Systems are made up of five parts; inputs, outputs, stores, flows and boundaries.

What are the boundaries in a natural system?

• Where matter or energy is added to the system

• Where matter or energy leaves the system

• The physical outer limits of the system

(a) ................ is anything that occupies space and has mass. (b) ............. is the capacity to do work, or to put matter into motion.

• (a) Energy

  (b) Matter

• (a) Matter

  (b) Energy

.............. or transfer occurs when matter or energy moves from one store to another

• flow

• input

• output

At what point in a drainage basin (a natural system), does the flow or transfer become an output?

• Where the water enters the floodplain

• Where the river meets the ocean

• Where the water enters the river

A .................is a ridge of high/higher land dividing two areas that are drained by different river systems.

• floodplain

• valley

• watershed

Water travels from the drainage basin to the river and then down the river towards the ocean.

Where might some of the water be stored within the basin?

_{There are two correct answers}

• vegetation

• waterfalls

• soil

• impermeable rock

Natural systems like drainage basins do not have multiple inputs, outputs, stores and flows.

• True

• False

Energy and matter can enter and leave ..................

• a closed system

• an open system

• an isolated system

.............................. is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail.

Matter cannot enter or leave a closed system it can only cycle between ..................

• boundaries

• stores
