Answer
The river current starts wearing down the rocks in its path or on its banks. Small fragments of the rocks break off and are carried down-river. This process proceeds very slowly and usually takes many many years (thousands) for an appreciable quantity of the rock to get eroded. Answer Much depends on the speed of the water that is moving in the river. Fast moving streams and rivers when flooding can cause the movement of huge boulders. Slow moving waters can only carry suspended fine particles. Erosion refers to the moving of particles from one place to another place. Moving water provides the force necessary to move those particles and is responsible for the bulk of erosion that takes place on the planet.
River drops its load in the middle and later stage of its flow. Hence the features like ox-bow lake are found in the middle stages and deltas are found at the mounth of river. Whereas in the early youth stage its main action is in erosion.
sediment, and once that material is dropped, its called deposition.
When a river drops material it is carrying?
...it forms a delta.
The process by which rivers lay down material they are carrying is called deposition. Deposition takes place after erosion and transportation of material by the river.
in solution, in suspension, and in its bed load.
saltation and suspension
They go with the flow.
Active transport and passive transport.
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
endoplasmic reticulum
Transport
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
Gymnosperms transport materials through vascular tissues.
Usually it was because the rivers were used to transport materials and goods. Saw mills were very popular way back then and many cities grew around the mills because that was were the work was. They used the rivers to float the logs and ships to transport other things. Eventually railways were used in the same way, and then of course trucks.
Cities in Europe are located at the banks of rivers because the people use the rivers as transport routes to transport goods from place to place
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
Active transport and passive transport.
Before roads rivers canals etc where used to transport goods.the boats was easier transport than animals holding more goods aboard.
They sendit through lakes.
Drinking water, fishing and transport.
the lysomes if not what else
Water is an easy way to transport of food, materials, etc. Rivers, lakes and streams are also sources of drinking water - and provide for agricultural needs.
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
Similarities : used in circulatory system, transport materials, differences : arteries are thicker, and used to transport materials to the cells veins are thinner, and used to transport materials from the cells to areas of the excretory system.
