Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation.
The United Nations includes clean water and sanitation in its sustainable development goals. Many places face severe water shortages. The Geoscientists Without Borders® (GWB) program supports teams to collaborate with communities to solve problems, including water shortages.
GWB scientists use geophysical techniques to find underground layers of sediments or rock that contain enough water to be drilled for water wells. These kinds of rock layers are called aquifers. In this activity you will build a model aquifer.
Soils are a key component of the interface between the biosphere (life) and the geosphere (land). Soils support life.“Our soils support 95 percent of all food production, and by 2060, our soils will be asked to give us as much food as we have consumed in the last 500 years,” according to Living Soil by The Soil Health Institute.
You may be familiar with ice cubes in your favorite soda, but do you know there are very big ice cubes (scientists call them glaciers) hundreds to thousands of meters thick, lying in places
with high mountains? These glaciers shaped beautiful landscapes all around the world — from Glacier National Park to Yosemite, from Patagonia in South America to the Himalayas in Asia.
Composting is the decomposition of organic waste materials in the presence of water, air, and microorganisms to produce organic fertilizer. Organic matter improves soil quality by feeding soil organisms, provides plants nutrients for growth, and enhances soil structure and water holding capacity., while reducing our dependence on synthetic fertilizers.
Wetlands are places where the water table is usually at or near the surface or the land is covered by water or saturated at least some of the time. They include mangroves, marshes, swamps, forested wetlands, and bogs and are important nurseries for young birds, fish, amphibians, and other aquatic plants and animals. In addition to providing habitat for wildlife, wetlands offer storm protection, improve water quality, support aquatic species, and provide recreational opportunities.
