Minerals are chemicals that are the building blocks of rocks. Metals, crystals, and gemstones are all minerals found in rocks. This interesting book describes how to identify minerals, where they can be found, the rock cycle process, the uses of minerals, and how they are mined.
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.
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 colorful 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.
All life starts with a set of instructions that can turn basic cells into hearts, tails, flower petals, or toenails. DNA is the amazing code of life that is found in every organism. Through colorful photos, diagrams, and text, you can learn how DNA is passed from cell to cell, controlling growth and change in all living things. Find out how we can use the properties of DNA to save endangered animals and even to catch criminals!
From insects to elephants, every living thing on this planet is made up of cells, the tiny building blocks of plant and animal life. Each cell is alive-and each has work to do! What do cells look like? How do millions and billions of cells work together to form one plant, one animal, or one human being? Guided by colorful photos, diagrams, and text, you can take a closer look at the amazing world of cell science-and see what's next.
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.
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.
