Uk's physical geography
Igneous
Igneous rocks are formed by magma from the molten interior of the Earth. When magma erupts it cools to form volcanic land forms. If magma cools inside the Earth it forms intrusive rock , which may later be exposed by erosion and weathering.
Metamorphic
The addition of heat and/or pressure to existing rocks, which causes them to change physically and/or chemically so that they become a new rock.

Impermeable rocks
Some rocks have pores in them, which are empty spaces. ... However, if the pores are not linked, then no liquid, for example water, can flow through the rock. When the pores are not linked, the rock is impermeable.
scarps
A scarp is a) a line of cliffs produced by faulting or b) low steep slope along a beach caused by wave erosion

Abrasion
this is when pebbles grind along a rock platform, much like sandpaper. Over time the rock becomes smooth. Attrition - this is when rocks that the sea is carrying knock against each other. They break apart to become smaller and more rounded.
Moraine
A moraine is material left behind by a moving glacier. This material is usually soil and rock. Just as rivers carry along all sorts of debris and silt that eventually builds up to form deltas, glaciers transport all sorts of dirt and boulders that build up to form moraines.
Corrie
A corrie is a horseshoe-shaped valley which is formed through erosion by ice or glaciers. Corries are north-facing, away from the sun which stops the ice from melting. As snow and ice build-up, the underlying rock is eroded
Plucking
Plucking occurs when rocks and stones become frozen to the base or sides of the glacier and are plucked from the ground or rock face as the glacier moves
U shaped valley
steep sides and a wide, flat floor. They are usually straight and deep. They are formed in river valleys which, during the ice age, have been filled by a large glacier . These glaciers have deepened, straightened and widened the valley by plucking and abrasion.
