Terminal moraine

• Moraine is a type of landform created when a glacier deposits material (Till) it has been transporting (e.g rocks from freeze thaw or plucking).
• Moraine is made up of unsorted, angular rocks.
• Terminal moraine is a ridge across the valley and made up of glacial deposits (Till) which is unsupported.
• As a glacier moves downhill it acts like a bulldozer pushing sediment in front of its snout as it goes.
• Once it reaches lower altitudes or higher temperatures, the glacier melts, loses power and deposits the moraine.
• Terminal moraine marks the furthest point the glacier reaches.
• Once the ice has retreated the Terminal moraine may form a natural dam, creating a ribbon lake.
• Add glacier formation and point of erosion (If 12 marker)
