Chapter 9 Review

The time required for a planet to rotate on its axis one complete time is known as what? day

Periodic rise and fall of the water level in the oceans and other large bodies of water are known as what? Tides

When the shadow of one celestial (in space) body falls upon another celestial body it is called an: Eclipse

The path that a body follows as it travels around another body in space is known as what? Orbit

The two days per year where neither pole is tilted more toward the sun are known as what? Equinoxes

The movement of a body traveling around another body in space is called: revolution

Who was the German astronomer that developed the laws of planetary motion ? Johannes Kepler

The scientific law that states that planets move around the sun in elliptical paths is called: Kepler’s First Law of Planetary Motion

“The force of gravity depends on the product of the masses (m x m), divided by the square of the distance between them (d 2 ),” is known as what scientific law? Newton’s Law of Universal Gravitation

What is Kepler’s Second Law of Planetary Motion planets move faster the closer they are to the sun

What force causes the tides to rise and fall each day? Gravitational pull of the Moon

The two days every year where there are exactly the same number of daylight hours as dark are known as what? Equinoxes

“ The time it takes a planet to orbit the sun is directly proportional to the distance the planet is from the sun” is known as what scientific law? Kepler’s Third Law of Planetary Motion

The change in sunlit area of one celestial body (in our case, the moon) as seen from another celestial body is called what? phases

The two days per year where the axis of the Earth leans towards (or away from) the sun the most. Solstices

If the mass of the earth were doubled, how would that affect your weight? Your weight would double

The difference in levels of ocean water between high and low tides is known as what? Tidal Range

What kind of eclipse happens when the shadow of the moon falls on the Earth? Solar Eclipse

When moon phases are waning, the sunlit part of the moon is in the process of getting ______________. smaller

The two days per year where we have either the most amount of sunlight or the least amount of sunlight are called what? Solstices

What kind of eclipse happens when sections of the sunlit moon are blocked out by the shadow of the earth Lunar Eclipse

Name a season of the year when an equinox might occur. Spring or Fall

Tides of increased tidal range which occur when the SUN-EARTH-MOON are in a straight line are known as what? Spring Tides

When moon phases are __________, the sunlit part of the moon is in the process of getting larger Waxing

Tides of decreased tidal range which occur when the SUN-EARTH-MOON form a 90 0 angle are known as what? Neap Tides

Because the time required for one rotation of the Earth and one revolution of the moon are ___________, we always see the same side of the moon. equal

Name a season of the year when a solstice might occur. Winter or summer

What fact about the Earth’s axis causes there to be changing seasons in many places on the earth? 23.5 0 tilt

If the distance between two bodies in space increases, what happens to the force of gravity between them? decreases

When the north pole is pointing towards the sun, what season is it in California? Summer

Toss Up Questions

What kind of tide has the highest low tide? Neap tides

Why don’t we see lunar and solar eclipses every month? The orbit of the moon is tilted 5 0 off that of the Earth

What kind of tide has the highest high tide? Spring tides

A closed curve in which the sum of the distances from the edge of the curve to two points inside the curve are always equal is known as what? Ellipse

What kind of tide has the lowest high tide? Neap tides

What kind of tide has the lowest low tide? Spring tides

What kind of eclipse occurs when most of the sun is blocked out by the moon but the moon appears to not be large enough to block out the entire sun? Annular Solar Eclipse
