L7 - Climate System Response

Question 1

Firn

Answer 1

crystallised snow, commonly on the upper part of a glacier, which has not yet been compressed into ice

Question 2

Why are glaciers on a shallow slope more sensitive than on a steep slope?

Answer 2

• slow due to less gravity influence (ice in ablation zone cannot be quickly replaced)
• lower elevation gradient (all exposed to same conditions)

Question 3

Advection

Answer 3

Horizontal movement of water with a different temperature than the surroundings. Driver: Ocean currents.

Question 4

Convection

Answer 4

Vertical movement of water. It is the rising or sinking of fluid with a different temperature (density) than the surrounding material. Driver: density differences (temperature, salinity)

Question 5

Diffusion

Answer 5

The flow of energy/matter from high to low concentration (at molecular level). Very slow.

Question 6

How can NL adapt to SLR?

Answer 6

Redesign and build delta works to reduce flood risk
