Sometimes the erosion will cut a straight path for the river to take and leave what homework help river thames used to be a bend isolated from the river. This is called an ox-bow lake.Sometimes to make it easier to for boats to travel up and down rivers, people change the way that the river flows. If part of a river is very bendy, they might dig a straighter channel for the river to flow down so that the boats dont have to make tight turns. Sometimes they make the river wider or make it deeper so that bigger boats can travel.When the river is too steep and flows to fast, they might put in locks to make it safer for the boats to travel. Rivers have also been used for a long time to help people work equipment. People would build mills to grind corn and grain near to rivers so that they could use a water wheel to work the mill.The bottom of the wheel would be put into the water, and when the water turned the wheel, the wheel would make the equipment in the mill turn and grind up the grain. Today, instead of using a wheel to operate equipment, we build big dams across the rivers and use the force of the water to turn turbines and generate electricity to power our machines. We call this hydro-electricity because it is generated from water.
How many towns in your area are named after rivers or river crossings? The Welsh word for a river mouth best statement of purpose writing service is aber. Many Welsh towns are named after the rivers that they are on, just as they are in England. Aberystwyth is town at the mouth (aber) of the river Ystwyth.The faster a river flows, the more erosion it causes in the soil and rocks around. Over millions of years streams and rivers will remove more and more material from the area around them and cut bigger and bigger paths for themselves. This is how valleys are created.Even quite small streams can create big valleys over a long time. When the slope that rivers are flowing down stops being so steep, rivers slow down and instead of rushing down the straightest path through the valley, they often start to curve and bend.These curves are called meanders. Erosion on the bends of the meanders means that they are slowly changing shape and that path the river takes will gradually change.
When a lot of rain falls in a short time, the ground cant always absorb it quickly enough. This means that lots more water than normal flows into the rivers. If there is more water than the river can carry away to the sea, it bursts over its banks and floods the land around. This is called a flash flood because it happens so quickly.There arent always many safe places to cross a river on foot, and building bridges was hard for people before they had modern machines. Anyone going on a journey would have to cross a river at the same place as lots of other people. Towns would often grow up around these places so that travellers could find a place to sleep or trade goods with each other. The mouth of a river also used to be a very good place to build a town.Large boats that cross the sea to other countries can sail into the mouth of the river to unload their cargo and to load local produce to take elsewhere. Small boats can sail up and down the river taking goods to and from the towns that are further inland.Lots of towns are named after river crossings or the rivers that flow through them. Oxford is named after a ford where people used to take their oxen across the river Thames. Stourbridge is a town in the West Midlands where there is an old bridge over the river Stour. Dartmouth in Devon is town at the mouth of the river Dart.
What is a river? A river is the path that water takes as it flows downhill towards the ocean.Rivers can be long or academic essay writing companies short, wide or narrow and they often join together on their way downstream to make bigger rivers. Lots of animals live in or by rivers and people often find them a good place to live too. Rivers can be used for lots of good things, like sailing boats on them to trade goods with other towns on the river, and farming on land that has been made fertile by the river, but when there are heavy rains and the river.
