Fossils provide a valuable look into our ancient past. By examining fossils and the rocks they are found in, scientists understand the effects that events such as mass extinctions, meteroite impacts, and climate change have on Earth's history. This fascinating book explains how plants and animals become fossils, how they are extracted from excavation sites, and how paleontologists and geologists piece together Earth's history by studying these ancient clues.

Mining People mine for coal, oil, minerals, and metals. These are used for energy and as raw products to make things. In various parts of North America there are huge areas rich in one or more of these natural resources. Gillette, in Wyoming, is the coal-mining capital of the USA. Nearby is the small community of Moorcroft. The community developed from an old wild west cattle-ranching center and is now largely based on oil and coal-mining. About 900 people live in the small town.

Who are we, really? We share traits with our parents, but our genetic makeup is unique. Each one of us is a one-and-only creation. Through colourful photos, diagrams, and text, you can learn about genetics. See how the simple pea plant taught us the rules of inheritance. Find out how our genetic code is unlocking the mystery of where we came from and our connections with all living things.

From ancient Pueblo homes to the Australian mining town where half the population lives underground, this appealing book uses cutaway illustrations to introduce readers to homes that were built below ground. Labeled diagrams of underground homes and fun facts will make this enjoyable read highly useful.

It all starts with erosion for sedimentary rock. Worn down bits of rock become pressed together under pressure into strata, or layers. The formation of rock such as sandstone, shale, limestone, and dolomite is explained in this fact-filled book. Readers will also learn that this type of rock is useful in determining the Earth's geological history because its layers often hold fossils and other geological clues.

What is the Rock Cycle describes the natural transformation of one type of rock into others. Beginning with igneous rocks made in volcanic eruptions, rock is weathered and eroded gradually to form a sediment. This sediment is then deposited and pressed into layers making sedimentary rocks. These in turn are transformed by heat and pressure into metamorphic rocks. Heat makes these melt into magma which, together with molten rock from the core of the Earth, make new igneous rocks.

Why do people migrate to and settle in the places they do? Fascinating examples in history help explain how the earliest human settlements were situated close to fertile ground and rivers for farming and raising livestock. Other determining factors have included areas that offered defensive advantages, resources such as metals, salt, and fossil fuels, and locations on trading routes. In modern times proximity to commercial centers and transportation links, such as railways, canals, and airports, have become more important. Examples featured include settling the Nile in ancient Egypt; the shaping of Central America by trade and colonization; the Industrial Revolution in Britain; the opening up of the American West; the Gold Rush; and the colonization of Australia. The concepts of urbanization - the settlement and growth of cities - and suburbanization, the return to the countryside and the growth of commuter towns, are both examined.

Flooding from torrential rain and melting snows can devastate areas where people live. This informative book examines what scientists know about flooding, whether we can predict floods, and how we learn from each event. By studying the destruction they cause, scientists and engineers continue to come up with new and improved technologies to predict severe weather and better protect cities, buildings, and people. Case studies and brief bios of key scientists and organizations highlight the information.

Climate change is one of the most serious threats to the world's oceans causing ecosystem damage, coastal erosion, and ocean acidification.

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.

Earth's surface is constantly being changed by heat, water, ice, salt, plants, and animals. Sometimes the changes are destructive to human activities such as farming and the building of structures. This interesting title shows the different ways people try to stop or reduce this change in the land. Examples feature such structures as dikes to hold back water and windbreaks, and adding shrubs, grass, and trees to an area of land to prevent erosion. Teacher's guide available.
