- 33. The boundary between terrestrial and jovian planets separating condensation.
- 34. Many meteors that come from the same point in the night sky and are associated with the orbits of known comets.
- 38. The largest volcano in the solar system that is on Mars.
- 39. All Jovian planets have them, but Saturn is the most impressive.
- 40. Small bodies (comets or asteroids) that are large enough to be round.
- 41. The kinds of volcanoes seen on other planets in the Solar System that are flat and broad.

Down
- 1. Small bodies formed from condensation and accretion of gas/dust in the solar nebula.
- 2. A meteor that lands on the surface of the Earth.
- 3. The part of the solar atmosphere that produces color.
- 4. Theory that planets condense from an enormous cloud of H and He gas called the solar nebula around the forming Sun.
