◦ Weather: Concepts include Earth being surrounded by layers of gases (atmosphere), that weather happens in the atmosphere, how water in the atmosphere forms clouds, and how water falls back as precipitation. It also notes that scientists record weather patterns for predictions.
◦ Climate: This subbranch differentiates climate as an area's typical weather over years, from weather as atmospheric conditions at a given place and time. It also explains how atmospheric gases trap solar energy to keep Earth warm, and how climate affects ocean life.
◦ Hurricanes: This section describes hurricanes as powerful natural hazards with strong winds, often accompanied by floods. It highlights that humans cannot eliminate them but can reduce their impact, and that meteorologists warn people while engineers study damage to create stronger buildings.
◦ Tornadoes: Similar to hurricanes, tornadoes are presented as natural hazards resulting from natural processes, characterized by powerful, swirling winds. The text states that while tornadoes cannot be eliminated, steps can be taken to reduce their impact. It also mentions that scientists study tornadoes for better forecasting, and people learn safety procedures and use watches, warnings, and drills.
◦ Floods: Floods are defined as natural hazards from natural processes that can harm people and property. The sources also mention that floods occurred in ancient times, cannot be eliminated, but can have benefits and their impact can be reduced through measures like dam control.
