Across:

2. When this is slow you get bigger igneous rock crystals from magma. (7)
5. This means 'sticking together' to make a hard material like grains of sand making sandstone. (11)
6. Add this to limestone and it fizzes. (4)
7. If this doesn't happen, you cannot get rocks from magma or lava! (5)
9. Limestone and sandstone are examples of this kind of rocks. (11)
10. Igneous rock of larger crystals formed from slow cooling magma deep underground. (6, not basalt)
11. The base of Hawaii is mainly formed from small ones formed when lava rapidly cools in the air or sea. (8)
14. Type of igneous rock with larger crystals from slow cooling of magma deep in the Earth. (7)
16. The rate at which rocks get recycled is very (4)?
19. Type of rock made from pre-existing rocks under the action of high temperature and pressure. (11)
20. Compounds of this metal give sedimentary rocks an orange or brown colour. (4)
22. (9)? is a sedimentary rock made from the mineral remains of sea organisms.
23. (5)? is a metamorphic rock used for roofing.
25. Very hot molten rock coming up from the mantle. (5)
28. (6)? is a metamorphic rock formed from limestone.
30. This mode of cooling makes small igneous rock crystals like basalt. (4)
31. It can be very dramatic, dangerous and unpredictable! (7)
33. A kind of sedimentary rock, often red or orange due to iron compounds. (9)
34. Type of rock made from cooled magma or lava. (7)
35. A descriptor that usually means the rock will easily absorb water. (6)

Down:

1. When this is high, rocks can be changed into another kind of rock without melting. (11)
3. These make volcanic rocks light and porous (3,7)
4. A rough value for the pressure or temperature to make metamorphic rocks! (4)
8. Molten rock that flows from a volcano. (4)
11. When this happens, water gets squeezed out from between the sand grains. (10)
12. A major component of many igneous rocks, formula SiO2 (6)
13. A type of very crumbly sedimentary rock, often has fossils in it and can have oil in it too. (5)
15. It has a high value deep in the crust. (8)
17. From slower cooling of magma, granite crystals compared to basalt crystals! (6)
18. One way by which sand grains are transported around. (4)
19. It happens to rock deep in the Earth's crust. (5)
21. The whole process! (4,5)
23. Sand grains are this! (5)
24. A light porous volcanic rock. (6)
26. If more than 1.0 the rock material sinks in water. (7)
27. Igneous rock of small crystals from fast cooling lava. (6)
29. This is what volcanoes do best for the tourist?! (5)
32. A tree flung out from volcanoes? (3)
