The attached PowerPoint is an introduction to thermal stratification and turnover in lakes, and interpretation of temperature profile data. The stand-alone presentation can be used to complement a lesson in Earth Science.
Glaciers are slow-moving masses of ice that exist where more snow falls than melts. They occupy about 10% of the Earth’s land, mostly in Greenland and Antarctica. Here, glaciers can be as much as 2 miles thick and weigh more than millions of tons. As they move, glaciers can widen and deepen valleys, flatten forests and grind boulders

Other scientists are thinking of ways to limit the amount of sun that reaches Earth so that the Earth won’t get so warm. Like most ideas, there are pros (good
A link to the Young Explores Grant and Program. Today, Young Explorers grants help cover field project costs for hard-working, passionate, creative individuals with great ideas. We focus on the disciplines we're known for, and also on emerging fields that matter most to understanding—and improving—the world we share.
