Brooks (2011) Flashcards

(10 cards)

1
Q

What is the main focus of Brooks et al. (2011)?

A

Reconstructing the palaeogeography of Northwest Europe over the last ~20,000 years, especially the effects of relative sea-level rise on landscapes.

Q

What are the two main drivers of relative sea-level change in NW Europe?

A

Eustatic sea-level rise (melting ice sheets)
Isostatic land movement (uplift/subsidence)

Q

What is glacio-isostatic adjustment, and why is it important?

A

The vertical movement of land after ice-sheet loading/unloading; it causes uplift in formerly glaciated areas and subsidence elsewhere, affecting relative sea level.

Q

Why does relative sea-level rise differ spatially across NW Europe?

A

Because different regions experience different combinations of uplift (e.g. Scandinavia) and subsidence (e.g. southern North Sea basin).

Q

What was Doggerland, and what happened to it?

A

A low-lying landmass in the North Sea connecting Britain to mainland Europe, gradually flooded due to sea-level rise after the last Ice Age

Q

How did sea-level rise affect river systems in NW Europe?

A

Rivers shifted from deeply incised valleys to more sediment-filled, low-gradient systems as base level rose

Q

Why is the Holocene coastline of NW Europe highly dynamic?

A

Because of the interaction between sea-level rise, sediment supply, tidal processes, and human influence

Q

How did relative sea-level rise impact human populations?

A

It led to loss of habitable land, forced migration, and changing settlement patterns (e.g. retreat from lowlands, adaptation to wetlands).

Q

Why is understanding past sea-level rise important for today?

A

It provides analogues for future climate change impacts, especially for low-lying coastal regions like NW Europe.
