Large scree slopes form at the bottom of mountains due to the accumulation of loose rocks and debris that have weathered and eroded from higher elevations. As rocks break down from freeze-thaw cycles and other weathering processes, they fall under the influence of gravity, creating a cone-shaped deposit at the base. These slopes can be unstable and are often composed of various sizes of rock fragments. Over time, the continual process of erosion and the movement of material contributes to the growth of these scree slopes.

What causes rocks to break away from steep mountain slopes and accumulate as scree slopes?
Rocks break away from steep mountain slopes due to weathering and erosion processes, including freeze-thaw cycles, where water seeps into cracks, freezes, and expands, causing the rocks to fracture. Gravity plays a significant role, as loose material becomes unstable and falls down the slope. Additionally, seismic activity and human impacts can trigger rockfalls, contributing to the accumulation of debris at the base of the slopes, forming scree slopes. These slopes are characterized by an accumulation of angular rock fragments that have fallen from higher elevations.
What is a large pile of debris that forms at the base of a slope?
Scree or Talus .
What material making up a scree slope is called?
The material making up a scree slope is called "scree" or "talus." It consists of loose rock fragments that have fallen from a cliff or steep slope, typically due to weathering and erosion processes. These angular pieces of rock accumulate at the base of the slope, forming a steeply angled deposit. Scree slopes are often unstable and can shift or move due to gravity and other environmental factors.
What Material that accumulates at the bottom of a steep slope?
The general term for material that falls down and gathers at the foot of a steep cliff or mountain face is scree.
A high uplifted area with steep slopes?
A mountain is a high, uplifted area with steep slopes. Mountains are large elevated area that rises from level ground. They are large and steep hills.
A sloping mass of rock fragments below a cliff called?
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.
Why are large scree slopes found under cliffs and mountainous areas?
A scree slope is caused by weather erosion breaking off pieces of rock from the cliff and mountain-side.
What has the author Penelope Ann Crompton written?
Penelope Ann Crompton has written: 'Scree development on Eaffin Island' -- subject(s): Rock slopes, Scree
What is the land formed by deposition at the bottom of a mountain?
It is called scree.
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 is scree?
Scree is a collection of broken rock fragments found at the base of cliffs or steep rocky slopes. It is formed through the process of frost weathering, where water seeps into fractures in the rocks, freezes, and expands, causing the rocks to break apart and fall to the base of the slope.
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.
What is a large pile of debris that forms at the base of a slope?
Scree or Talus .
What type of home does a macaroni penguin have?
HABITAT Often nests on steep, rough terrain with little or no vegetation, including lava flows and scree slopes
What material making up a scree slope is called?

These angular pieces of rock accumulate at the base of the slope, forming a steeply angled deposit. Scree slopes are often unstable and can shift or move due to gravity and other environmental factors.
What do you call large masses of fallen rock?
One word you can use is scree.
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.
