Rivers and Streams
River Characteristics
Sediment and sediment made characteristics
100
Water that doesn’t sink into the ground or gets evaporated, it runs on land and causes sheet erosion
What is Runoff
100
A _________ is a high area of land the separates two drainage basins
What is divide
100
Waterfalls, oxbow lakes, meanders and floodplains
What are the four main characteristics made from a river that erosion makes
100
What the particles are called that a river carries with it, this can also be left behind after floods and will sometimes sink to the bottom of a river
What is sediment
200
The first is how steep the gully or hill is The second is how much vegetation an area has The third is the type of soil The fourth is how much rain an area gets The fifth is how we use the area of the land
What are the 5 factors to determine how much runoff changes the environment
200
A _________ _______ is where the river and the tributaries collect their water
What is a drainage basin
200
These start being formed when softer rock starts eroding and the harder rock before it stays, then it erodes so much that it makes a __________
What is a waterfall
200
A delta is where the river reaches a ocean or lake and stops flowing and once it stops the sediment builds up to make the delta which could be a variety of shapes
What is a delta
300
This is water that doesn’t sink into the ground or gets evaporated, it runs on land and causes sheet erosion
What is runoff
300
Some of the time a stream will grow larger or into a river by receiving more water from a ________ A ________ is a stream or river that runs into another river or stream so the ________ can give the river or stream more water
What is a tributary
300
A _______ occurs when the rivers flow less downward and the river expands into a flat wide area that can be flooded easily
What is a flood plain
300
After a river keeps going after a high decline it will slow down and form an ______, it is made by sediment being deposited in a area
What is an alluvial fan
400
Small grooves in the soil that is caused by the runoff water getting pulled into the ground by gravity and erosion by runoff
What is a rill
400
When gullies get even bigger and collide to connect more they make _______, _______ are long narrow paths for water to travel on and barely dry up because they can hold so much water
What is a Stream
400
A _______ is where the river starts to curve because it is eroding more of one side and not the other and doing the same on the other side
What is a meander
400
The _______ _____ ________ of a particle or rock is, the faster it would sink and ___ ______ __ _____ of a rock or particle is, the slower it will sink
What is the higher the density of a particle or rock is, the faster it would sink and the lower the density of a rock, or particle is, the slower it will sink
500
When rills get larger they are called _____ and they will get bigger and bigger because of all the runoff eroding it more and more
What is a gully
500
When streams get even bigger and bigger they are called ______which tend to be longer and hold more water
What is a river
500
An _______ is where a meander isn’t receiving any water because the other part of the river goes another way
What is an oxbow lake
500
The more ______ and _______ rock or particle is, the more likely it will sink because the _______ and _______ rocks tend to get more resistance from the water and stay afloat
What is the more circular and bigger a rock or particle is, the more likely it will sink because the oval-ish and smaller rocks tend to get more resistance from the water and stay afloat
