Key Terminology
Ablation: output of water from a glacier as the ice melts.
Abrasion: eroded rocks picked up by the river scrape and rub against the channel wearing it away.
Accumulation: input of snow and ice into a glacier.
Attrition: eroded rocks iced up by the river smash into each other and break down.
Biological weathering: plants and animals cracking the rock.
Chemical weathering: when weak acids in the rain water breakdown rock surfaces.
Erosion: wearing away of the land by water, ice and wind.
Extrusive rocks: rocks formed from magma on the Earth's surface.
Freeze-thaw weathering: takes place when water is trapped in the cracks of a rock.
Geological timescale: this shows time periods from the past 4.6 billion years.
Glacier: a mass of ice that moves very slowly downhill.
Glaciation: formation of glaciers and the process by which they shape the landscape.
Glacial budget: difference between total accumulation and total ablation for one year.
Hydraulic action: the force of water breaking rock particles away from the river channel.
Igneous rock: rocks that are formed from molten lava. An example is Granite.
Intrusive rocks: rocks formed inside the Earth.
Impermeable: does not let water pass through. An example being clay.
Lithification: process of compactment
Metamorphic rock: these are existing rocks that change under intense heat and pressure. An example is marble.
Moorlands: large areas of waterlogged and acidic soil.
Onion-skin weathering: when rocks expand and contract in the what causing later to peel off.
Permeable: lets water pass through. An example is limestone.
Physical (mechanical) weathering: weathering by physical factors such as wind, rain and weather.
Porus: can be penetrated by water
Pucking: occurs when meltwater under the glacier freezes on the rock's surface.
Retreating glacier: result of increasing temperatures causing ice to melt.
Rock cycle: a cycle that shows how rocks are formed.
Sedimentary rock: rocks that are formed when different fragments are compressed together. An example is sandstone.
Solution: river water dissolves some types of rock in the river.

Teaching and pedagogy:
Terminology dominos: To test simple definitions
All students are given a card similar to the one below.
Terminology dominos: To test simple definitions
All students are given a card similar to the one below.
The teacher should start by reading a key word. The student who has the definition to this word on their card should read it allowed and then read the key term at the bottom of their card. Then, the student who has the definition to this key word should read it allowed and read their key word. This should continue until all students have read their definitions and the teacher should have the last definition to complete the game.
