Rain and moving water in oceans, rivers , and streams can erode even the hardest stone over time. Rain water that works its way to streams and rivers picks up and moves soil and sand.These particles make the river water similar to a giant scrub brush that grinds away at river banks and ANY other surface in the water's path.

What else can I help you with?
Why do you need erosion and weathering?
Erosion and weathering help to break down rocks and minerals, contributing to the formation of soil. This process also helps shape the Earth's surface by creating landforms such as valleys, canyons, and cliffs. Erosion and weathering play a crucial role in the natural cycle of Earth's geology.
What roles does water play in cave formation?
Chemical weathering, esp. in carbonate rocks, aided to some extent as the conduit develops by mechanical erosion by the stream.
What processes impact all of earth's land features and play a part in creating new rocks?
Folding and banding
What are the agents of weathering and erosion?
Some agents of weathering are heat from the sun, plant and animal activity, freeze-thaw cycles, abrasion from windblown ice or water carried material, chemical weathering from acidic solutions such as acidic rain, and hydrolysis. The four main weathers agents are wind, ice, gravity, and water.The agents of weathering include temperature, water, and gravity. Water causes the most weathering with ice, rain, and river movement causing stone to weather.
What is surface geologic process?
Surface Geologic Processes also reffered to as, Exogeneous Geologic Processes, are the processes that operates on the Earth's surface and helps to reconstruct the Earth externally. They include, Erosion, Weathering, Mass Wasting, Orogeny. Their agents are called the Epigeal Geological Agents, and include, Wind, Water, Glacier, Waves etc.
What basic part does weathering play in the erosion process.?
It breaks rock into smaller pieces that are more easily moved by the agents of erosion.
How do living and nonliving things impact the process of weathering and erosion?
Living things impact weathering and erosion by contributing to the breakdown of rocks through processes like root wedging and burrowing. Nonliving factors such as water, wind, and temperature fluctuations also play a significant role in weathering and erosion by physically breaking down and transporting rocks and sediments. Together, these factors shape the landscape over time.
Are valleys formed by weathering and erosion?
Yes, valleys are primarily formed by a combination of weathering and erosion processes over time. Weathering breaks down rocks into smaller particles, while erosion transports these particles away, often carving out valleys in the landscape. Factors such as water, wind, ice, and gravity all play a role in shaping valleys through weathering and erosion.
How are floods relate to weathering erosion and deposition?
Floods play a role in weathering, erosion, and deposition by carrying and transporting large amounts of sediment and rocks. During a flood, erosion occurs as flowing water removes and transports material. Deposition happens when the water slows down, causing sediment to settle. Overall, floods can accelerate the processes of weathering, erosion, and deposition by moving and redistributing Earth's materials.
Why do you need erosion and weathering?
Erosion and weathering help to break down rocks and minerals, contributing to the formation of soil. This process also helps shape the Earth's surface by creating landforms such as valleys, canyons, and cliffs. Erosion and weathering play a crucial role in the natural cycle of Earth's geology.
What role does wind and water play for sedimentary rocks?
weathering and erosion helps to build sedimentary layers then sedimentary rocks
What is the agent of erosion?
The agent of erosion is a natural force or process that wears away the Earth's surface, such as water, wind, glaciers, or waves. These agents play a crucial role in reshaping the landforms over time through processes like weathering, transportation, and deposition.
Which factor does not play a role in both weathering and erosion?
Chemical composition of the rock does not play a role in erosion, as erosion is primarily driven by forces like water, wind, and ice that physically wear down and transport rock particles. In weathering, factors such as temperature, moisture, and type of vegetation can contribute to the breakdown of rock material.
What is the effect of weathering and erosion on the topography of an area?
Weathering and erosion can smooth out rugged mountains, carving valleys, canyons, and cliffs over time. As rocks are broken down and carried away by weathering and erosion processes like wind, water, and ice, the landscape can be reshaped and flattened. Overall, weathering and erosion play a key role in shaping the topography of an area by gradually changing the landforms present.
What process within the rock cycle operates at the earth's surface?
Weathering and erosion are processes within the rock cycle that operate at the Earth's surface. Weathering breaks down rocks into smaller pieces, while erosion involves the movement of these sediments by water, wind, ice, or gravity. These processes play a key role in reshaping the Earth's surface over time.
Does chemical weathering cause erosion in Florida?
Chemical weathering can contribute to erosion in Florida, but it is not the sole cause. Florida's sandy soils are particularly prone to erosion due to their loose nature, along with factors like rainfall, storms, and sea-level rise. Chemical weathering can weaken rock and contribute to the erosion process, but other factors play significant roles as well.
What role does gravity play on weathering?
Gravity contributes to weathering by pulling materials downhill, increasing the force of weathering processes such as physical erosion and mass wasting. Gravity also influences the movement of water and ice, which further aids in the breakdown of rocks through erosion. Overall, gravity plays a crucial role in shaping landscapes through weathering processes.
