very slow downhill movement of rock and soil
Sediment that moves slowly downhill, particularly after cycles of freezing and thawing, is often referred to as solifluction. This process occurs when the upper layer of soil becomes saturated with water, causing it to lose cohesion and flow down slopes, especially in areas with permafrost. The repeated freeze-thaw cycles contribute to the gradual movement of the sediment over time, leading to distinct landforms and changes in the landscape.

no it is not melting is the reverse of freezing
Weathering is the process by which rocks break down in place to produce soils and sediments. It can occur through physical processes like freezing and thawing, as well as chemical processes like oxidation and hydrolysis. Over time, weathering contributes to the formation of Earth's surface features.
The process in which sediments move slowly downhill, is called creep. It is common where freezing and thawing occur. As ice expands in soil, it pushed sediments up. Then as soil thaws, the sediments move farther downslope. Over time, creep can move large amounts of sediment, possibly causing damage to some structures
When sediments move slowly downhill due to freezing and thawing, it is a process called solifluction. This occurs in areas with permafrost where the upper layer thaws during warmer periods and refreezes during colder periods, causing the sediment to flow downslope. Over time, this movement can lead to the formation of features such as solifluction lobes or terracettes.

creep
the result of freezing and thawing and freezing is frost boil
by the coldness of freezing and the warmness of thawing
Freezing and thawing are examples of phase changes that occur when a substance transitions between solid and liquid states due to changes in temperature. This process is known as freezing when a substance transitions from liquid to solid, and thawing when it transitions from solid to liquid.
creep mass movement occurs where ice wedging takes place.(ice wedging means the ground is freezing and thawing over and over again) As the ground freezes, it expands the water in the soil to push up the sediments. when the ground thaws out all the sediments will fall downslope. Creep is a slow process.

thawing
There are several ways that rock is broken down. One of these is wind. Another is water, especially the cycle of freezing and thawing.
Melting and freezing are the correct terms for this phase change.
