Rills are formed by erosion. As soil erodes a thin channel is left, this channel fills with water. Gullies are formed by running water. An area where many rills have formed can turn into a gully.
The network of rills, gullies, streams, and rivers in an area is often referred to as a watershed or river basin. This system of interconnected waterways ultimately drains into a common body of water, such as a lake or ocean.
A rill is a tiny grove formed in soil due to the flow of water. Rills typically develop on sloping terrain and are a result of erosion caused by rainfall or snowmelt. They are small channels that can eventually grow into larger features like gullies.

, too, assume you're talking about Mars simply because of the abundance of other Mars questions on here this morning. If you're not, my apologies. Anyway, the conclusion (gullies were created by water bubbling up to the planet's surface) is based on computer modeling of the atmosphere and how water would behave. However, there are other scientists that disagree and think the gullies could have been made by dust or wind. As evidence they point out similiar gullies on the Moon, where no water has been found.
These are all features associated with coastlines. Ripples are small waves found on sandy shorelines, rills are small channels formed by water flowing over the sand, backwash marks are the patterns left by the water moving back towards the ocean, and cusps are crescent-shaped indentations in the shoreline.
Rills and gullies are both landforms formed by erosion caused by flowing water. The main difference is in their size and scale: rills are smaller and shallower, while gullies are larger and deeper. Gullies tend to be more pronounced and have steeper sides compared to rills.
Over time, rills expand and join together causing gullies.

A rill is a much smaller channel. A gully was once a rill that got broader and deeper. There are another differences too: 1- Ratio of width to depth: In gully that ratio is approximately 1:1 but in rills width is greater than itsdepth. 2- In agricultural activities, rills can be removed but gullies can not. 3- In specific area, number of rills are higher than gullies. 4- sediment production of gullies is much higher than Rills.

Rills are small channels formed by flowing water on a slope, gullies are larger and deeper channels typically caused by erosion, and streams are larger bodies of moving water that can support aquatic life and flow towards a larger body of water like a river or ocean.
Tiny rills enlarge to form gullies, which join to form a stream.
Precipitation -- rain and snow cause flowing water in nature.
A large channel in the soil that carries runoff is typically referred to as a gully. Gullies are formed from erosion by flowing water and can vary in size and depth depending on factors such as slope, soil type, and vegetation cover. Addressing gullies is important to prevent further erosion and soil loss.
