WORLD HISTORY

Detailed explanation-1: -After the last Ice Age ended, Earth’s temperatures rose. As the climate warmed, many nomads moved into areas with a mild climate and fertile land. Another historical revolution then occurred. For the first time, people began staying in one place to grow grains and vegetables.

Detailed explanation-2: -Barley and wheat were the most important crops in most European regions; oats and rye were also grown, along with a variety of vegetables and fruits. Oxen and horses were used as draft animals. Sheep were raised for wool and pigs were raised for meat.

Detailed explanation-3: -Climate scientists now understand that the Medieval Warm Period was caused by an increase in solar radiation and a decrease in volcanic activity, which both promote warming.

Detailed explanation-4: -Agriculture was the chief occupation of the people of medieval India. Cotton, cereals, pulses, indigo, sugarcane, etc. were the major crops. Many landless farmers brought uncultivated land under cultivation to obtain ownership of land.

Detailed explanation-5: -The Medieval Warm Period (MWP) was a time of warm climate from about 900–1300 AD, when global temperatures were somewhat warmer than at present. Tempera-tures in the GISP2 ice core were about 2°F (1°C) warmer than modern temperatures (Fig. 8.14).
