The land is relatively flat.
Ocean basins are not completely flat; they feature a variety of geological structures, including mountains, valleys, and trenches. While the abyssal plains, which make up a significant portion of ocean basins, appear relatively flat and smooth, other features like mid-ocean ridges, seamounts, and deep-sea trenches contribute to a more complex topography. Overall, the ocean floor is characterized by a diverse range of landscapes, contrary to the notion that it is just a flat plain.
A region of flat land is called a plain. Plains are characterized by low elevation and relatively flat topography, making them ideal for agriculture and transportation.
Ottawa is not completely flat, but it does have a relatively flat terrain compared to other regions in Canada. The city is located on the Ottawa River, with some rolling hills and valleys throughout the area.
A plateau is a relatively flat area that has high elevation compared to its surrounding land. Plateaus are characterized by their flat top surface and steep sides, often formed through volcanic activity or tectonic processes.
It is the continental shelf.

A flat circular object is called a disk or a round.
A cylinder has 2 flat circular faces.
The object described is a cylinder, specifically a right circular cylinder. It is a round solid with flat circular ends.
A cone has a flat circular base
A round object with flat, circular ends is a cylinder. It is shaped like a can of vegetables.
No one knows that because we have not explored outside the universe. If you are thinking about the galaxy, it looks like a straight line from Earth and a circular object from outside the galaxy.
The sheep's eye is concave, the surface of the shape of the lens are circular.
A solid figure that has a flat surface that is a circle is a cylinder. A cylinder consists of two circular bases connected by a curved surface. The flat circular surfaces are at the top and bottom of the cylinder. Another example is a sphere, which has a circular cross-section but is not flat overall.
