Earthquakes Eruptions And Other Events That Change Earth

This exciting book explains how the shape of Earth can change with the sudden movement of Earth's crust or when molten rock explodes out of an opening in Earth's surface. Young readers will be fascinated to discover how volcanoes form - destroying the landscape and creating new landforms at the same time. They will also learn about tectonic plates and fault lines, the damage earthquakes can cause, and how to stay safe when an earthquake happens. Teacher's guide available.

Early readers examine how volcanoes, earthquakes, and erosion change the surface of the Earth.

Volcanic eruptions are common, with more than 50 volcanic eruptions in the United States alone in the past 31 years. These eruptions can have devastating economic and social consequences, even at great distances from the volcano. Fortunately many eruptions are preceded by unrest that can be detected using ground, airborne, and spaceborne instruments. Data from these instruments, combined with basic understanding of how volcanoes work, form the basis for forecasting eruptionsâ€"where, when, how big, how long, and the consequences. Accurate forecasts of the likelihood and magnitude of an eruption in a specified timeframe are rooted in a scientific understanding of the processes that govern the storage, ascent, and eruption of magma. Yet our understanding of volcanic systems is incomplete and biased by the limited number of volcanoes and eruption styles observed with advanced instrumentation. Volcanic Eruptions and Their Repose, Unrest, Precursors, and Timing identifies key science questions, research and observation priorities, and approaches for building a volcano science community capable of tackling them. This report presents goals for making major advances in volcano science.

In a series of fun and involving hands-on earth science experiments, kids learn why the Earth bulges at the equator, demonstrate the movement of the Earth’s axis, determine how the composition of the Earth affects its motion, and replicate the cause of the day-and-night cycle. They will also determine why the sky is not dark as soon as the Sun sinks below the horizon, learn how salt beds are formed, demonstrate how air takes up space, observe the effects of cool and warm temperatures on air movement, and replicate the formation of sea breezes. Featuring color illustrations and safe, simple step-by-step instructions, Janice VanCleave again shows just how much fun science can be.

In a series of fun and involving hands-on earth science experiments, kids learn how crystals and metamorphic and sedimentary rocks form, why seismic waves move more slowly through sand, the effect of rain on hills with and without ground cover, the effect of acid on statues, and how freezing water causes rock movement. They will also determine and demonstrate how rain affects topsoil, what amount of pressure is required to fold the Earth�s crust, how a gentle breeze can move heavy objects, and how air pressure can be used to create a spraying fountain. Featuring color illustrations and safe, simple step-by-step instructions, Janice VanCleave again shows just how much fun science can be.

In this series of fun and involving hands-on earth science experiments, students will learn how atoms and molecules arrange themselves in minerals, how global warming could raise sea levels, and even how rocks melt. They will also create their own instrument to measure humidity, grow crystals, and demonstrate how soil texture affects the amount of air in soil. From lake bottoms to icebergs to hurricanes, readers will engage with this fun installment of twenty-four Janice VanCleave experiments that features color illustrations and safe, simple step-by-step instructions.

Hands-on experiments are a great way to engage young scientists. Instead of simply reading facts, they will experience the science that is happening in front of their eyes! The simple experiments in this book, illustrated in color, will unlock the secrets of planet Earth, including why Earth has layers, how continents move, and how we know Earth is round. By the time young readers are finished with the activities in this book, they will be ready to design some of their own to enter in their next science fair.
