSTICE; JUN 21(ish) |
| the changing relative positions of the Earth, Moon & Sun produce lunar __ | PHASES |
| On the winter solstice, the north pole is tilted away from the Sun, so the northern hemisphere receives the __ amount of solar energy. | LEAST |
| If a planet has no axis tilt -- a 0 degree tilt means the planet has __ . | NO SEASONS |
| number of seasons on Earth | FOUR |
| amount of time required for Earth to complete one revolution | ONE YEAR (365.25 DAYS) |
| amount of time required for the Moon to complete one revolution | 28 DAYS (1 MONTH) |
| amount of time to go from the summer solstice to the winter solstice | 6 MONTHS |
| amount of time to go from new moon to full moon | 2 WEEKS |
| amount of time to go from 1st quarter to new moon | 3 WEEKS |
| amount of time required for Earth to complete one rotation | 24 HOURS |
| amount of time required for the Moon to complete one rotation | 28 DAYS (1 MONTH) |
| amount of time to go from vernal equinox to autumnal equinox | 6 MONTHS |
| phase associated with a lunar eclipse | FULL MOON |
| On which day(s) is NEITHER pole tilted towards the Sun? | EQUINOXES (VERNAL EQUINOX; AUTUMNAL EQUINOX) |
| inertia + gravity = __ | ORBIT |
| 1 week after a full moon = | 3RD QUARTER |
| If a new moon occurs on July 8th, when does the next 1st quarter moon appear? | JULY 15 |
| If a waxing gibbous moon occurs on November 10th, when does the next waning crescent moon appear? | NOVEMBER 24 |
| lunar phases associated with spring tides | NEW MOON & FULL MOON |
| The north pole is tilted most directly towards the Sun on which day/date? | SUMMER SOLSTICE; JUN 21(ish) |
| 12 hours of daylight & 12 hours of night happen on __ | VERNAL EQUINOX & AUTUMNAL EQUINOX |
| If the northern hemisphere is experiencing springtime, the southern hemisphere is having __. | FALL |
| The north pole is tilted most towards the Sun during which season in the southern hemisphere? | WINTER |
| If the Moon is MOSTLY LIGHT, the phase is __. | GIBBOUS |
| phase that is MOSTLY DARK on the RIGHT | WANING CRESCENT |
| phase that is MOSTLY LIGHT on the RIGHT | WAXING GIBBOUS |
| If the Moon is MOSTLY DARK, the phase is __. | CRESCENT |
| phase that is dark on the left half & light on the right half | 1ST QUARTER |
| phase between full moon & 3rd quarter | WANING GIBBOUS |
| As the Earth moves from the winter solstice to the summer solstice, the days in the northern hemisphere are __ (choose one: GETTING LONGER, GETTING SHORTER, NOT CHANGING) | GETTING LONGER |
| lunar phases change as the Moon __ | REVOLVES |
| When the Moon, Earth & Sun are lined up in that order, which phase occurs? | FULL MOON |
| During a solar eclipse, the __ casts a shadow on the Earth. | MOON |
| At any given moment, how much of the Moon's surface reflects the light of the Sun? | HALF |
| We never see the far side of the Earth because the Moon's period of rotation & period of revolution are __ | EQUAL |
| date of the vernal equinox | MAR 21 |
| date of the shortest day of the year | DEC 21 |
| If the Earth's gravitational pull disappeared, what would happen to the Moon? | IT WOULD FLY OFF INTO SPACE IN A STRAIGHT LINE (and hit Mr. Christman in the forehead, right??) |
| Which season is it in the southern hemisphere when the north pole is tilted away from the Sun? | SUMMER (winter in the northern hemisphere) |
| Why are total solar eclipses so rare? | MOON'S ORBIT IS TILTED 5 DEGREES SO THE EARTH, MOON & SUN RARELY LINE UP ON THE SAME PLANE |
| When a total solar eclipse occurs, why can't everyone on the daytime side of Earth see the eclipse? | THE DARKEST PART OF THE MOON'S SHADOW (UMBRA) IS VERY SMALL |
| During a total lunar eclipse, how much of the Moon's surface is in the darkest part of Earth's shadow (the umbra)? | ALL OF IT! (the Earth's umbra is larger than the Moon) |
| If the Moon's forward motion were to stop, what would happen to the Moon? | IT WOULD FALL INTO THE EARTH |
| Earth's axis tilt = __ | 23.5 DEGREES |
| How does the Moon act as climate regulator for Earth? | THE MOON KEEPS EARTH FROM WOBBLING - MAINTAINS THE 23.5 DEGREE AXIS TILT |
| How old is the solar system? | ABOUT 4.6 BILLION YEARS |
| When did the Earth form? | ABOUT 4.6 BILLION YEARS AGO |
| Everything in the solar system revolves around the Sun except __. | MOONS |
| each season lasts __ months | 3 |
| Why does Earth's axis tilt create seasonal changes? | THE AMOUNT OF SOLAR ENERGY AN AREA RECEIVES CHANGES (MORE DIRECT, LESS DIRECT) THROUGHOUT THE YEAR |
| When the Earth moves into the Moon's shadow, a __ __ occurs. | SOLAR ECLIPSE |
| Define ROTATION. | SPINNING OF AN OBJECT ON ITS AXIS |
| How are REVOLUTION and ORBIT related? | REVOLUTION IS THE MOVEMENT OF AN OBJECT AROUND ANOTHER; ORBIT IS THE PATH THE OBJECT FOLLOWS AS IT REVOLVES |
| Earth's constant axis tilt causes the positions of __ __ to change relative to the Sun. | THE POLES |
| Changes to the positions of the poles in comparison to the Sun affects the ___ and ___ of sunlight to a region. | NUMBER OF HOURS and DIRECTNESS (or ANGLE); also correct: QUANTITY and QUALITY |
| Seasons are directly caused by __. | CHANGES IN THE AMOUNT & DIRECTNESS OF SUNLIGHT |
| Changes in the amount & directness of sunlight are directly caused by __. | THE POSITIONS OF THE POLES RELATIVE TO THE SUN |
| The positions of the poles relative to the Sun are directly caused by __. | EARTH'S AXIS TILT |
| How much of the light reflected by the moon is visible on Earth during a new moon phase? | NONE OF IT |
| How much of the light reflected by the moon is visible on Earth during a 3rd quarter phase? | HALF OF IT |
| How much of the light reflected by the moon is visible on Earth during the phase associated with a lunar eclipse? | ALL OF IT |
