Space Exam Style Questions 1 1. The table below shows information about several planets. Time for one orbit Average surface Distance from Sun Planet (Earth years) temperature (°C) (million km) Mars 687 days -82 to 0 228 Jupiter 12 years -150 778 Saturn 29 years -170 1427 How does the surface temperature of the planets relate to their distance from the Sun? Why do you think the temperature changes in this way? Uranus is 2870 million km away from the Sun. Give an estimate of its surface temperature. 2. The diagram below shows the planets in the solar system. Label the planets. It takes Jupiter much longer than Mars to complete one orbit of the Sun. Give 2 reasons for this. 1. 2. Space Exam Style Questions 2 1. The diagram shows the position of the Sun, Moon and Earth during a lunar eclipse. Explain how a lunar eclipse occurs. 2. A group of students are discussing meteors, meteorites and comets. However, they have confused the terms. Can you correct their descriptions? Student A Student B Student C “A meteor is just dust “Comets are any stony “Meteorites are pieces particles frozen in or metallic debris that of rocks or dust that ice, that orbit has fallen to Earth from streak through the sky the Sun.” outer space.” at night.” Student A is describing a Student B is describing a Student C is describing a Space Key Revision Facts The International Space Station (ISS) is an example of an artificial satellite. The Moon is an example of a natural satellite. A comet is frozen dust particles that are orbiting the Sun. A meteor is the name given to pieces of dust and rock travelling through the sky. The planets in the solar system are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. A day is 24 hours and is the time it takes for the Earth to rotate completely on its axis. A year is 365 ¼ days and is the time it takes the Earth to orbit the Sun. Seasons occur because of the tilt of the Earth on its axis and its position in orbiting the Sun. Solar eclipse: when the moon comes between the Sun and Earth. Lunar eclipse: when the Earth comes between the Sun and Moon. The moon takes 27 days and 7 hours to orbit the Earth. As the Moon moves around the Earth, its shape appears to change. This is known as phases of the Moon. new moon waxing crescent first quarter waxing gibbous full moon waning gibbous last quarter waning crescent Space Test Yourself 1 Match and Draw Match the key word with its definition. meteor huge snowballs that orbit the Sun meteorite a collection of stars bits of dust and rock that move comets through the sky constellations any meteor that lands on Earth Planets Word Search Find the planets of the solar system in the word search and then put them in order, starting with the planet nearest the Sun first. r s z t f m x o l n s a t v m t u g f u o b p m u r j d j x e n r h n g q z n v h u u w n Mercury w a t m h m f e h z e p t d y Venus h r u e t a v y q s i g w a c a u p r l r y e h t y u r d s Earth v c j c k s f v e n u t p e n Mars s y d u m p a r u d z z x c i Jupiter i q m r r g o e p w x a t h a l l t y p h w n s c x o o y k Saturn e m c c s l n m a u i t e e w Uranus k s d m g j u u s g o e e c i x w n c a p m t b x w c d v u Neptune p f e a r t h j o k i h g g l m p y k n z m b e g d v o f k How Long?

As far as we know, Earth is the only planet that contains and supports life. What factors are required to support life?
