Agricultural economies are still used in some countries of the Middle East, especially where other natural resources are few. These economies are often associated with a lower standard of living. Herding and livestock raising is a common means of income in areas too dry for farming. Animals raised include cattle, goats, and sheep. Farming often occurs along the coasts, but may also occur in drier areas if irrigation watering methods are used. Some people choose to practice subsistence farming methods, growing only enough food to feed their families. With little fertile soil in the region, it is tough to make a living growing and selling large quantities of crops. Major crops in the Middle East include wheat, cotton, and citrus fruit.

Explanation:
The changes that matter undergoes can be attributed to their properties.
Physical change is one of such.
- A physical change is one that alters the physical properties of matter especially its form and state.
- The physical properties of matter tells us everything about what a substance is when no change is occurring to its constituents.
- In most cases physical changes are usually reversible.
- Examples are boiling, melting, freezing, condensation, sublimation, magnetization of metals etc.
- Physical changes leads to the production of no new kinds of matter.
- They involve no mass change and requires little to no energy.
