What is the water cycle?
100
Mountain bogs collect rainwater and create the start of a river.
What is the source of a river
100
The water on Earth today is the same water that was here millions of years ago.
What is true
100
The liquid and solid water particles that fall from clouds and reach the ground are known as __________. These particles include drizzle, rain, snow, snow pellets, ice crystals, and hail.
What is precipitation?
100
a winding curve or bend of a river or road.
What is a meander?
200
An instrument used to measure temperature
What is a thermometer
200
Where the river meets with the ocean or sea.
What is the mouth/estuary?
200
Floods are not a constant threat and can be prevented.
What is false?

_________ is the process by which water changes from a liquid to a gas or vapor. Also, the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.
What is evaporation
200
the gradual destruction or diminution of something.
What is erosion
300
Water that runs off the land to lower places
What is runoff
300
Where two rivers meet.
What is a tributary?
300
A liquid will change to a solid when heat is added.
What is false
300
__________is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor.
What is condensation.
300
The _________of a river has more energy and volume then in the upper course. The gradient is more gentle and lateral (sideways) erosion has widened the channel. The river channel has also become deeper. Meanders are typical landforms found in this stage of the river.
What is the middle course
400
_________ is the processes where material being transported by a river is deposited. Deposition occurs when a river loses energy. This can be when a river enters a shallow area (this could be when it floods and comes into contact with the flood plain) or towards its mouth where it meets another body of water
What is deposition?

This river is a main water source in the continent of Africa. 95% of the population in Egypt live by the this river. Ancient Egyptians developed ways to bring the water from this river onto the land to use for their crops.
What is the Nile River?
400
Water is constantly moving and changing from one form (liquid, gas, solid) to another.
What is true
400
the draining away of water (or substances carried in it) from the surface of an area or land.
What is runoff?
400
The volume of water in a river is at its greatest in the _________. This is due to the contribution of water from tributaries. The river channel is deep and wide and the land around the river is flat. Energy in the river is at its lowest and deposition occurs.
What is the lower course
500
__________ is the process by which water on the ground surface enters the soil. Infiltration rate in soil science is a measure of the rate at which soil is able to absorb rainfall or irrigation. It is measured in inches per hour or millimeters per hour.
What is infiltration?
500
When erosion causes banks to form in the river and they create a bend along the river.
What is a meander?
500
Water that comes from a cloud and falls as rain, snow, sleet or hail is called run-off.
What is false. These are forms of precipitation.
500
They are saturated with water for most of the year, and many have thick layers of moss and mud
What is a mountain bog?
500
As the river moves through the __________it cuts downwards. The gradient here is steep and the river channel is narrow. Vertical erosion in this highland part of the river helps to create steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges.
