5. 5The units to measure distances in the Universe are: [blank_start]light year[blank_end], [blank_start]parsec[blank_end] and [blank_start]astronomical units[blank_end]

   1. Alight year
   2. Bparsec
   3. Castronomical units
6. 6In the [blank_start]Geocentric[blank_end] model, the Earth is in the centre of the Universe. In the [blank_start]Heliocentric[blank_end] model, the stars are fixed on a dome that doesn´t move.

   2. Belliptical
   3. Cspherical
   4. Dbarred spiral
   5. Eirregular
8. 8The phases of the Moon are: [blank_start]new moon[blank_end], [blank_start]first quarter[blank_end], [blank_start]full moon[blank_end] and [blank_start]last quarter[blank_end]

   1. Anew moon
   2. Bfirst quarter
   3. Cfull moon
   4. Dlast quarter
9. 9Why we see always the same side of the Monn? because the Moon [blank_start]lasts to rotate a revolt 28 days[blank_end]

   1. Alasts to rotate a revolt 28 days
10. 10The Solar System is located in [blank_start]the Orion Arm[blank_end]
