Glaciers chisel away the land like a rake
Like a rake scraping the dirt, glaciers leave a lasting impression on the land.
During the last ice age, glaciers scraped away Canadian rock dumping most of it the northern United States.
They tore mountains down carrying vast amount of rocks from the continent across the border.
Continental glaciers chisel away at the land leaving its fingerprint in the land.
For example, Long Island, New York is the result of glacial debris from the sediment dumping of a glacier terminal moraine.
