d) month
e) 12 months

2) The half of the Earth which faces the Sun is in:

6) The Solar System model replaced an ancient Earth-centred model. In the old model early observers thought the Sun:  

a) orbited the Moon
b) orbited the Earth
c) orbited the comets
d) orbited the Sun

7) The old Earth centred model was replaced when astronomers could not explain:  

a) the motion of the stars across the night time sky
b) the motion of the planets across the night time sky
c) the motion of comets across the night time sky
d) the orbiting of the constellations

8) The stars in the night sky stay in fixed:  

a) patterns
b) locations
c) orbits
d) places

9) These fixed patterns are called:  

a) eclipses
b) black holes
c) constellations

d) the milky way
e) tides

11) To recognise that planets are different to stars - the planets seem to move very slowly across the background of the:  

a) tides
b) clouds
c) moon
d) constellations
e) orbit

12) The planets:  

a) emit radar pulses
b) emit sound waves
c) emit microwaves
d) do not give out their own light
e) emit infra-red radiation

13) Like the Earth the planets move in:  

a) orbits around the Sun
b) constellations
c) loop the loops
d) gravity wells
e) galaxies

14) We can see planets because they:  

a) reflect heat from the sun
b) reflect light from the Sun
c) reflect sound from the sun
d) reflect ultra-violet from the sun
e) reflect microwaves from the sun

15) Where we see the planets against the background of the stars depends on exactly:  

a) how far apart they are
b) how much light they are emitting
c) how much light they reflect
d) where they and the Earth are in their orbits round the Sun
