1

igneous

magma that has formed in the air.

2

sedimentary rocks

rocks that have formed from waves crashing forming layers.

3

magma

melted rock mixture below earth's lithosphere.

4

lava

liquified rock that is very hot mostly found on the earth's surface

5

intrusive rock

magma or lava that has stayed in the lithosphere to turn into rock.

6

extrusive rock

rocks that have formed by lava or magma landing on the earth's lithosphere

7

mineral

formed substances that have formed to make rocks.

8

lithosphere

the surface above the asthenosphere, the lithosphere also known as the crust.

9

asthenosphere

the part of the earth directly above the mantle.

10

erosion

the disassembling of a rock from natural causes or human actions.

11

floodplains

the part that connects the activity of the waves affect the rocks, which in the middle is flat land.

12

glaciers

large boulders of ice with bits of rocks and gravel combined with the glacier.

13

moraines

deposits of glacier bits left behind because of movement.

14

sandstone

a combination of lime and salt combined with layers connected with silica.

15

mudstone

grained rock formed by water without layers.

16

shale

grained clay formed like mudstone but has layers.

17

siltstone

sedimentary stone with particle sizes of mudstone and sandstone.

18

conglomerate

a sedimentary rock with larger varied sizes of the sedimentary rock.

19

limestone

sedimentary rock mainly consists mostly of sea life organisms which are usually calcium

rock salt

sedimentary deposit of a lake that has dried up and has left all the salt.

22

Metamorphic rocks

a rock that has transformed from its original state into a more additional version.
