What is a glacial sediment called? & what is a large rock transported by a glacier called?

The glacial sediment is known as glacial till.

 Glacial till is derived from entrainment and erosion of material by the moving ice of the glacier.

 It is being deposited a distance down -ice to form ground moraines, medical, lateral, and terminal. Glacial till is divided into primary deposits which are rewarded by fluvial transport.
The large rock which is transported by a glacier is called moraines. Moraines are formed from debris which is previously carried along by a glacier and consists of rounded particles which range in size from the large boulders.

 Moraines are of different types, for example, ground moraines, lateral moraines, and recessional moraine.
