Answer:
Depression in the middle refers to basin whereas circular shape at the middle denotes dome.
Step-by-step explanation:
If this large bullseye structure has depression in the middle and the sides are higher than the middle region so it is known as basin while on the other hand, if this large bullseye structure has rounded uplifted landform so we can say that it is a dome. The structure of basin looks like a bowl which has low length at the middle and higher length at the bottom whereas dome has circular surface having sides of low height and middle is more in height.
