What is the plan for today?

C3.3: Water: Protecting the coast

C3.3: Water: Protecting the coast

GOALS OF LAST LESSON

1. You know 2 reasons why the sea levels are rising.
   
2. You can explain the definition of relative sea-level rise.
   
3. You know 3 reasons for subsidence in the Netherlands.

You know 2 reasons why the sea levels are rising.

1. Climate change

2. Subsidence

• See next slide

         "The bottom sinks"

SUBSIDENCE

during/after the last ice age

You know 3 reasons for subsidence in the Netherlands.

1. "Seesaw" after the last ice age.
2. Pumping away rising groundwater.
3. The extraction of "minerals".

You can explain the definition of relative sea-level rise.

CHECK HOMEWORK

TODAY'S GOALS

1. You are able to explain how a polder works.
   
2. You can explain how sand suppletion is used to strengthen the coast.
   
3. You know the differences between glacials and interglacials.
   
4. You can explain relation between the decreasing of ice and the albedo effect.
   

You are able to explain how a polder works.

Read "Below sea level" in your coursebook.

Open page 84-85 in your GeoGuide.

Below sea level

Polders - Areas of land where water levels are controlled by man-made methods.

THE POLDER SYSTEM

THE POLDER SYSTEM

Sand suppletion - Putting a lot of extra sand along the coast to protect against rising sea levels.

Let's go!

• Read C3.3: Energy in the future
•  Use G86: Ice ages
• Make 1, 3, 4, 5 & 6

Rules while working:

• You are allowed to work together
• Raise your finger if you have a question
