What causes the formation of rocks identified by the characteristic of graded beds of sediment?
Graded beds of sediment are typically formed by turbidity currents in water environments or by debris flows on land. These currents transport a mixture of different-sized sediments, with larger particles settling first as the flow slows down, creating the graded bedding pattern.

What are the causes of soil formation?
The primary causes of soil formation are weathering of rocks, organic matter decomposition, and biological activity. Weathering breaks down rocks into smaller particles, while organic matter decomposition adds nutrients to the soil. Biological activity such as plant roots and soil organisms further contribute to soil formation.
What agent of erosion causes material to tend to move downhill?
Gravity is the agent of erosion that causes material to tend to move downhill. As gravity pulls on the material, it causes it to slide, roll, or flow downhill. This process can lead to the transportation of sediment and the formation of landforms such as slopes and valleys.
Describe the sequence of events in the formation of a sandstone?
The formation of sandstone involves two principal stages. First, a layer or layers of sand accumulates as the result of sedimentation, and then the sand becomes sandstone when it is compacted by pressure of overlying deposits.
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.
How does wind cause deposition?
Wind causes deposition by carrying sediment particles, such as sand and dust, and depositing them when its speed decreases. When wind encounters obstacles or changes in landscape, it loses energy and drops the sediment it was carrying, leading to the formation of sand dunes, loess deposits, or other wind-formed landforms.
What causes the formation of soil?
Erosion and sediment ion
Why does the formation of a beach depend upon constructive waves?
Constructive waves deposit sediment carried by the waves onto the shore, gradually building up the beach. As the waves break, they lose energy, which causes them to drop sand and other materials they were carrying. Over time, this accumulation of sediment creates the characteristic sandy beach found in coastal areas.
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.

What are the causes of soil formation?

How do sediments affects organisms in water?
sediment causes H2O to discolor. also sediment causes some submerged vegetation to die.
How does wave affect sediment?
Waves can affect sediment by picking up particles from the seafloor and transporting them along the coastline, a process known as longshore drift. Strong waves can also erode coastal areas, moving sediment away and potentially shaping the land through processes such as beach erosion or cliff retreat. Additionally, waves can deposit sediment brought in from offshore, contributing to the formation of beaches and coastal landforms.
What is spit formation?
A spit is formed due to the process of the long shore drift, the waves approach the beach in the direction of the prevailing winds, this causes the sediment to be pushed up the beach at an angle.
What agent of erosion causes material to tend to move downhill?
Gravity is the agent of erosion that causes material to tend to move downhill. As gravity pulls on the material, it causes it to slide, roll, or flow downhill. This process can lead to the transportation of sediment and the formation of landforms such as slopes and valleys.
What causes formation of alluvial fan?
Alluvial fans are formed when a fast-flowing stream or river suddenly encounters a flat or gently sloping plain, causing the water to slow down and deposit sediment. This sediment builds up over time, creating a fan-shaped deposit. Factors such as the gradient of the slope, the volume of water, and the size of the sediment particles all play a role in the formation of alluvial fans.

Why is the Betsiboka river orange?
Due to the sediment within the river. this sediment causes the river to appear orange/reddish
