Glossary Check out the pronunciation, synonyms and grammar. Therefore, ice thermal energy storage systems could be better understood by understanding these characteristics. Glacial till is the sediment deposited by a glacier. - it is left behind as the glacier advances. Lodgement till is material deposited by moving ice such as ground moraine which is dropped by the glacier when its weight becomes too heavy to move. Ablation till also contains a wide variety of grain sizes, but it is much sandier and looser than lodgement till. 0000053172 00000 n The ablation till grades into the lodgement till and mapping Terminal, push and recessional moraine.
