Depending on when it was formed, the size and speed it is moving it could be either an Avalanche or Glacier. If it is an incredibly old, slow moving, large, ice mass it is likely a Glacier; however if it is a quickly moving, small (relatively), ice mass it is an Avalanche.
glacier
A glacier moving down a mountain is an example of something that moves very slowly. It can take many years for a glacier to travel a short distance due to its slow rate of movement.
The theory of plate tectonics states that the Earth's surface is divided into several large and slow-moving plates that float on the semi-fluid asthenosphere beneath them. These plates interact at their boundaries, leading to processes such as earthquakes, volcanic activity, and mountain formation. The movement of these plates has shaped the Earth's surface over millions of years.
A slow moving photon has a longer wavelength compared to a fast moving golf ball. Wavelength is inversely proportional to speed, so the slower the object, the longer the wavelength.

Gravity.
It's called a turnout.
A slow moving giant could refer to a large animal like an elephant or a sloth, which are known for their leisurely pace of movement due to their size or behavioral characteristics. It could also be metaphorical, describing something large and powerful but slow to act or progress.
They are generally slow.
I know that cranes are birds but I do not know that they are slow moving.

fast moving
Water typically flows faster moving down a mountain due to the steep gradient, while it may slow down when moving through a valley due to the more level terrain. The speed of water flow also depends on other factors such as the volume of water, obstacles in its path, and the width of the channel.
