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.
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 Earths geological history because its layers often hold fossils and other geological clues.
Crystals are made up of minerals hardened into distinct shapes with regular repeating patterns. This informative book takes a look at the underground process that creates crystals, from sparkling quartz to ordinary salt, as well as where they are found and how they are mined.
Rock collecting is a hobby that is easy to start. This engaging book describes how to dig, where you can and can't dig (restricted in national parks), the necessary equipment, how to identify rocks and gems, and the proper recording and storage of your collection.
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.
Heat, pressure and stress can also change some igneous or sedimentary rocks into other kinds of rocks. This fact-filled book describes the process that turns limestone into marble, shale into slate, and granite into gneiss. Metamorphic rocks are often used as materials for floors, roofs, and counter tops because of their beauty.
Igneous rock has a dramatic beginningit requires red-hot volcanic activity. This fact-filled book explains how granite, lava, basalt, silica, quartz and feldspar are formed after hot, molten rock cools. Readers will also learn about volcanoes and tectonic plates, the minerals that make up igneous rocks, and the crystallization of rock material.
Life in an Industrial Citylooks at everyday life in cities that have grown up around a particular industry. Most people in these cities work in factories, warehouses, ports, airports, or transportation. Houston, Texas, is used as an example showing how people live, work, and relax in the industrial part of the city.
Life in a Suburban City looks at living in cities that have spread from the center far into the countryside. Many people live and work in areas that are miles from downtown. Los Angeles, California is the featured example, and focuses on family life in a typical suburb.
Trees were one of the first natural resources used by man. In North American, most native and early European settlements were set up near forests from where wood was harvested for firewood, building homes and boats, and for fortifying villages. Western Canada had, and continues to have, huge coniferous forests. McKenzie in British Columbia, Canada, is a community based on timber mills, timber supply and tourism. It has a population of 5,450 people.
Few people live in the business district of big modern cities. The area where people live in a big city is usually filled with office buildings, banks, insurance companies, and stores. This book focuses on New York City, and looks at the everyday life of workers in the business district.
Life in a Residential City looks at living in the housing zone of a big modern city. City life, with lots of people, traffic, buildings, and roads, is busy and fast-paced. Toronto, Ontario, is the featured example. It looks at houses and apartments, and how people commute to work.
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.
People first domesticated wild animals and plants more than 10,000 years ago. The first peoples of North America quickly learned to farm using hand- and animal-power. As technology developed, farming machines were invented. These helped develop farming in many regions of North America previously too difficult to cultivate. From 1840 to 1880, Wisconsin USA became the breadbasket of America, and crop- and livestock-farming developed quickly. The village of Monticello is famous for its dairy farming and cheese. The community is still largely based on this. It has a population of about 1,200 people and is the focus of this book about life in a farming community.
