Bulldozing – Ice pushes material of all shapes and sizes as it moves slowly forward
The bulldozer (bulldozing) is made of ice and pushes ice and material forward.
As gravity pulls the glacier downhill the ice will slowly move, scraping and bulldozing everything in its path.
Glaciers are frozen rivers of ice which have immense power. They can carve huge chunks out of mountains as they move downhill. Some of the debris picked up by the moving glacier is piled up at the front of the moving ice and is pushed along. This is called bulldozing. You could say that glaciers are nature's bulldozers.
