  • uplands & lowlands landscapes
    • KEY WORDS
      • marshlands ~muddy wet land
      • relief ~ how high or low the land is.
      • eroding / erosion ~ to ware away
      • glacier~is a river of ice
      • glaciation ~prosses of aglacier eroding the land
      • wethering ~ the breakdown of rocks
        • chemical weathering~caused by numerous things both living and physical. it changes the chemical state
        • physical wethering~ caused by allthe weather and moving water;it dosn't change the chemical stae of the rock
    • LOWLANDS
      • found in the south and the east  of the uk .
      • around the wash (east anglia and lincolnshire)
      • rock type found there is sedimentary which is permeable
      • The term "bottomland" refers to low-lying alluvial land near a river.
      • Untit lowlands was formed by eroded material of the shield that was deposited by the seasled
      • Structural plains tend to be large flat surfaces that make up extensive lowlands.
    • UPLANDS
      • is generally considered to be land that is at a higher elevation

      • Wales - Snowdonia and the Brecon Beacons. Snowdon is the highest mountain in Wales and is found in Snowdonia.
      • found in the north and the west of the uk .
    • weathering and the river alley
      • wethering ~ the breakdown of rocks
        • chemical weathering~caused by numerous things both living and physical. it changes the chemical state
        • physical wethering~ caused by allthe weather and moving water;it dosn't change the chemical stae of the rock
      • chemical weathering
        • the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions
        • Rainwater and seawater can be a weak acid.
        • Over time a coastline made up of rocks such as limestone or chalk can become dissolved by the acid in the water.
      • freeze thaw
        • There are two main types of physical weathering:Freeze-thaw
          • Untitl occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.ed
      • biological weathering
        • Plants and animals can have an effect on rocks.
        • Roots burrow into the rock, weakening the structure of the rock until it breaks away.
