Resources
- Asia’s climate can be divided into three zones: North/Central, Southwest, and Southeast
- North/central Zone–
- The North/Central zone is affected by cold and dry Arctic winds, with permanent frosts that inhibit plant growth
- Hardier grains like barley, buckwheat, millet, oats, and wheat are grown in the central and southern areas, and animal husbandry is also important
- Southwest–
- The Southwest zone is a dry, hot region stretching from the Gobi Desert through Pakistan, Iran, and the Arabian Peninsula
- Grains like barley and corn are principal irrigated crops, while fruit and vegetable crops include dates, figs, apricots, olives, onions, grapes, and cherries
- Southeast–
- The Southeast zone is greatly affected by the summer monsoon season
- Rice is a major food staple and tropical fruits such as mango, papaya, and pineapple are important crops
- Many regions grow wheat where rainfall is less, and India is the world’s largest mango-producing nation
- Mining:
- China, India, Russia, and Indonesia are the continent’s most productive mining economies.
- China is the world’s largest producer of aluminum, gold, tin, and coal.
- India is also a major producer of aluminum and iron ore, along with other minerals such as barite, chromium, and manganese.
- Russia is a major producer of coal, tungsten, diamonds, iron, and steel.
- Indonesia is a major producer of coal, gold, copper, and tin.
- Drilling:
- Countries on the Arabian Peninsula have the world’s largest deposits of oil and natural gas.
- The oil found throughout the Arabian Peninsula and the Middle East is of the highest quality: light sweet crude.
- Light sweet crude oil is used to make gasoline, kerosene, and diesel fuels.
- Saudi Arabia was the world’s largest manufacturer of petroleum liquids in 2010, producing 10.07 million barrels of liquid fuels every day.
- Russia has oil reserves in Siberia and massive natural gas reserves throughout the Arctic.
- Russia and Iran have the world’s largest reserves of natural gas, while the US produces the most.
