Plate tectonic theory
The earth is made up of crust that has been Broken up into many large pieces . Made up of oceanic and continental crust
Convection currents
Very hot material at the bottom of the mantle rises up to the top and hits the crust. As it hits the crust it cools and sinks to the bottom. When it sinks back down it reheats and rises again. This cycle helps the plates move

Ecosystems
A complex, self regulating system where living things ( biotic ) interact with each other and non-living things ( abiotic ) These interactions help keep ecosystems sustainable and healthy
Climate
The average weather conditions of a particular place over a long period of time
Weather
The day to day weather conditions in the earth’s atmosphere ( short term )
Why is soil important
Soil is the basis of life. Without soil plants cannot survive. Without plants animals cannot survive.
Ecology
The study of the interactions of living organisms with each other and with non-living things in their environment
Magma
Liquid molten rock found inside the earth
Divergent
Two plates pulling apart
Convergent
Two plates coming together
Transform boundaries
Two plates sliding past each other in opposite directions
Biotic
Living things ( things that can die ) EX. Plants, animals, fungi, bacteria
Abiotic
Non-living things ( things that cannot live or die ) EX. Rocks, air, soil, water, temperature, light
Stewardship
A way of acting that involves taking personal responsibility for the care of something
