Across
- 2. Collapse of unstable mountain sides in a gorge due to erosion
- 3. Layer of hot, semi-molten rock beneath tectonic plates also known as the asthenosphere
- 6. A general term for the movement of rock or soil down slopes under the force of gravity
- 8. Group of processes which involves the actions of rivers and streams shaping the Earth's surface
- 12. Process at converging plate boundary where one plate moves beneath another
- 13. Shallow body of water connecting larger water bodies. The Manawatu Inlet was one of these before it became a gorge.
- 14. The centre of the Earth, which due to radioactivity reaches temperatures of up to 6000°C
- 17. Landmass formed by uplift in the East Coast 1 million years ago that was not connected to the rest of the North Island.
- 20. A significant object made by nature
- 21. Giant rafts of rock in the Earth's crust which move on the mantle
- 22. A process that uses the power of running water to wear away rock and soil
- 23. Lighter, thicker, granite plate in subduction zones
- 24. A water body that separated the North Island from the South-east Island about 1 million years ago.
Down
- 1. A water gap gorge where the Manawatu River cuts through the rising Ruahine and Taraua Ranges
- 4. A process whereby molten rock moves in a circular motion caused by heating and cooling of rock in the mantle
- 5. Unique gorge where a river predates the surrounding mountains
- 7. Erosion caused by water pressure against rock and soil
- 9. Denser, thinner, basalt plate in subduction zones
- 10. Feature or event that can be observed, usually considered extraordinary or remarkable
- 11. Rainwater draining from a region
- 15. Most mass wasting occurs due to persistent or heavy rainfall which can ___________ the slope
- 16. A series of events in nature that shapes the environment
- 18. A process which builds mountain ranges due to pressure when plates converge or transform
- 19. Type of erosion whereby water smashes sediment into the bed and sides of rivers, breaking them down.
