Which direction does almost everything in the solar system spin? COUNTER-CLOCKWISE
How much time for 1 full rotation of the earth? 24 HOURS (1 DAY)
How much time for 1 full rotation of the moon? 1 MONTH
What is the average distance from the earth to the sun? 1 AU, 93 MILLION MILES
Compare perihelion and aphelion for earth’s orbit PERIHELION IS CLOSER (91.5 MILLION MILES), APHELION IS FARTHER AWAY (94.5 MILLION MILES)
How much time does it take for light to leave the sun and reach the earth? 8 SECONDS
How much time does it take for a spaceship to reach the moon 1-4 DAYS DEPENDING ON SPEED
What is the diameter of the earth? ABOUT 8000 MILES

What is the diameter of the moon? ABOUT 2,000 MILES
How many moons could fit across the earth? 4
Which is faster, the rotation (spin) of the earth or the revolution (orbit) of the earth? REVOLUTION IS MUCH FASTER
Explain why seasons occur WHICHEVER HEMISPHERE OF THE EARTH IS TILTED TOWARDS THE SUN GETS MORE INTENSE LIGHT AND WILL HAVE SUMMER. THE OPPOSITE HEMISPHERE WILL HAVE LESS DIRECT SUNLIGHT AND HAVE WINTER
What angle is earth tilted at? 23.5 DEGREES

Describe the orientation of the sun, earth, and moon that leads to a lunar eclipse SUN THEN EARTH, THEN MOON. SHADOW OF EARTH COVERS MOON
Describe the orientation of the sun, earth, and moon that leads to a SOLAR eclipse SUN THEN MOON THEN EARTH. SHADOW OF THE MOON DARKENS PARTS OF THE EARTH.
Which is more common, solar or lunar eclipses? Explain why. LUNAR ECLIPSES ARE MORE COMMON BECAUSE THE EARTH’S SHADOW IS LARGER
How many high tides occur in a given area each day? 2 HIGH TIDES
How many hours between high and low tide? 6 HOURS
Explain what causes high and low tides. THE GRAVITY FROM THE MOON PULLS WATER SLIGHTLY CLOSER TO IT FOR THE FIRST HIGH TIDE. ON THE OPPOSITE SIDE OF THE EARTH, THERE IS LESS GRAVITY FROM THE MOON.
