When rock rub against each other it is called?
When rocks rub against each other, it is called friction. This rubbing can result in the rocks wearing down over time through a process called abrasion.
What is a process when rocks rub against each other?
The process is called abrasion, where rocks rubbing against each other result in wearing down and smoothing of their surfaces due to friction and pressure. This can lead to the formation of sediments and sedimentary rocks over time.
What three things can speed up the flow of the river?
Increase in rainfall or snowmelt, leading to more water entering the river. Steeper gradient or slope along the river's path, allowing water to flow faster. Removal of obstructions such as rocks or debris that can impede the river's flow.
How is energy lost along a rivers course?
Energy is lost along a river's course through friction with the riverbed and banks, as well as through turbulence and drag caused by obstacles like rocks and vegetation. Energy can also be lost through heat transfer to the surrounding environment. Overall, these factors contribute to the gradual decrease in the river's flow velocity and energy as it travels downstream.
What is A displacement between two bodies of rock is called?
A displacement between two bodies of rock is called a fault. This occurs when there is movement along a fracture in the Earth's crust, resulting in the rocks on either side shifting relative to each other.
What are small rocks carried along by a river called?
sediment
What is the transportation that drags large rocks along the river bed called?
dredging?
What large boulders carried along by a river?
Large boulders and smaller rocks can be carried by a river. When rocks and sediment are displaced, it's called erosion.
Why does most erosion occur along the bottom of the river?
rocks are there
What is a river's load?
material that a river carries along E.g (stone, grass & rocks)
What is weathering of rock caused by solid particles hitting or rubbing against them called?
The process of weathering caused by solid particles hitting or rubbing against rocks is called abrasion. This physical process can gradually wear down the surface of rocks over time, leading to erosion and a change in their appearance.
What is a break or crack along which rocks moved called?
A break or crack along which rocks move is called a fault. Sudden motion along the faults result to earthquakes.
How do river valleys form?
A river creates a canyon through erosion. The faster the water is moving the faster the canyon is going to be formed. The water rushes on the bottom and moves rocks as it goes along and the rocks scrape on other rocks and loosen up the soil and other rocks so it carves out a canyon.
What are dirt rocks or sand carried by a river called?
deposition
What is the movement called that bounces rocks on the river bed?
Saltation-smaller rocks and stones. Traction-larger rocks and boulders.
When rock rub against each other it is called?
When rocks rub against each other, it is called friction. This rubbing can result in the rocks wearing down over time through a process called abrasion.
How can large rock be transported in a river?
Large boulders and smaller rocks can be carried by a river. When rocks and sediment are displaced, it's called erosion.
