Section 2.1: A world of water

1. Where is water found in the world?

2. Why is freshwater scarce?

3. How are rivers formed?

4. How do rivers change, from source to mouth?

How many % of the Earth's fresh water is surface water?

1. 22%
2. 35%
3. 65%
4. 78%

Where can we find land ice?

1. Greenland
2. Iceland
3. Antarctica
4. The Northpole

Speak

Which colour(s) is/are not land ice?

Why is freshwater scarce?

1. 97% of the water is saline
2. Because of the Climate Change
3. It takes time to make ocean water usable
4. This is found in glaciers and ice caps

This occurs when water vapour is turned back into water droplets as it cools down:

1. Evaporation
2. Transpiration
3. Condensation
4. Infiltration

What is an effect of condensation?

1. Evaporation
2. Transpiration
3. Clouds are formed
4. Surface run-off

Which three forms of precipitation
do you know?

Speak

What is this image about?

What is the correct word for 'waterscheiding'?

1. Water separation
2. Watershed
3. Water divide
4. Watersplit

Place the key terms below the correct image

glacier valley

V-shaped valley

U-shaped valley

rivier valley

erosion by ice

erosion by a river

Section 2.2: The Rhine: a river in Europe

1. What are  the differences between the upper, middle and lower courses of the River Rhine?

2. What are the main uses of the River Rhine?

3. Why is water quality in the River Rhine an international issue?

Where is this: Some tributary rivers have joined the main river. The rate of erosion is decreasing, and there are fewer large rocks on the river bed to be eroded

1. Upper course
2. Middle course
3. Lower course
4. Of course

In which part of the river does the water flow fastest?

1. Upper course
2. Middle course
3. Lower course
4. It differs

What are the differences between the upper, middle and lower courses of the River Rhine?

Upper Course

Middle Course

Lower Course

Rocky river bed

High and steep but close river banks

A lot of erosion

Less gradient, but more river discharge

More tributaries

The river splits in three distributaries

Medium size rocks

The river moves particles it has eroded

Small rocks and sand

Teacher explains

Where does the Rhine get it's water during the summer?

1. Glaciers
2. Rainfall
3. Bottles
4. The sea

What is not a main use of the river Rhine?

1. Drinking water
2. Transport
3. Bricks
4. Hydro power

Teacher explains

How does meandering work?

What is happening here?

Speak

Old meander (oxbowlake)

Sedimentation

Lower flowrate

Erosion

Outerbend

Finish the sentence:

If the river flows fast (1) happens.
If the river flows slowly (2) happens.

1. 1 = transportation 2 = deposition
2. 1 = deposition 2 = erosion
3. 1 = erosion 2 = transportation
4. 1 = erosion 2 = deposition

Section 2.3: Dealing with water in the Netherlands

1. How are river discharges in the Netherlands likely to change in the future?

2. How does the Netherlands deal with high and low river discharges?
3. How does the Netherlands deal with extreme rainfall?

Urbanization

Growth of cities; rivers had to be tamed:

• Channelizing rivers;
• Constructing higher dykes.

In 1995 it almost went wrong...

• Evacuation of people;
• Outer-dyke areas flooded.

• Evacuation of people;
• Outer-dyke areas flooded.

Inner dyke area

outer dyke area

How does the Netherlands deal with high and low river discharges? Answer for both!

Which change has been made to give the river more space?

What change was made to the river in regard to the Room for the River project?

1. They moved the dyke
2. They made an extra channel
3. They made the dykes higher
4. They removed the groynes

De-poldering What is it?

Give the definition
of de-poldering

Most important reason to lower the groins:

1. allow the water to flow slower
2. allow the water to flow faster
3. allow the river to meander
4. allow the boats the pass each other more easily

How are river discharges in the Netherlands likely to change in the future?

1. Higher peaks of discharges
2. Lower discharges in the winter
3. The discharges will stay the same
4. Lower discharges in summer.

Section 4: The River Nile

1. What are the differences between upper, middle and lower courses of the River Nile?

2. What are the main uses of the River Nile?

3. How is population distribution in the Nile River basin linked to the Nile?

What are the differences between upper, middle and lower courses of the River Nile?

Upper Course

Middle Course

Lower Course

Name all the uses you know for the Nile

How did the Aswan Dam change the river Nile?

The uses of the river Nile

• Drinking water;
• Oppurtunity to transport goods;
• Deposited sediments made the land fertile;
• They also provided building materials.

The Aswan Dam changed the river:

• Regulating the discharge;
• Assisting in flood prevention;
• Generate hydropower; electricity generated by the flow of water.

........ of the Negro River and Solimões River, Brazil.

............ of the Danube River and Inn River, Germany.

Which keyword to these two images show?

The keyword shown

1. Delta
2. Tributary
3. Confluence
4. Distributary

How is population distribution in the Nile River basin linked to the Nile?

1. Where there is agriculture people started to build cities
2. There are more people upstream than downstream
3. Near the water the population density is high
4. The river flows to the low lying areas where the people built villages
