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.

A pile of rock fragments at the base of a cliff is called a?

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.


What effect does altitude have on the formation of scree?

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.


What heaps of frost-weathered rock fragments?

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.


What type of physical weathering forms scree?

Frost shattering is a type of physical weathering that can form scree. This occurs when water seeps into cracks in rocks, freezes, expands, and breaks the rocks into smaller pieces. Over time, these broken rocks accumulate to form scree slopes.


What are small loose stones at the bottom of a cliff called?

Small loose stones at the bottom of a cliff are commonly referred to as scree. Scree is made up of loose rock fragments that have accumulated due to erosion and weathering processes. It can be unstable and make hiking or climbing difficult.
