Lesson 3 Flashcards
What are proxy records?
Data that palaeontologists gather from natural recorders of climate variability
What is geomorphology?
The study of the physical features of the surface of the earth and their relationship to its geological structure
What is lithology?
The physical properties of a rock
eg its resistance to erosion
What does lithology effect?
How quickly a coastline in eroded
What is the example for concordant coastlines?
The Dalmatian coastline in Croatia
What is the example for discordant coastlines?
The Atlantic Coastline
What is rock like on a concordant coastline?
rock is parallel to the coast
What is rock like on a discordant coastline?
Rock is perpendicular to the coast
What does less resistant rock form on concordant coastlines?
inlets or coves
What does more resistant rock form on concordant coastlines?
elongated islands
What does less resistant rock form on discordant coastlines?
bays
What does more resistant rock form on discordant coastlines?
headlands
Why is Dorest unique?
it has both concordant and discordant coastlines
south facing is concordant
east face discordant
On discordant coastlines which rock is eroded faster?
soft rock as it is exposed to the coast
On concordant coastlines which rock is eroded faster?
hard rock as it acts as a protective barrier to the softer rock behind it, when the harder rock is eroded and soft rock is exposed a cove can form
