What type of urban sprawl has large groups of similar homes positioned far from urban centers?

The type of urban sprawl that has large groups of similar homes positioned far from urban centers is known as "Suburban Sprawl". Here are the steps to understand this:

1. Urban Sprawl: This is a term used to describe the expansion of human populations away from central urban areas into low-density, monofunctional and usually car-dependent communities. It's a common phenomenon in many parts of the world, particularly in developed countries.

2. Types of Urban Sprawl: There are several types of urban sprawl, including ribbon sprawl, leapfrog sprawl, and suburban sprawl.

3. Suburban Sprawl: This is the type of sprawl you're asking about. Suburban sprawl occurs when there is development in suburban areas, which are located on the outskirts of a city or town. These areas are typically residential in nature, and the homes are often similar in appearance. The development is usually far from urban centers, which can lead to increased reliance on cars and longer commute times.

So, the answer to your question is "Suburban Sprawl".
