Why do hard surfaces cause more flooding?

Roofs, roads and parking lots stop rain from soaking in, so water runs quickly into storm drains and streams rise faster and higher. Pavement Cover and Storm Runoff Data has students graph peak flow against percent hard surface for six watersheds. They then predict how much rain gardens, permeable pavement and a retention pond would help.

What causes global wind belts?

The Sun heats the equator most, so warm air rises there and sinks near 30 degrees, forming the Hadley cell. Ferrel and polar cells complete the pattern, and Earth's spin turns the surface winds into the trade winds, westerlies and polar easterlies. Label Global Wind Belts and Circulation Cells covers all of these.

How can you tell when a cold front has passed?

Temperature and dew point drop, pressure falls to its lowest point and then rises, and the wind shifts to the northwest. A short burst of heavy rain often falls. Find When a Cold Front Passed From Station Data asks students to find the hour from a table of sample readings.

Frequently Asked Questions

Growing populations use more water, land and food, and choices such as irrigation or overfishing can drain a lake or collapse a fishery. The Aral Sea and Atlantic cod case studies trace both stories with catch and area data. Other sheets show fixes, such as cover crops and rain gardens.
