Where can a feature of scree be found?
A feature of scree, which is a widespread debris field of broken rocks at the base of cliffs or hillsides usually created by frost shattering, can be found in mountainous regions, particularly in areas with steep slopes and loose rock material. It is commonly seen in alpine environments and can also be found in coastal cliffs or areas with rocky terrain.
What type of landform causes a landslide?
Steep slopes or cliffs are common landforms that can cause landslides due to the force of gravity pulling loose soil or rocks downhill. Other factors such as heavy rainfall, erosion, or human activities can also contribute to triggering a landslide on these types of landforms.
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.
Why are landslides common in California?
Landslides usually occur after an earthquake so they are quite likely to occur in Hawaii because of it's seismic and volcanic activity they are also common in the cascade mountains.
Which Weakenes rock on steep slopes that suddenly gives away and falls down is an example of what?
That is an example of a rockfall, which is a type of mass wasting where rocks or rock fragments fall freely through the air. This process is common on steep slopes where loose rocks are unstable and can easily become dislodged and fall.
What is Colluvial?
Colluvial soil is the loose soil particles that derived from rocks and accumulated through the action of gravity at the base of steep slopes or cliffs.
What is a sediment that is carried down mountain canyons and deposited on the gentle slopes at the base of the mountains?
The sediment that is carried down mountain canyons and deposited on the gentle slopes at the base of the mountains is called alluvium. This alluvial deposit typically consists of a mix of sand, silt, clay, and gravel that has been transported by water flow and deposited as the flow velocity decreases on the gentler slopes.

What is colluvial soil?
Colluvial soil is a type of soil formed by the downhill movement of soil material due to gravity. It is often found at the base of slopes or hills and is characterized by its mixed composition of various soil types and rock fragments. Colluvial soil tends to be loose and poorly structured, making it susceptible to erosion and instability.
What type of landform causes a landslide?
Steep slopes or cliffs are common landforms that can cause landslides due to the force of gravity pulling loose soil or rocks downhill. Other factors such as heavy rainfall, erosion, or human activities can also contribute to triggering a landslide on these types of landforms.
Why are there large scree slopes at the bottom?
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 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.
Where could you find rock debris fragments in loose layers?
You could find rock debris fragments in loose layers in areas where there has been erosion, such as on the sides of cliffs, riverbanks, or at the base of steep slopes. These fragments could come from rockfalls or weathering processes that break down larger rocks into smaller pieces.
A smaller volcano with steep slopes. A volcanic cone built entirely of loose fragmented material?
Cinder cone
Why are landslides common in California?
Landslides usually occur after an earthquake so they are quite likely to occur in Hawaii because of it's seismic and volcanic activity they are also common in the cascade mountains.
What are the factors that make slopes more susceptible to the pull of gravity?
Factors that make slopes more susceptible to gravity include steepness of the slope, presence of loose or erodible material, amount of rainfall or water flow, and vegetation cover. Steeper slopes with less vegetation and more loose material are more likely to experience gravity-driven processes like landslides or erosion.
Falling rock signs mean what?
Look out for falling rocks. The area along the road is unstable and rocks could fall loose onto the roadway. The sign is warning that you should be vigilant for objects in the road.
