Final answer:
The Arab Empire's expansion brought changes like the spread of Islam and complex administration but also maintained continuities such as the use of Arabic language and a deep respect for knowledge and learning.
Step-by-step explanation:
The growth of the Arab Empire over several centuries brought about a significant number of changes and continuities. A prominent change was in the realm of religion, with the spread of Islam being a defining feature of the Arab Empire's expansion. While Christianity and Judaism continued to exist, the dominant religion became Islam, dramatically altering the religious landscape. Another change was the growth and complexities of administration as the empire expanded to include more diverse cultures.
Despite these changes, there were also continuities. The use of Arabic language as the literary and administrative language remained constant, even as the empire grew and included non-Arab peoples. The respect for knowledge and learning stayed strong throughout, with the empire making considerable contributions to science, technology, arts, architecture, and philosophy.
