REVIEW SHEET FOR ASTRONOMY C.U.B.A.
CHAPTER 19: EARTH, MOON AND SUN
SECTION 1: Earth in Space
19-1 PowerPoint: Link on Mr. Price’s Webpage
-Describe the difference between rotation and revolution and how long it takes for the
Earth to do both. (P-H Page # 637)
Rotation: Spinning of Earth on its axis – Gives us day and night. (One Rotation = One Day)
Revolution: The amount of time it takes the Earth to orbit the sun. (One Revolution = One Year)
-Describe and explain what causes the seasons, dates at which we have equinoxes and
solstices and the position of the Earth’s axis in each season. (P-H Pages # 640-643)
The Earth is tilted on its axis as it revolves around the sun. Because the Earth is a sphere, the sunlight hitting some parts of the Earth is more concentrated than the sunlight hitting other parts of the Earth.

SECTION 2: Phases, Eclipses and Tides
-Recognize the 8 phases of the moon – what they look like and where they are in
relationto the sun. Explain what causes phases. (P-H Pages # 647-649)
The lunar cycle takes about 29 days.
-Describe and explain the position of the Earth, moon and sun for solar and lunar
eclipses and when theyoccur.(P-H Pages # 650 & 651)
-Describe the difference between spring and neap tides and when they occur. Explain
what a regular tide is and how often they occur and why.(P-H Page # 436 & 437, 654)
Spring and Neap Tides:
SECTION 4: Earth’s Moon
19-4 PowerPoint: Link on Mr. Price’s Webpage
-Describe the basic structure and origin of the moon and its features. (P-H Pages # 659-664)
Why don’t we ever see the far side of the moon?
What is the accepted theory as to how the moon formed?
What are the moon’s surface and atmospheric features?
CHAPTER 20: THE SOLAR SYSTEM
SECTION 1: Observing the Solar System
20-1 PowerPoint: Link on Mr. Price’s Webpage
-Know the two factors that keep the planets in orbit.(P-H Pages # 673 & 674)
Inertia: Explains the movement of the planets around the sun. Objects in motion remain in motion until acted upon by an outside force. The planets continue to move around the sun because they always have since the time of their formation.
Gravity: Explains why the planets stay in orbit around the sun rather than flying off into space.
SECTION 2: The Sun

SECTION 5: Comets, Asteroids and Meteors
20-5 PowerPoint: Link on Mr. Price’s Webpage
-Know the definitions of each.(P-H Pages # 700-703)
Descriptions of Different Celestial Objects
Celestial Object Name / DescriptionAsteroid / An asteroid is an irregularly shaped celestial object made up of rock or metal. They are smaller than planets and have irregular shapes rather than spherical shapes.
Comet / A comet is a celestial object made up of ice, rock, and dust that has a very long orbit around the sun. As they move closer to the sun, they develop tails. Sunlight reflects off the tail making it visible.
Meteoroid / A meteoroid is a very small, rocky celestial object. Meteoroids are smaller than asteroids. They are pieces of asteroids, moons, planets, or debris from comets.
Meteor / A meteor is a flash of light in the sky that occurs as a meteoroid burns up in the atmosphere. Meteors are also known as shooting stars.
Meteorite / A meteorite is a small piece of rock from space that lands on Earth. Meteorites are meteoroids that do not burn up completely.
