Explain how the cobbles and pebbles that were transported by these streams become smooth and rounded in shape?
As the cobbles and pebbles are carried downstream by the stream, they constantly collide with each other and with the streambed, causing abrasion. This abrasion gradually wears away the rough edges and corners of the rocks, resulting in their smooth and rounded appearance. The longer the rocks are transported by the stream, the more worn down they become.
What happens when weathering and erosion work together?
When weathering and erosion work together, rocks are broken down and then transported away. Weathering breaks rocks into smaller pieces, while erosion carries these pieces away through processes like wind, water, or ice. Together, they shape the Earth's surface by wearing down and moving material.
How can streams and rivers shape the Earth's surface?
Streams and rivers shape the Earth's surface through erosion and deposition. The flowing water erodes the land by carrying sediments and wearing down rocks, creating valleys and canyons. When the water loses energy, it deposits sediments, building up features like riverbanks, deltas, and alluvial plains.
Which characteristic of a transported rock would be most helpful in determining its agent of erosion?
The shape or texture of the rock would be most helpful in determining its agent of erosion. For example, smooth and rounded rocks are typically eroded by water, while angular and jagged rocks are more likely to be eroded by ice.
What is the process in which rocks change shape is called deformation deposition composition or flotation?
The process in which rocks change shape is called deformation. During deformation, rocks undergo changes in shape, volume, or orientation in response to stress. This can result in the formation of folds, faults, and other structural features in rocks.
What happens to the shape of rocks that are transported in steams?
As rocks are transported in streams, their shapes become more rounded and smoother due to the constant abrasion and collision with other particles and the streambed. This process, known as weathering and erosion, gradually chips away sharp edges and corners, leading to a more streamlined form. The extent of this shape change depends on factors such as the size of the rocks, the speed of the water, and the distance traveled. Over time, rocks can become significantly altered in shape and size as they move downstream.

What happens to a rock when it gets transported?
When a rock is transported, it can undergo weathering and erosion due to the physical forces such as wind, water, or ice. This can lead to the rock becoming smaller in size, changing shape, and eventually forming sediment. The sediment can then be deposited in a new location, contributing to the formation of sedimentary rocks through processes like compaction and cementation.

What happens to the Shape of rocks after abrasion?
After abrasion, such as being tumbled in a stream, the shape of rocks becomes smoother and more rounded. Continued abrasion can wear down sharp edges and angles, creating more rounded and polished surfaces on the rocks.
Wind and ice cause what sort of change in rocks?
Wind and ice can cause physical weathering in rocks by breaking them apart through processes like freeze-thaw cycles and abrasion. Over time, this can lead to the formation of cracks, fractures, and eventually the breakdown of rocks into smaller pieces.
How do rocks differ in shape?
Rocks can vary in shape depending on factors such as how they were formed and weathering processes. Igneous rocks may have more jagged and irregular shapes due to cooling and solidifying molten rock, while sedimentary rocks can have smoother and rounded shapes from erosion and transport. Metamorphic rocks may exhibit foliation or layering due to intense heat and pressure.
What are the three processes used to make a coastline?
The three primary processes that shape coastlines are erosion, deposition, and weathering. Erosion occurs when waves, currents, and tides wear away rocks and sediment along the shore. Deposition happens when materials transported by water are dropped, forming features like beaches and deltas. Weathering involves the breakdown of rocks through physical, chemical, or biological means, contributing to the overall landscape of the coastline.
How did water most help shape the grand canyon?
because it shape the rocks because the rocks were originally sand
What happens to rocks when its windy?
Immediately, nothing. However over long periods of time, weathering can take place. This is where the wind patterns begin to shape and carve the rock.

The shape or texture of the rock would be most helpful in determining its agent of erosion. For example, smooth and rounded rocks are typically eroded by water, while angular and jagged rocks are more likely to be eroded by ice.
