21
Q

Describe how finance influences decisions on a farm?

A

Many farmers do not have the financial resources to buy machines and hire labour, thus they must rely on physical labour

22
Q

Describe how sunlight influences the decisions on a farm?

A

Places near to the equator receive more sunlight than places closer to the poles, influencing the length of the growing seasons

23
Q

Describe how soil influences the decisions on a farm?

A

Plants need certain minerals and trace elements to grow and they take these from the soil

24
Q

Describe how rainfall influences the decisions on a farm?

A

The amount of rainfall that plants need differs, but all plants need rainfall to survive

25
Q

Describe how temperature influences the decisions on a farm?

A

Different plants have different tolerances to temperature

26
Q

Describe how slope of land influences the decisions on a farm?

A

Flat areas, although at risk of flooding, are generally easier to farm on then hillsides, and slope of the land can be important in determining the amount of sunlight plants receive

27
Q

Describe how wind influences the decisions on a farm?

A
