Igneous Rock molten rock igneous rock is when it cools.
The rock is called a glacial erratic when it is left behind by a glacier, and is of a completely different material composition than the rocks on which it was deposited.

No, a glacier is not called a rock. A glacier is a large mass of ice that moves slowly over land due to gravity. Rocks may be found within or on top of a glacier, but the glacier itself is made of ice.

When mass from rock and soil is directly transported by a glacier, it is referred to as "glacial till." This material is unsorted and can include a mixture of clay, silt, sand, gravel, and larger boulders, all deposited as the glacier advances and retreats. Glacial till is a key feature of glacial landscapes and contributes to the formation of various landforms.
A boulder moved by a glacier is called a "glacial erratic." These large rocks are transported by the glacier as it advances and subsequently deposited in a different location when the glacier retreats. Glacial erratics can be composed of various types of rock and are often found in areas where the local geology is different from the rock type of the erratic itself.
