Which best describes the process for how a glacier is formed?
Snow falls from the sky and freezes
Snow falls over and over again freezing what is underneath it. This causes the layers to get deeper. Once it becomes heavy, it begins to slide downhill and spread out.
Rain must fall 3 days in a row and then the temperatures drop below freezing. This causes the rain to freeze and turn into ice.
Which of these is NOT an effect of glaciers on Earth?
Glaciers make the water levels rise which causes floods in many areas.
Glaciers grind away at the Earth.
