It can be a liquid, a solid, or a gas. Liquid water can be fresh or saline (salty). Water moves between the places it is stored. It moves at large scales (through watersheds, the atmosphere, and below the Earth...
How much of the Earth's water is stored in glaciers?
About 2.1% of all of Earth's water is frozen in glaciers. 97.2% is in the oceans and inland seas 2.1% is in glaciers 0.6% is in groundwater and soil moisture less than 1% is in the atmosphere less than 1% is in lakes and rivers less than 1% is in all living plants and animals. About three-quarters of Earth's freshwater is stored in glaciers. Therefore, glacier ice is the second largest reservoir...

Groundwater is the source of about 37 percent of the water that county and city water departments supply to households and businesses (public supply). It provides drinking water for more than 90 percent of the rural population who do not get their water delivered to them from...

Quick Background on the Mid Atlantic region's native bees
Bees are tiny, one bush or one clump of perennials is often all it takes to foster native bees in your yard. Within a mile of your yard (urban or rural) there are at least over 100 species of bees looking for the right plants. Attracting and tending these native bees on your property is all about planting the right flowers and flowering bushes.
Introduced and Alien Bee Species of North America (North of Mexico)
Surveys by the USGS Native Bee Laboratory have uncovered several new alien bee species in the United States. The data we and our collaborators are collecting tracks the spread of these species, at least in a coarse way. We hope to expand surveys in collaboration with our federal and state land management partners as we detect more invading species. Information on distributions and status of
