What causes sediment and rock to move to lower elevations through time?
Sediment and rock move to lower elevations primarily due to the force of gravity acting on them. This process, known as erosion, is facilitated by various agents such as water, wind, ice, and gravity itself. Over time, the movement of sediment and rock contributes to the formation of landforms and reshapes the Earth's surface.
How do glaciers accumulate their load of sediment?
Glaciers accumulate sediment through various processes. As glaciers move, they pluck and erode rocks from the underlying bedrock, entraining them into the ice. Glaciers also grind and crush the rocks they come into contact with, generating glacial flour or fine-grained sediment. Additionally, glaciers can transport sediment that has been deposited on their surface by wind or landslides, adding to their load of sediment.
What normally carries the eroded rock pieces during transportation?
Water, ice, wind, and gravity are common agents that transport eroded rock pieces. Water from rivers, glaciers, or ocean currents can carry sediment downstream. Ice can transport sediment through glaciers. Wind can move sediment over long distances. Gravity can cause sediment to move downhill.
What causes rock or sediment to move downhill?
Gravity is the main force that causes rocks or sediment to move downhill. When the force of gravity overcomes the friction between rocks or sediment and the ground, they begin to slide, roll, or flow downhill. Other factors such as water, ice, or slope steepness can also contribute to this downhill movement.
What fine sediment results from the crushing of rock under a glacier?
Rock flour is the fine sediment that results from the crushing of rock under a glacier. This powdery substance is created through the grinding and crushing action of rocks carried by the glacier as it moves and scrapes against the underlying bedrock.
This type of formation moves sediment and erodes rock?
The formation that moves sediment and erodes rock is called a river. Rivers play a key role in shaping landscapes by carrying and depositing sediment, as well as by physically wearing down rock through the process of erosion.
What does slump in science mean?
gravity causing by rock or sediment to move downhill
how rock layers are deposited?
Scientists know that gravity cause sediment to be deposite.
How does rain form a landslide?
Rain causes rock and sediment to be loosened, and gravity does the rest
What does slump mean in science form?
gravity causing by rock or sediment to move downhill
What are the four agents erosion?
Water, ice, gravity, and wind.
Why does gravity cause layers of sediment to be horizontal?
Gravity causes layers of sediment to be horizontal because as sediment deposits, it settles evenly due to gravity pulling the particles downwards. Over time, as more sediment accumulates, the weight of the new layers causes the underlying layers to compact and settle into a horizontal orientation.
What type of formation moves sediment and erodes rock?
Water erosion is a type of formation that moves sediment and erodes rock. This can occur through processes such as rivers carving out canyons, waves breaking down coastlines, or glaciers scraping across land.
How can water and gravity work together to erode rock?
Water can flow over rock surfaces, carrying sediment and causing abrasion. Gravity helps in pulling this sediment downstream, wearing away the rock surface over time. The force of gravity also plays a role in causing water to flow downwards, increasing its erosive power on rocks.

Over time, the movement of sediment and rock contributes to the formation of landforms and reshapes the Earth's surface.
How weathering and erosion work together?
how can water and gravity work together to erode soil, sediment, and rock
What are rock slides?
A rock slide is a mass of freshly broken rock material that moves by gravity in one swift movement.
