The process described is known as sedimentation. Sedimentation occurs when rocks or particles settle out of a fluid (like water or air) and accumulate in a new location, typically due to gravity or the slowing of the fluid's movement. Over time, these accumulated sediments can become compacted and cemented together to form sedimentary rocks.
Wind: Rock particles can be transported by wind through processes like saltation and suspension. Water: Erosion by water, such as rivers, streams, and ocean currents, can transport rock particles downstream or along coastlines. Ice: Glaciers can carry rock particles as they flow, depositing them when the ice melts. Gravity: Rock particles can be moved downslope due to gravity, such as in landslides, rockfalls, or creep. Human activity: Activities like construction, mining, or landscaping can also transport rock particles from one place to another.
Sand settles faster than rock because sand particles are smaller and lighter compared to rock particles. This allows gravity to exert a greater influence on sand particles, pulling them down to the bottom of a container or body of water more quickly. Rocks, being larger and heavier, have more inertia and are less affected by gravitational forces, which results in a slower settling rate.
Rock particles are moved from place to place primarily through the processes of erosion, transportation, and deposition. Erosion occurs when natural forces like wind, water, and ice break down rocks into smaller particles. These particles are then transported by these agents, often carried in water or air, until they settle in a new location through deposition. This cycle plays a crucial role in shaping landscapes and forming sedimentary rocks.
No. Limestone and shale are sedimentary rocks the form by different processes. Limestone is a biological sedimentary rock that forms from the carbonate shells of organisms. Shale is a clastic sedimentary rock the forms from the settling of fine-grained particles of mostly silicate minerals.
The rock formed when particles stick together is called Sedimentary Rock. The type of this rock depends on the composition and texture of the particles sticking together.
The dropping off of weathered rock is known as erosion. Erosion is the process where rocks and soil are loosened and moved by natural forces like wind, water, and ice, eventually settling in a new location.
The process is called deposition.

External processes of the rock cycle include weathering, erosion, transportation, and deposition. Weathering breaks down rocks into smaller particles, erosion moves these particles to new locations, transportation carries them further, and deposition involves the settling of these particles to form new rock layers.
In sedimentation, layers settle based on their particle size and density, with larger and denser particles settling at the bottom first. This process is known as sorting, with smaller and less dense particles settling on top of the larger ones. Over time, this leads to the formation of distinct layers in sedimentary rock.
The large rock weathers. Its particles are eroded to a place of deposition. The particles are compacted and cemented together, forming a new sedimentary rock. This is a simplified explanation of the process.
Rock particles.
The dropping off of bits of eroded rock, known as sedimentation, occurs when the energy of the transporting medium (such as water or wind) decreases, causing the particles to settle out. This process is crucial for shaping landforms, depositing nutrients in soil, and forming sedimentary rocks over time.
Wind: Rock particles can be transported by wind through processes like saltation and suspension. Water: Erosion by water, such as rivers, streams, and ocean currents, can transport rock particles downstream or along coastlines. Ice: Glaciers can carry rock particles as they flow, depositing them when the ice melts. Gravity: Rock particles can be moved downslope due to gravity, such as in landslides, rockfalls, or creep. Human activity: Activities like construction, mining, or landscaping can also transport rock particles from one place to another.
Yes, the particles in a rock do vibrate back and forth, but the movement is very small and not easily detectable without special equipment. This vibration is a result of the thermal energy present in the rock causing the particles to jiggle in place.
Dumping.
The dropping or settling of eroded materials is called deposition. This process occurs when the energy of the transporting agent (such as water or wind) decreases, causing it to drop the sediment it was carrying and build up sedimentary layers in new locations.
