Higher altitudes may have a greater impact on the formation of scree as the freeze-thaw cycle is more pronounced in colder temperatures, leading to more frequent rock fragmentation. Additionally, increased wind and precipitation at higher altitudes can contribute to the breakdown of rocks into scree material.
This may be known as a scree slope or a talus pile. Talus and scree are normally used interchangeably, however scree normally refers to material of gravel size or smaller and talus to larger debris.
Both scree and talus are a collection of broken rock fragments, such as at the foot of a cliff. Scree has smaller fragments- about golf ball sized, where talus is a bigger chunk of broken rock. "The footing was very poor when crossing over the field of scree." Think of a pile of big gravel.

Heaps of frost-weathered rock fragments are known as scree or talus. They form when frost action causes rocks to fracture and break apart, creating a loose accumulation of debris at the base of cliffs or steep slopes. Scree can be found in mountainous and glaciated regions.
Weathered rock fragments at the bottom of a hill are called scree. Scree formation is commonly attributed to the formation of ice within mountain rock slopes.

Freeze-thaw weathering occurs when water seeps into cracks in rocks, freezes, expands, and breaks the rock apart. Over time, this process weakens the rock, causing it to fragment and break into smaller pieces. The repeated cycles of freezing and thawing can lead to the formation of scree slopes as the broken rock fragments accumulate at the base of steep slopes.
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
One effect of being at a low altitude is higher air pressure, which can increase the amount of oxygen available for breathing. This can lead to improved physical performance and reduced risk of altitude sickness.

Simply put, the higher the altitude, the lower the density of the air molecules.
Thrust would drop as altitude goes up.

That heavy tobbogan I'd been dragging along was quite handy when our progress seemed to be halted by the swath of scree in our path. That toboggan careened wildly as we screamed down the scree. Unless my life depends upon it, I'll never ride another toboggan down the scree.
