Study Guide
Answer all questions on your own paper. Explain in detail.
1. Which planets would have a greater gravitational pull from the sun? List them and
explain why.
Mercury, Venus, Earth, Mars. They are closer to the Sun than Jupiter.
2. Which planets would have a weaker gravitational pull from the sun? List them and
explain why.
Neptune, Uranus, Jupiter, Saturn. The farther a planet is from the Sun,
the weaker the gravitational force between them
3. What are some things astronauts would need to survive on another planet?
Air (oxygen), food, water
4. What is a comet?
A celestial object consisting of a nucleus of ice and dust and, when near the sun, a
“tail” of gas and dust particles pointing away from the sun
5. What is a meteor?
6. What is an asteroid?
rocky body orbiting sun. Large numbers, ranging in size from nearly 600 miles
(1,000 km) across to dust particles, found (in the asteroid belt ) especially
between the orbits of Mars and Jupiter.
7. Explain how the planets stay in orbit around the sun.
Inertia keeps them moving forward, the suns gravitational pull, pulls them towards
the sun. The combination of the two makes them orbit around the Sun.
8. Explain how mass and gravitational pull related?
Greater the mass the stronger the gravitational pull
9. What is Newton’s Law of Universal Gravitation and how does it help explain why
moons stay in orbit around their planets?
Newton’s Law of Universal Gravitation states that gravity exists between any two
objects. There is gravity between a moon and its planet.
10. How has the Hubble Telescope been the most useful to astronomers?
Useful in studying the universe. NASA's Hubble Space Telescope Located high
above Earth's obscuring atmosphere, the telescope has provided the clearest
views of the universe.
11. List the planets from the sun out in order.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
12. What 2 forces work together to keep the planets in orbit around the sun?
Gravity and Inertia
13. Where is the asteroid belt located?
Between Mars and Jupiter
14. Explain how a planet could be “eaten” by a star?
The force of gravity of the star was greater than the forward motion of the planet
15. Know the names of the 7 major tectonic plates and where they are located on a
map.
16. What land feature is created when an oceanic plate converges with a
continental plate?
Oceanic and continental plate collisions result in mountain and volcano formation.
Mountains are formed as the overriding continental plate gets lifted up over the
oceanic plate.
17. Draw and explain what happens at a transform boundary.
two plates slide past one another. earthquakes.
18. Explain why Earth has a magnetic field.
The Earth has a magnetic field because the Earth’s core is solid and is made of
Iron.
19.List and describe the layers of Earth in order from the crust in.
Crust, Lithosphere, Asthenosphere, Mantle, Outer Core, Inner Core
20. What is the impact of current and future space exploration?
Examples: To help humans reach an asteroid and Mars. These new space
technologies will spawn new knowledge and capabilities to sustain our future
missions.
