$200 Rilles and Mares What is a feature due to lunar volcanoes?

$400 Erosion (by the Colorado River) The Grand Canyon is formed by what kind of process?

$600 Two tectonic plates colliding Mountain chains such as the Himalayans are formed due to what process?

$1000 trench What feature is formed in the deep parts of the ocean where dense oceanic plate subducts beneath lighter continental plate

$800 Rift valleys, trenches, mountains, volcanic chains, faults,mid-ocean ridges What are three surface features due to plate tectonics?

$200 Spring The type of tide with the largest tidal variation is?

$400 small Would 1 st quarter moon phase have a large tidal range or a small tidal range?

$600 The moon lacks an atmosphere, wind and water The rate of erosion on the moon is less than Earth because?

$800 Yellowstone and Hawaii Examples of Hot spots on Earth are

$1000 Explain where is the newest material in the Earth’s crust found? In the mid-ocean ridges where plate tectonics constantly extrudes new lava

$200 Jupiter Which planet’s mass is more than the mass of all the other planets put together?

$400 No, the denser planets lie closer to the sun Is this statement true- planetary density increases with increasing distances to the sun? Why or why not?

$600 Venus and the Gas Giants Which planets’ rotations are difficult to determine due to their atmospheres

$800 Which planets have rings around their equator? The Jovian planets

$1000 Terrestrial, Jovian _____________________ are planets that are of denser materials such as iron and silicates. ________________ are less dense and made of gases like the sun.

$200 Impact Theory Which theory currently best explains the moon’s origin?

$400 Accretion The term for the growth of a celestial object by accumulating matter is called?

$600 Spins faster due to angular momentum Once the solar nebula contracts what does it do next?

$800 The terrestrial planets are of heavier elements and smaller, the Jovians are lighter, larger and have more moons and faster rotational periods What are three reasons the planets are split into two groups?

$1000 A nebula collapses, spins faster and flattens into a disk. The center of the disk heats up forming protosun and proto planets. Protoplanets collect material (accrete), their gravity takes over and they become planetesimals. These collide and become planets. Leftover debris became asteroids and comets. Describe the theory of the origin of the solar system.

$200 Between Mars and Jupiter in the asteroid belt Most asteroids are found

$400 Where is the Kuiper belt found Beyond Neptune

$600 From a spacecraft sent to an asteroid What has given us the most detailed look of an asteroid?

$800 A Kuiper belt object, a dwarf planet and a plutoid. What is Pluto considered?

$1000 Describe the orbits of asteroids and Kuiper belt objects Both orbit near the ecliptic plane,Asteroids are closer in between mars and Jupiter while KPO are past Neptune

$200 Jupiter, Saturn, Uranus and Neptune The jovian planets are?

$400 Terrestrial Planets The asteroids are most like________________ ________________ in composition and density.

$600 The process of transfer heat from hotter to cooler levels What is convection?

$800 Most interplanetary debris was swept up during the formation of the solar system The fact that the rate of cratering has died down over time shows that

$1000 Any theory of solar system formation must address what issues? High density of terrestrial vs. Jovian. Why do Jovians have thick atmospheres? Why are asteroids made of primitive materials. Why are comets icy?
