The Earth is often described as an oblate spheroid, meaning it is round but slightly flattened at the poles and slightly bulging at the equator due to its rotation. This shape is more akin to a sphere than any other geometric figure, but the equatorial diameter is about 43 kilometers (27 miles) larger than the polar diameter.
In terms of smoothness, the Earth's surface is quite varied, featuring mountains, valleys, plains, and other geological formations. Thus, while the Earth as a whole is approximately round, its surface is not perfectly smooth. However, when viewed from space, the irregularities become less pronounced, and Earth appears as a relatively smooth, blue and green marble.
In summary, the Earth is rounded but not perfectly spherical, and while it has many surface irregularities, it can be considered smooth from a broader perspective.
