Is the fan-shaped pile of broken rock fragments at the base of a steep bedrock slope or cliff?
The fan-shaped pile of broken rock fragments at the base of a steep bedrock slope or cliff is known as a talus slope or talus cone. This debris results from the weathering and erosion of the bedrock above, where gravity causes the rock fragments to accumulate at the base of the slope.

What sentence with the word scree?
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.
What is One effect of weathering on a cliff?
One effect of weathering on a cliff is the gradual breakdown and weakening of the rock surface, leading to the formation of cracks and crevices. This can eventually result in the detachment of rock fragments and the formation of rockfall debris at the base of the cliff.
What is an abrasion platform?
An abrasion platform is a sloping or flat bedrock surface extending out from the foot of a marine cliff under shallow water of a breaker zone, created by marine abrasion.
Diagram of cliff that is being weathered?
Weathering processes act on a cliff face through physical and chemical mechanisms. Physical weathering, such as freeze-thaw cycles and salt crystallization, causes rock to break apart into smaller fragments. Chemical weathering, like oxidation and hydration, alters the mineral composition of the rock. Over time, these processes can cause the cliff face to erode and change in appearance.
What is the term used for fallen disintegrated material found at the base of a cliff?
The term used for fallen disintegrated material found at the base of a cliff is "talus." Talus consists of rock fragments and debris that accumulate at the base due to weathering and erosion processes. This accumulation can create a sloping surface known as a talus slope.
What term describes an accumulation of angular rock fragments at the base of a steep bedrock slope or cliff?
Talus or scree is the term used to describe an accumulation of angular rock fragments at the base of a steep bedrock slope or cliff. This process is commonly associated with physical weathering and erosion.
What do bedrock material that are broken from a cliff and deposited by a landslide at the base of the cliff look like?
The deposit is known as scree. The scree is like a steep ramp of very loose stones and boulders that have tumbled down due to the eroding of the cliff or mountain.

What landscape feature is most likely to be formed from a bedrock layer that is resistant to erosion?
A ridge or a cliff would be most likely to form from a bedrock layer that is resistant to erosion. These features are created when surrounding softer rock is worn away, leaving the harder bedrock exposed.
What is One effect of weathering on a cliff?
One effect of weathering on a cliff is the gradual breakdown and weakening of the rock surface, leading to the formation of cracks and crevices. This can eventually result in the detachment of rock fragments and the formation of rockfall debris at the base of the cliff.
What is an platform?
An abrasion platform is a sloping or flat bedrock surface extending out from the foot of a marine cliff under shallow water of a breaker zone, created by marine abrasion.

What is cliff retreat?
A cliff retreat is a form of natural erosion. Rocks in the face of the cliff are broken down by wind and water (rain, waves, etc). The material in the cliff is loosened, and parts of the cliff face collapse. Eventually, an entire section of the cliff will fall into the sea, meaning that the cliff edge has retreated. The pace of cliff retreat is determined by the strength of the rocks in the cliff face, more than the cliff's height. It also most often occurs where the base of the cliff is continually being saturated by water, weakening the rock further.
What is the accumulation of rock debris at the base of a cliff called?
The accumulation of rock debris at the base of a cliff is called talus or scree. It forms as a result of weathering and erosion causing rock fragments to break off from the cliff face and accumulate at the bottom.
Where would you expect to find talus?
You would expect to find talus at the base of a cliff or steep slope. Talus consists of loose, fragmented rock debris that has accumulated from the erosion of the cliff or slope above. It often forms a slope of angular rocks and boulders created by gravity pulling the rock fragments downhill.
What type of erosion is a cliff?
When a wave impacts a cliff face, air is forced into cracks under high pressure, widening them. Over long periods of time, the growing cracks destabilise the cliff and fragments of rock break off of it
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.
