SECTION 1 Landforms Question: By which processes do weathering and erosion wear down the land?

SECTION 1 Landforms Weathering and Erosion Weathering physical processes • heating and cooling •

SECTION 1 Landforms Weathering and Erosion Weathering physical processes • heating and cooling • freezing and thawing • tree roots chemical processes • substances in air and water Erosion water • rainfall • rivers • waves wind • abrasion • from one place to another ice • glaciers

SECTION 2 The Hydrosphere Question: What roles do evaporation, condensation, and precipitation play in

SECTION 2 The Hydrosphere Question: What roles do evaporation, condensation, and precipitation play in the hydrologic cycle?

SECTION 2 The Hydrosphere Condensation: as water vapor rises it forms droplets. Precipitation: droplets

SECTION 2 The Hydrosphere Condensation: as water vapor rises it forms droplets. Precipitation: droplets may become heavy enough to fall as rain, snow, or hail. Evaporation: energy transforms water into vapor. Surface Water

SECTION 3 Natural Resources Question: What are the causes and effects of air pollution?

SECTION 3 Natural Resources Question: What are the causes and effects of air pollution?

SECTION 3 Natural Resources Causes: Factories and automobiles burn fuel, releasing smoke and fumes

SECTION 3 Natural Resources Causes: Factories and automobiles burn fuel, releasing smoke and fumes into the atmosphere. Effects: Causes acid rain, which can damage trees and kill fish in lakes; may damage the ozone layer; presents a threat to human health
