Answer :
a. The volcano features of East Asia, such as the ones found in the Ring of Fire, have had both positive and negative effects on the movement of people, animals, and ideas. On one hand, volcanic activity has provided fertile soil for agriculture, leading to the development of settled communities and the growth of civilizations. On the other hand, volcanic eruptions and earthquakes can lead to displacement and migration of people, as well as the destruction of infrastructure and loss of life. Additionally, the volcanic mountains in the region have also served as physical barriers, hindering the movement of people and ideas.
b. The geographic features of West Asia, such as the deserts, mountains, and rivers, have greatly influenced the movement of people, goods, and ideas throughout history. The deserts have historically been seen as formidable barriers to human movement, but also provided trade routes for caravans. The mountains have also served as barriers, but also provided resources such as timber, minerals, and water. Rivers have been important for transportation, irrigation, and the development of settlements.
c. The geographic features of East Asia, such as the mountains, deserts, and seas, have had a significant impact on the movement of people, animals, and ideas.
