3 Earth s Orbit The motion of one object around another object is called revolution. Earth makes one complete revolution around the un every days. The path an object follows as it moves around another object is an orbit. Earth orbits the un in an almost circular path. Earth s orbit is shown below. Visual Check 2. Describe What is the shape of Earth s orbit around the un? (Circle the correct answer.) a. circle b. near circle c. a straight line The un s Gravitational Pull Earth orbits the un because the un s gravity pulls on Earth. The strength of gravity s pull between two objects depends on the masses of the objects and the distance between them. An object with more mass has a greater pull of gravity than an object with less mass. Likewise, gravity s pull is greater on objects that are closer together. Key Concept Check 3. Identify What produces Earth s revolution around the un? Reading Check 4. Identify In which direction does Earth rotate? Earth s motion without the un s gravitational pull July 4 Earth is farthest from the un. Earth 152 million km Gravitational pull of the un January 3 un 147 million km Earth s Orbit Earth is closest to the un. Earth s orbit around the un, shown above, is like the motion of an object twirled on a string. The string pulls on the object and moves it in a circle. If the string breaks, the object flies off in a straight line. The un s gravity is like the string. Gravity keeps Earth revolving around the un in a nearly circular orbit. If the pull of gravity between the un and Earth stopped suddenly, Earth would fly off into space in a straight line. Earth s Rotation As Earth revolves around the un, it spins. A spinning motion is called rotation. Earth rotates on an imaginary line that runs through its center. The line on which an object rotates is the rotation axis. If you could look down onto Earth s orth Pole, you would see that Earth rotates in a counterclockwise direction, from west to east. One complete rotation of Earth takes about 24 hours. One rotation completes Earth s cycle of day and night. It is daytime on the half of Earth that faces the un. It is nighttime on the half of Earth that faces away from the un. 300 The un-earth-moon ystem Earth s Motion

4 The un s Apparent Motion Each day, the un appears to move across the sky from east to west. It seems as if the un is moving around Earth. In fact, it is Earth s rotation that causes the un s apparent motion. Earth rotates from west to east. This makes the un appear to move from east to west across the sky. The Moon and stars also seem to move from east to west across the sky due to Earth s west-to-east rotation. Earth s west-to-east rotation causes apparent east-to-west motion in the sky. The Tilt of Earth s Rotation Axis Earth s rotation axis is tilted, as shown in the figure below. The tilt of Earth s rotation axis does not change. During one-half of Earth s orbit, the north end of the rotation axis is toward the un. During the other half of Earth s orbit, the north end of the rotation axis is away from the un. Reading Check 5. Describe What causes the un s apparent motion across the sky? Earth s orbit Rotation axis December eptember Earth un Visual Check 6. Identify Between which months is the north end of Earth s rotation axis away from the un? March June Temperature and Latitude As Earth orbits the un, the un shines on the half of Earth that faces the un. unlight carries energy. The more sunlight that reaches a part of Earth s surface, the warmer that part becomes. Because Earth s surface is curved, different parts of Earth s surface get different amounts of the un s energy. Energy Received by a Tilted urface uppose you shine a flashlight onto a flat card. The beam shines in a circle on the card. As you tilt the top of the card away from the beam of light, the light becomes more spread out on the card s surface. The energy that the light beam carries also spreads out more over the card s surface. An area on the surface within the light beam receives less energy when the surface is more tilted relative to the light beam. Reading Check 7. ummarize Why do some parts of Earth s surface get more energy from the un than other parts? Earth s Motion The un-earth-moon ystem 301

5 When the surface is tilted, the light beam is spread out over a larger area. urface is vertical. urface is tilted. The dotted line shows the area covered by the light beam before the surface was tilted. Visual Check 8. Determine Is the light energy more spread out on the vertical or tilted surface? Key Concept Check 9. Cause and Effect Why is Earth warmer at the equator and colder at the poles? Math kills When Earth is 147,000,000 km from the un, how far is Earth from the un in miles? To calculate the distance in miles, multiply the distance in km by the conversion factor miles 147,000,000 km 1 km = 91,100,000 miles 10. Convert Units When Earth is 152,000,000 km from the un, how far is Earth from the un in miles? The Tilt of Earth s Curved urface Instead of being flat and vertical like the card shown above on the left, Earth s surface is curved and tilted, somewhat like the card on the right. Earth s surface becomes more tilted as you move away from the equator and toward the poles. As a result, regions of Earth near the poles receive less energy than areas near the equator. This is why Earth is warmer at the equator and colder at the poles. easons You might think that summer happens when Earth is closest to the un. However, seasonal changes do not depend on Earth s distance from the un. In fact, Earth is closest to the un in January! The tilt of Earth s rotation axis and Earth s motion around the un cause the seasons to change. pring and ummer in the orthern Hemisphere During one-half of Earth s orbit, the north end of the rotation axis is toward the un. Then, the northern hemisphere receives more energy from the un than the southern hemisphere does. ee the figure on the right on the next page. Temperatures are higher in the northern hemisphere and lower in the southern hemisphere. Daylight hours last longer in the northern hemisphere. ights last longer in the southern hemisphere. It is spring and summer in the northern hemisphere and fall and winter in the southern hemisphere. Fall and Winter in the orthern Hemisphere During the other half of Earth s orbit, the north end of the rotation axis is away from the un, as shown in the left figure on the next page. Then, the northern hemisphere receives less energy from the un than the southern hemisphere does. Temperatures are cooler in the northern hemisphere and warmer in the southern hemisphere. It is fall and winter in the northern hemisphere. At the same time, spring and summer occur in the southern hemisphere. 302 The un-earth-moon ystem Earth s Motion

But the amount that Earth s rotation axis is toward or away from the un changes. This causes the yearly cycle of the seasons. There are four days each year when the direction of Earth s axis is special relative to the un. A solstice is a day when Earth s rotation axis is the most toward or away from the un. An equinox is a day when Earth s rotation axis is leaning along Earth s orbit, neither toward or away from the un. March Equinox to June olstice The north end of the rotation axis slowly points more and more toward the un. As a result, the northern hemisphere slowly receives more solar energy. pring takes place in the northern hemisphere. June olstice to eptember Equinox The north end of the rotation axis still points toward the un but does so less and less. The northern hemisphere starts to receive less solar energy. This is summer in the northern hemisphere. eptember Equinox to December olstice The north end of the rotation axis points more and more away from the un. The northern hemisphere receives less and less solar energy. Fall takes place in the northern hemisphere. December olstice to March Equinox The north end of the rotation axis still points away from the un but does so less and less. As a result, the northern hemisphere starts to receive more solar energy. This is winter in the northern hemisphere. Earth s seasonal cycle is summarized in the table on the next page. Visual Check 11.
