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.

What are the parts of a mountain?
A mountain typically consists of a peak or summit, slopes, a base or foothills, and sometimes plateaus or ridges. The slope can be composed of different geological features such as cliffs, scree slopes, and talus fields. Additionally, mountains often have a variety of flora and fauna adapting to the different elevations and climates.
How does mountain become a hill?
Over time, mountains can erode due to factors like weathering and tectonic activity, which can gradually reduce their height and steepness. As a mountain erodes, it may eventually be classified as a hill based on its elevation and slope characteristics.
What most likely formed the valley?
The valley was most likely formed by a combination of erosion from water, ice, or wind over a long period of time, carving out the landscape and creating the distinct valley shape. Factors such as the type of rock, slope of the land, and climate conditions can also influence the formation of valleys.
A sharp drop from a continent to an ocean basin is called what?
A sharp drop from a continent to an ocean basin is called a continental slope. This feature marks the boundary between the continental shelf and the deep ocean floor.
Which continent has the steepest slope?
Antarctica has the steepest average slope of any continent, with much of its surface being covered by thick ice sheets that can create steep gradients.
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.
Is freeze thaw chemical weathering?
No. Chemical weathering is to do with acidic rain. This is a type of physical weathering, where it isn't the rainwater's ph, but the fact it freezes in cracks, expands, and prises the rock apart(creating a broken skyline or a scree slope). It occurs in damp areas where water is sometimes, not always below freezing.
What is a talus field and how is it formed?
Talus, also called scree, is a term given to an accumulation of broken rock fragments at the base of crags, mountain cliffs, or valley shoulders. Formation of scree or talus deposits results from physical and chemical weathering and erosional processes acting on a rock face. The predominant processes that degrade a rock slope include: Mechanical weathering by ice Chemical weathering by mineral hydration and salt deposition Thermal stresses (heating by the Sun and cooling at night) Topographic stresses (stress from the rock formation process) Biotic processes (plants wedging themselves in cracks and crevasses)
How does a mountain slope form?
Scree slopes are common in upland areas, such as the Lake District. The scree - broken fragments of rock - is usually formed by freeze-thaw activity. This breaks solid rock into smaller, often angular particles. Scree is common in mountainous areas, since night-time temperatures often fall below freezing point, and there is a ready supply of moisture to freeze. A typical lowland glaciated valley can be seen in the background. Scree slopes are common in upland areas, such as the Lake District in northwest England. The scree, broken fragments of rock, is usually formed by freeze-thaw activity. This breaks solid rock into smaller, often angular particles. They are common in mountainous areas, since night-time temperatures often fall below freezing point, and there is a ready supply of moisture. Scree slope and cliffs near Eldborg, an ancient volcanic crater, in southern Iceland. Rocks fractured and broken apart by freeze-thaw action here form slopes of loose material. The slopes are very similar to the landscape of hot desert areas. Areas such as southern Iceland - which are called periglacial (literally on the edge of glacier activity) - are sometimes called cold deserts. Pile of rubble and sediment that collects at the foot of a mountain range or cliff. The rock fragments that form scree are usually broken off by the action of frost (freeze-thaw weathering). With time, the rock-waste builds up into a heap or sheet of rubble that may eventually bury even the upper cliffs, and the growth of the scree then stops. Usually, however, erosional forces remove the rock waste so that the scree stays restricted to lower slopes.
What is a large pile of debris that forms at the base of a slope?
Scree or Talus .
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 Material accumulates at the bottom of a steep slope?
The rock fragments that accumulate at the base if a steep slope are usually known as scree or talus.
How is surface related to weathering?
How does slope affect the rate of weathering
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 is the scrambled word for seeCr?
Those letters will spell scree (loose stones that cover a slope).

How do rockfalls occur a year?
Rockfalls occur each year due to steep slopes at a near vertical (80-90 degrees). There is no soil or vegetation on the rock face which causes instability and is a huge contributor to the formation of a rock fall. The rock face is usually always exposed and suffers from weathering on a regular basis this causes the well jointed rock to become weaker. Freeze thaw is also another condition, water seeps into cracks of the well jointed rock face and freezes during the night. Soon it expands , eventually the rock will crack and loosen causing the rock to fall.Higher class 5A noticed that you had 'Freeze thaw is also another condition'. We would change this as Freeze thaw is a process. We would add that scree settles at an angle of around 30 degrees and protects the slope from further weathering.
