Pronunciation: [nˈə͡ʊlz] (IPA) 
The word "knolls" is spelled with a silent 'k'. The correct phonetic transcription is /noʊlz/. The 'k' is there for historical reasons, as the word used to be pronounced with a pronounced 'k' sound in the past. However, over time, the 'k' has become silent and is no longer pronounced. The 'kn' sound in the beginning of the word is a common feature in English words of Germanic origin, such as "knight" and "know".
Knolls are defined as small, rounded hills or mounds that are typically found in natural landscapes. These elevated landforms are characterized by their gentle slopes and rounded or rounded-convex tops, which distinguish them from steeper, sharper peaks. Knolls are commonly formed through various geological processes such as erosion, sediment deposition, or glacial activity.
These land formations often have a distinct appearance that sets them apart from the surrounding terrain, as they stand slightly higher and exhibit a defined bulge or elevation. Knolls may vary in size, ranging from just a few meters in diameter to larger structures that can span tens or even hundreds of meters.
Knolls can be found in various environments, including grasslands, woodlands, coastal areas, or even deserts. They are significant features in the landscape, not only for their topographical characteristics but also for their ecological importance. These elevated areas can provide habitats for distinct plant and animal species, creating diversity within a region. Additionally, knolls can impact water drainage patterns, influencing the distribution and availability of water resources in an ecosystem.
In sum, knolls are small, rounded hills or mounds that emerge through natural geological processes. They contribute to the overall landscape by adding diversity, housing unique flora and fauna, and influencing water drainage patterns.
The word knolls has an Old English origin. It is derived from the word cnoll, which meant a small, rounded hill or mound. This ultimately traces back to the Proto-Germanic word knulaz.
