At the confluence of a river mouth and the ocean/sea
How are fjords formed?
The submergence of a glacial valley after a marine transgression; it’s now occupied by a deep inlet of sea
What is the name given to lithified tills?

Hoodoos or Fairy chimney
Which 2 agents are not influenced by climate?
Seas and oceans, groundwaters
Name 3 tools valley-alpine glaciers have…
Ice rubs and polishes rocks, Angular sediments are carried down the valley and they rub against walls, Freezing of melted water pulls pieces of rocks
In which relief does water accumulate in aquifers?
Groundwaters
What are the characteristics of this landform: Upper course
Narrow V-shaped valleys Gorges, cascades and waterfalls
Give 3 examples of soft and homogeneous terrains…
Grooves, Gullies, Ravines
What reliefs do seas and oceans shape due to sedimentation?
Beaches, barrier spits and barrier islands, Cove, Coastal lagoon, Tombolo
What happens due to erosion?
Cliffs and abrasion platform, Capes and gulfs or bays
How can you define 'River'
It's a large and permanent flowing body of water which runs down a fixed channel
What reliefs do fast-flowing water shape?
Grooves, Gullies, Ravines, Hoodoos, Fairy chimney
What are the characteristics of this landform: Soft and homogeneous terrains
Grooves, Gullies, Ravines
What are the characteristics of this landform: Alluvial fan
Fan shaped foothills
Where does the water come from in fast flowing water formations?
Water comes from torrential rainfall and melting ice.
What are the characteristics of this landform: Middle course
Wide V-shaped valleys Meanders
Why is water scarce in the desert?
Because they are areas of infrequent precipitation and high evaporation; so water is scarce and dry materials are easily displaced by the wind
What reliefs do valley-alpine glaciers shape?
U-shaped valleys, Amphitheater-shaped cirque, Mountain peaks, Striations on the rocks, Sheep-shaped rocks, Accumulation of tills, Glacial lakes
Are seas and oceans influenced by climate?
No
Where does groundwater run through?
Permeable rocks
What reliefs do seas and oceans shape due to erosion?
Cliffs and abrasion platforms, capes, gulfs, bays
What reliefs does wind shape?
Desert areas are distributed into concentric zones: e.g. Dunes, Oasis, Wadis, Loess deposits, Arches and holes in rocks, Mushroom-shaped pillars
How can you define 'Fast Flowing Waters'
Streams of water which run down a hill thanks to gravity, without a fixed channel
Name 3 tools the ocean have…
Strength of waves, Dissolution of mineral salts, Marine abrasion (particles are thrown against rocks as projectiles), Marine currents transport and sediment mat
Name 3 tools rivers have…
Water strength Water speed - according to the steepness Particles carried out by water
How can you define 'Torrent'
Short and irregular streams of water which run a fixed channel in steep mountainsides
Which characteristics do these belong to: dunes, oasis’ and wadis’?
Wind
Name the 3 parts of a glacier…
the cirque (accumulation zone), the ice tongue and the glacier terminus
Are dunes static? Justify your answer
Dunes can move! They aren’t fixed, on the contrary, they are displaced by changing wind direction.
Name 3 tools groundwaters have…
Carbonatation, Water strength, Particles carried out by water
What are the characteristics of this landform: Basin
