Surface Processes: Moving Water
Learn about the importance of wet and dry seasons in wetland ecology. Students will learn to understand the wetlands as precious ecosystems.
Explore how the slope of land will effect water flow and life above ground in this activity from the Soil Science Society of America.
Water that accumulates beneath the surface of the Earth is called groundwater. Contrary to popular belief, groundwater does not form underground "rivers," but is actually found in the small spaces and cracks between rocks and other material such as sand and gravel. The following activity involves learning how water moves through rock materials such as sand, gravel, and clay.
Groundwater on the Move
The following activity involves learning how water moves through rock materials such as sand, gravel, and clay.
How Dangerous Are Tsunamis?
Imagine playing beside the ocean, when suddenly, the water drops. Where the water used to be, there are wriggling fish and ribbons of seaweed. What do you do?
Humans and Water, Past to Present
Humans use lots of water. We need it for various activities, including agriculture, transport, washing, and recreation. Most important, we need to drink fresh water to stay alive. Today, in many regions around the world, fresh water comes straight to where we need it. But in some places, people must carry gallons of water from the closest stream, river, lake, or well to their homes.
Identifying Your Watershed
The goal of this activity is to identify the watershed you live in, the source of water you use at home and the pathway of surface water runoff in your watershed.
It's About Time
Geologic time can be difficult for people to understand. Our own lives are so short when we compare them to the age of the Earth, that the hundreds of millions of years of geologic time are almost too much to grasp. To understand how a timeline works, you will make a personal timeline and compare it to the geologic timeline shown here.
Model of a Well
Groundwater is contained in the zone of saturation below the land surface. The top of this zone is known as the water table. People can tap into this source of water by drilling wells. The depth of the well and level of the water table greatly influences the wells productivity. In this activity you will demonstrate the relationship of groundwater to wells.
