Across
- 2. - Solid, dense layer about 1400km diameter, composed of iron and nickel at 5500°C
- 3. - Small tributary valleys left 'hanging' above the main valley floor after glacial erosion
- 4. Ice - True ice formed after 20 years of compression, blue in appearance and smooth to touch
- 8. - Past interlocking river valley spurs cut off by glacial action, forming cliff-like edges
- 13. - Knife-edge, steep-sided ridge formed when two glaciers flow back-to-back
- 16. Sheet - Giant glaciers covering vast areas
- 17. - Providing services to individuals or businesses
- 18. - Gently sloping volcano with runny lava and gentle eruptions, formed at divergent boundaries
- 20. - Long, thin lake formed where glaciers carved deeper troughs in softer rock
- 22. - The process where new snow falls on mountains at high altitude each winter
- 29. - Adaptation of global products to fit local cultures, tastes or laws
- 31. - Three-sided, pointed mountain peak formed when three or more glaciers carve away at a mountain top
- 33. - Semi-molten metal layer about 2100km thick at 5000-5500°C
- 34. - Where two plates of similar density meet, forming fold mountains
- 37. - Effects caused by primary hazards (tsunamis, landslides, fires, lahars)
- 38. - Plate boundary where plates move apart, creating new crust
- 39. - Point on Earth's surface directly above where an earthquake starts
- 40. - Company operating in multiple countries
- 41. - Manufacturing and processing raw materials into products
Down
- 1. - Direct results of earthquake or eruption (ground shaking, lava flow)
- 5. - Steep-sided volcano with sticky lava and explosive eruptions, formed at convergent boundaries
- 6. of Fire - Zone around Pacific Ocean where 90% of earthquakes and 75% of volcanoes occur
- 7. - Steep-sided valley with flat floor, changed from V-shaped river valley by glacial erosion
- 9. - Process where denser oceanic plate sinks beneath lighter continental plate
- 10. - Material deposited by glaciers (Terminal, Lateral, Medial, Ground types)
- 11. Slip - Circular motion of ice advance that hollows and deepens the landscape
- 12. - Point below Earth's surface where an earthquake begins
- 14. - Economic activities extracting natural resources from Earth
- 15. - Mountain pool or lake formed in a corrie after the glacier has melted
- 19. - Plate boundary where plates move toward each other, denser plate subducts
- 21. - Circular movement of magma caused by heating and cooling, driving plate movement
- 23. - Rounded, steep-sided 'armchair' shaped hollow formed by glacial erosion with a lip at the bottom
- 24. - Erosion process where rocks, stones and boulders stuck in ice grind against rock below, wearing it away
- 25. - The process where snow and ice melts, typically during summer
- 26. - Large, slow-moving rivers of ice formed from layer upon layer of falling snow compressed over 20-30 years
- 27. - Process of increasing connections between countries through trade, culture and technology
- 28. - Semi-molten layer about 2900km thick, less dense than outer core
- 30. - Average number of years a person can expect to live
- 31. - Glacial erosion process where meltwater freezes around rocks and the glacier pulls the rock away as it moves
- 32. - UN measure combining life expectancy, education and income, scored 0-1
- 35. - Recently compressed ice that looks like small pieces of crushed ice
- 36. - Outermost layer of varying thickness made of two types of crust
