Final answer:
The attempts to colonise Virginia in the 1580s included a failed attempt in 1585 on Roanoke Island and the successful establishment of Jamestown in 1607.
Step-by-step explanation:
Two features of the attempts to colonise Virginia in the 1580s were the initial failed attempt in 1585 on Roanoke Island and the successful establishment of a settlement called Jamestown in 1607.
The failed attempt left little more than terrain named Virginia, while the successful establishment of Jamestown marked the beginning of a tobacco economy and the arrival of the colony's first Africans.
