key definitions

Question 1

estuarine coastline

Answer 1

-extensive mud flats
-cut by channels exposed at low tide
-closer to the backshore the mudflats are vegetated forms salt marsh

Question 2

low wave energy

Answer 2

-sheltered coasts with limited fetch and low wind speeds
-results in small waves

Question 3

high wave energy

Answer 3

-exposed coasts
-facing prevailing winds with long fetches resulting in powerful waves

Question 4

primary coastlines

Answer 4

-dominated by land-based processes such as deposition at coast from rivers

Question 5

secondary coastlines

Answer 5

-dominated by marine erosion or deposition processes

Question 6

emergent coasts

Answer 6

-where coasts are rising relative to sea level
-due to tectonic uplift or isotatic rebound for example

Question 7

submergent coasts

Answer 7

-being flooded by the sea
-could be due to rising sea levels and/or subsiding land

Question 8

microtidal

Answer 8

-tidal range of 0-2m

Question 9

mesotidal

Answer 9

-tidal range of 2-4m

Question 10

macrotidal

Answer 10

-tital range greater than 4m

Question 11

erosion resistance

Answer 11

-how hard the rock is
-how reactive minerals in the rock are when exposed to chemical weathering
-the degree to which the rocks have cracks, fissures and fractures

Question 12

clastic rock

Answer 12

-sedimentary, made of cemented sediment particles

Question 13

resistant crystalline rock

Answer 13

-igneous/metamorphic made of interlocking crystals

Question 14

geological structure parts

Answer 14

-strata
-deformation
-faulting

Question 15

what can sediment supply include

Answer 15

-eroding cliffs
-tidal currents
-rivers
