What is an Arete?-This is simply a very Narrow, Steep-Sided Ridge -Formed when 2 Glaciers flow in Parallel Valleys, which will Sharpen the Ridge due to Erosion Processes -Example may be in Striding Edge, Lake District
What is a Corrie? [Cirques]-This had its Life begin as a Hollow with a Small Glacier -Because of Rotational Slip, it then becomes a Steep-Sided Armchair shape, that has a sort of Lip in the Bottom End -A Tarn can often be left there, which is simply a Lake. That's it -Example may be Red Tarn, Lake District
What are Ribbon Lakes?-This is simply a Long Thing LAKE -Formed when the Glacier retreats up, and also in Hollows where the Softer Rock has been Eroded More -Example may be Windermere, Lake District
What is a Pyramidal Peak?-This is simply a Mountain Peak with it having 3+ Sides. -Formed when 3 Glaciers, or More, back to back, Erode a Mountain -Example may be Snowdon, Snowdonia

What is Medial Moraine?-This is simply Material that is Deposited on the Central Line of where the Glacier once stood -If 2 Glaciers do Meet, then the Lateral Moraine from the Edges that are Joining up will become the Medial Moraine for the New Bigger Glacier
What is Terminal Moraine?-This is simply Material that is found at the Snout [Front] of a Glacier -This is used for a Marker for where the Ice had Reached, in which the Material there has been Plucked and Abraded has been Dropped as Semi-circular Mounds, when the Ice Retreats
What is Ground Moraine?-This simply is Material that is Dragged along the Base of the Glacier -Material here, is dropped over a Large Area on the Valley Floor
What are Drumlins?-This is simply a Hill that is Unbalanced in its Steepness -It is Formed [Not Always] when either the Glacier is Overloaded or Melted and is therefore Depositing Material, which ill then make a Hill -As the Ice Flows over the Hill, the Shape of the Hill also will Change, making it more Steep in Upper Course of the Glacier, and then more Sloppy in the Lower Course of the Glacier -Example may be in Wisconsin USA
What are Erratic's?-This is simply a Rock that has been Carried by the Glacier and been Dropped in an Area which has a Completely Different Rock Type. -Just Rocks out of Place, that's it
