When rocks and rock fragments fall freely through the air, they experience a process known as free fall, where they accelerate downwards due to gravity. As they descend, they may encounter air resistance, which can slow their fall depending on their size and shape. Upon reaching the ground, the impact can cause fragmentation, create craters, or contribute to erosion and sediment deposition. This process is a key element in rock weathering and landscape shaping.
What else can I help you with?
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 are sedimentary rocks of weathered rock fragments called?
Sedimentary rocks made of weathered rock fragments are called clastic sedimentary rocks. These rocks are formed from the accumulation and cementation of fragments that have been weathered, eroded, and transported from their original source. Examples include sandstone, shale, and conglomerate.
What are breccias and conglomerates examples of?
Breccias and conglomerates are examples of sedimentary rocks composed of angular fragments. Breccias contain coarse fragments while conglomerates contain rounded fragments. They are formed through processes like compaction and cementation of sediments.
Rocks made of other rock fragments cemented together are called?
Rocks made of other rock fragments cemented together are called sedimentary rocks. These rocks form through the deposition and solidification of sediments, such as sand, clay, and pebbles, that have been compacted and cemented together over time.
What is fragments of other rocks?

What type of mass movement occurs when rock fragments of rocks fall freely through the air?
Rockfall.
What type of mass movement occurs when rock fragments or rocks fall freely through the air?
The type of mass movement that occurs when rock fragments or rocks fall freely through the air is called rockfall. This can happen due to weathering, gravity, or seismic activity, causing rocks to become dislodged and plummet downwards. Rockfalls can pose hazards to people, infrastructure, and the surrounding environment.
Downward rapid movement of rocks resulting in mass wasting is called?
The downward rapid movement of rocks resulting in mass wasting is called rockfall. It occurs when rocks or rock fragments fall freely through the air due to the force of gravity.
What occurs when rocks or rock fragments fall freely from the air?
When rocks or rock fragments fall freely from the air, they can create an impact force upon hitting the ground that can cause damage to property or injure individuals. Depending on the size and speed of the falling rocks, they can also trigger landslides or other geological hazards in the area where they land.
What type of mass movement occurs when rock fragment or rock fall freely through the air?
The type of mass movement that occurs when rock fragments or rocks fall freely through the air is called rockfall. It typically happens in steep, rocky areas due to gravitational forces, weathering, or seismic activity. Rockfalls can be dangerous and cause injury or property damage.
What is the same between rockfall and rockslide?
they both involve rocks that are moving down hill

What weathering occurs when rocks are broken apart by physical processes?
Mechanical weathering occurs when rocks are broken apart by physical processes such as frost wedging, root wedging, or abrasion. These processes break down rocks into smaller fragments without altering their chemical composition.
What makes a clastic rock different from a bioclastic rock?
A Clastic sedimentary rock forms when fragments of preexisting rocks are compacted or cemented together. A Bioclastic rock is a clastic rock but the fragments are not of preexisting rock but of organic shell and or bone fragments.
What are sedimentary rocks of weathered rock fragments called?
Sedimentary rocks made of weathered rock fragments are called clastic sedimentary rocks. These rocks are formed from the accumulation and cementation of fragments that have been weathered, eroded, and transported from their original source. Examples include sandstone, shale, and conglomerate.
