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) |
