Question

Quizplus · Accepted Answer

Till is an unconsolidated mixture of glacial sediment ranging in size from clay to boulders, and it is unstratified, meaning the sediments are not arranged in any particular order or pattern. Stratified drift is a type of glacial sediment that is layered, and it is typically found in glaciofluvial deposits. Ground moraine forms under a glacier and is composed of unsorted and unstratified debris that has been ground up by the ice. Lodgment till is formed when the glacier is frozen to the underlying bedrock and incorporates debris into the ice. Ablation till forms from material dropped by melting ice.
