uplands
land that is hilly or mountainous
foreground

land use
what land is used for, e.g. farming or industry
physical layer
where geology and landscape processes (erosion, weathering, etc.) have sculpted a landscape
biological layer
soil, plants, and trees
human layer
settlements, communications, and farming
geology
the study of rocks beneath our feet
erosion
the wearing down of rocks that have already been weathered or broken
weathering
the process that takes place which breaks the geosphere into smaller pieces

gryke
a deep crack in the surface of limestone
clints
limestone blocks separated by deep cracks (grykes)
vegetation
plants
hydraulic erosion
power of the water breaking apart the rock
abrasion (erosion)
stones and sediments grind against the rock like sand paper
attrition (erosion)
rocks in the water breaking each other apart
solution (erosion)
chemicals/ liquid dissolves the rock
freeze-thaw weathering
the weathering of rocks re-freezing and thawing from rainwater
corrie
a highland with round slopes, a U-shaped valley (made by glaciers)
scree
small loose stones made by freeze-thaw weathering
tarn
a small mountain lake
glacier
a river of ice, usually occupying a valley
ice sheet
a large layer of ice several kilometres thick
MSL
Mean Sea Level
ways that height on a map can be shown (MSL)
black dot (spot height), triangulation pillar, layer colouring/ shading
