- 5. mountains – mountains formed when two tectonic plates collide and rock layers are forced upward into folds
- 6. – the world's highest fold mountain range, formed by the collision of the Indian and Eurasian plates
- 9. – the wearing away and removal of rock or soil by water, wind or ice
- 12. plates – large sections of the Earth's crust that move slowly and can collide to form fold mountains
- 15. seeker – a person who flees to another country and applies to stay there because they fear for their safety
- 17. – moving into a new country to settle there permanently
- 19. – an upward fold in rock layers shaped like an arch or hill
- 21. rock – rock formed from layers of compressed sediment over millions of years, e.g. limestone or sandstone
- 23. – describes rock that does not allow water to pass through it, e.g. granite
- 25. – the process by which rainwater washes minerals downward through the soil
- 27. – decomposed organic matter in soil that provides nutrients for plants
- 28. rate – the number of deaths per 1,000 people per year

Down
- 1. migrant – a person who moves to another country in search of better work or living conditions
- 2. density – the number of people living per square kilometre in an area
- 4. – a major fold mountain range in Europe, formed by the collision of the African and Eurasian plates
- 7. – the thin layer of material on the Earth's surface in which plants grow
- 8. zone – the area where two tectonic plates meet and push against each other
- 10. – the breaking down of rock into smaller particles that eventually become part of soil
- 11. – the layer below the topsoil, containing less organic matter and more minerals
- 13. – the upper layer of soil, rich in humus and most suitable for plant growth
- 14. – the growth in the proportion of people living in towns and cities
- 16. rock – rock formed when magma cools and solidifies, e.g. granite or basalt
- 18. – describes rock that allows water to pass through it, e.g. limestone
- 20. factor – a reason that drives people to leave their home area, e.g. war, poverty or famine
- 22. rock – rock that has been changed by extreme heat and pressure, e.g. marble or schist
- 24. rate – the number of live births per 1,000 people per year
- 26. – leaving your home country to live permanently in another country
- 29. increase – when the birth rate is higher than the death rate, causing population to grow
- 30. to urban migration – the movement of people from the countryside into towns and cities
- 31. – a downward fold in rock layers shaped like a valley
