the structure of the earth:
- crust
- mantle
- core


the process of metamorphic rocks is when the volcanic errupt (lava) from igneous rocks and because of the heat and pressure and stress, they will form metamorphic rocks.

coal is solid fossil fuel formed from land plants that lived 300-400 million years ago.

because of the burial pressure, heat, and time they will change from lignite to sub-bitumunious and then bitumunous and anthracite


Folding = the bonding of rock layers due to stress in the earth's crust.
Faulting: a crack in the earth's surface where two pieces of land have moved in different directions.

there are 5 ways in which mountain are formed:
1. volcanic activity
2. folding
3. faulting
4. dome building
5. erosion


ways of improving water quantity, quality and access. the first is polution control. 2. improved sanitation 3. distribution for more efficient water use. 4. desalination


strategies for the sustainable harvesting of ocean fisherist.
1. net types and size
2. quotas
3. conservation laws
4. teritoriality


location of major climatic types and and their men characteristic interplation of climatic graps and maps.
1. tropical . eg. equatorial and savanah
2. dry e.g dessert
3. temperate  e.g coal interiror
4. colt " tundra
