20. What information can astronomers gather about stars using spectroscopy?

📋 Answer Key

1. b) Biosphere

2. c) Heat and pressure

3. b) Convection currents in the mantle

4. Igneous rocks can weather to form sedimentary rocks; sedimentary rocks can be heated/pressurised to form metamorphic rocks; any rock type can melt to form magma that cools into igneous rock.

5. Renewable: solar, wind, water, biomass; Non-renewable: coal, oil, natural gas, uranium

6. b) Along tectonic plate boundaries

7. Magma rises from the mantle due to pressure and heat; erupts when pressure builds up in magma chamber.

8. b) Solar energy from the Sun

9. b) The tilt of Earth's axis

10. c) Water vapour

11. Earth's hemispheres are tilted differently towards the Sun at different times of year due to Earth's axial tilt.

12. Burning fossil fuels, deforestation, industrial processes, agriculture, transport

13. a) Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

14. c) The Moon's gravity

15. b) Gravitational force
