Use the Planet Data Chart in your notes to answer the following questions. Which planet has: the longest period of rotation? the highest density? the lowest density? the highest mass compared to Earth? the smallest diameter? fastest spin on its axis? slowest orbital velocity? the most moons? feels the strongest pull of gravity from the sun? 8. Match the terms with their definitions. orbit of planet around Sun sun-centered solar system spinning of planet on its axis place in planet s orbit where it is closest to Sun earth-centered solar system place in planet s orbit where it is farthest from Sun A. perihelion B. aphelion C. rotation D. revolution E. geocentric F. heliocentric 9. The scientist who described the laws of planetary motion was 1 st law: Planets orbit the sun in shaped paths, with the sun at one focus. During its orbit around the sun, a planet s distance to the sun changes. The point where the planet is closest to the sun is called and the point
where the planet is farthest from the sun is called. 2 nd law: A line from the planet to the sun sweeps through equal areas in equal time. Therefore, a planet s orbital velocity (speed) is (slower/faster) when it is closer to the sun than when it is farther from the sun. 3 rd law: A planet s period of revolution gets (shorter/longer) as its distance from the sun increases. The planet with the shortest period of revolution is, and has the longest period of revolution. 10. Based on Kepler s laws: Label the point on the right as the Sun. Label the point on the ellipse that is closest to the sun (perihelion) and farthest from the sun (aphelion) Show where in its orbit of the Sun a planet would move faster and where it would move slower. An ellipse is described by the property of eccentricity = F/A, where F is the distance between the FOCI and A is the length of the major axis. Measure F and A on the diagram and calculate eccentricity. F = A = eccentricity = 11. is the force that keeps planets in orbit around the sun. The scientist who identified this force was Circle an answer from the choices in parentheses: The force depends on mass and distance: it is (stronger OR weaker) when the masses are bigger and gets (stronger OR weaker) as the distances increases. Planets closer to the Sun feel a (weaker OR stronger) attraction to the Sun than more distant planets. The Sun s gravity is the strongest force in the solar system because the Sun has the largest mass in the solar system. Giant planets have many moons and rings because they have larger masses and stronger gravity than terrestrial planets. As a planet orbits the Sun, its distance from the Sun changes; it moves (faster/slower) when it is closer to the sun, at (perihelion/aphelion).
UNIT 4 Energy Transfer & Earth s Seasons 1. What is the source of energy for Earth s atmosphere? 2. Match each type of energy transfer with its definition and the states of matter in which it occurs. radiation a. movement of substances due to density differences conduction b. energy transfer by waves across space convection c. molecule to molecule energy transfer by direct contact d. most efficient in solids e. most efficient in fluids (liquids and gases) f. no molecules required 3. Match each type of energy transfer with examples of each process. radiation a. ironing a pair of pants conduction b. circulation of heated air in a room convection c. getting a sunburn d. heating food in a microwave e. boiling water in a pot f. frying a pancake 4. Darker surfaces absorb (more/less) energy and reflect (more/less) energy than lighter surfaces. A substance that absorbs more energy will radiate (more/less) energy. Land surfaces absorb energy (faster/slower) than water and cool off (faster/slower). 5. Explain how temperature and density differences in a fluid cause convection. Circle answers. As a substance heats up, its molecules move (faster/slower) and (expand/contract). This causes volume to (increase/decrease) and density to (increase/decrease). The substance (rises/sinks). As the substance cools, the opposite occurs: molecules (faster/slower) and (expand/contract); volume (increases/decreases) and density (increases/decreases). The substance (rises/sinks). Warm air is (more/less) dense than cooler air, so warm air (rises/sinks). 6. Draw and label a convection current. Show where the heat source is, where hotter and colder matter and where more and less dense matter would be, and show which would rise and which would sink.

Identify 2 greenhouse gases: What are 2 ways that carbon dioxide gets into the atmosphere? What are 2 ways that carbon dioxide is removed from the atmosphere?
