The gravel and rocks frozes to a real glacier also erode the surface of the land by scraping and gouging it. Huge grooves are left in the land where moving ice has stripped the soil and dug into the rock. Many plants are helped by the snow. Snow covers plants and drifts up against tree trunks, protecting them from cold temperatures, wind, and hungry animals. The snow also covers and protects some of next year s buds, roots, and bulbs.
Plants produce something like antifreeze to survive the winter.
In late summer, plants add more sugar to their fluids, but this antifreeze is only good to about 23 degrees Fahrenheit. To protect their cells from freezing and bursting at lower temperatures, plants move water out of their cells. The area around the cells many freeze, but the actual cells are not damaged. Frogs, toads, and many insects make a similar kind of antifreeze to survive cold temperatures. In the winter, the water all around plants is frozen as snow or ice.
