Children's Literature - RevaBeth Russell
The "Science of Catastrophe" series uses science to explain what happens in different disasters and excels in being accurate and readable and the price is affordable. The series has beautiful illustrations and detailed diagrams of the science involved. For example, diagrams and the accompanying text explain how rain or hail falls into the dry air creating powerful downdrafts. Winds hit the surface and blow outward causing the winds to swirl up and around as vortexes, making a microburst. The diagram for the science of lightning shows the lower warmer part of the cloud with negative static charges on the water droplets. The colder upper part of the cloud has positive static charges. The negative charges move down toward the positive charges in the ground. As the opposite charges meet, electricity flows as lightning. The science of thunderstorms, cyclones, heatwaves, and more are explained. A hurricane starts in a similar way as a thunderstorm, with warm moist air colliding with cool air—except it starts over a warm ocean. Then water vapor and heat from the sea feeds the bands of cumulus clouds. The moist warm air rises and the cool air falls causing swirling bands of wind and rain to develop. An average-sized hurricane is about 300 miles or 480 kilometers across. Katrina, in 2005, was ranked a category six for strength and a category three for number of people who died. Many state earth science cores require understanding of the Coriolis Effect. It is the Coriolis Effect, or earth's rotation and shape that determine the rotation of a cyclone.
