Rocks and minerals are all around us! They help us to develop new technologies and are used in our everyday lives. Our use of rocks and minerals includes as building material, cosmetics, cars, roads, and appliances. In order maintain a healthy lifestyle and strengthen the body, humans need to consume minerals daily.

Rocks and minerals play a valuable role in natural systems such as providing habitat like the cliffs at Grand Canyon National Park where endangered condors nest, or provide soil nutrients in Redwood where the tallest trees in the world grow. Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3-D objects, or knowing rates of crystallization.

Natural objects, such as rocks and minerals, contribute to the beauty and wonderment of the National Parks and should be left, as they were found, so that others can experience a sense of discovery. This video provides an introduction to some basic properties of rocks and minerals. Learn what rocks are made of, where they come from, and how they are classified. Learn about the physical properties of a mineral and some of the most common minerals in the Earth's crust.

The Earth Materials Module consists of four sequential investigations dealing with observable characteristics of solid materials from the earth — rocks and minerals. The focus is on taking materials apart to find what they are made of and putting materials together to better understand their properties. The module introduces fundamental concepts in earth science and takes advantage of the students' intrinsic interest in the subject matter and in the physical world around them. Module Summary — Earth Materials 2nd Ed. Acrobat Reader is available free from Adobe.

A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition and the way in which it is formed. Rocks are usually grouped into three main groups: igneous rocks , sedimentary rocks and metamorphic rocks. Rocks form the Earth's outer solid layer, the crust , and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed.

Rocks and Minerals

Rock , in geology , naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. Rocks are commonly divided into three major classes according to the processes that resulted in their formation. These classes are 1 igneous rocks, which have solidified from molten material called magma; 2 sedimentary rocks, those consisting of fragments derived from preexisting rocks or of materials precipitated from solutions; and 3 metamorphic rocks, which have been derived from either igneous or sedimentary rocks under conditions that caused changes in mineralogical composition , texture, and internal structure. These three classes, in turn, are subdivided into numerous groups and types on the basis of various factors, the most important of which are chemical, mineralogical, and textural attributes.

There are three types of rocks: igneous, sedimentary and metamorphic. Each of these types is part of the rock cycle. Through changes in conditions one rock type can become another rock type.

Our Earth is made mostly of rocks. The rocks are composed of mineral grains combined in different ways and having various properties. Minerals are naturally occurring chemical compounds in which atoms are arranged in three-dimensional patterns. The kind of elements and their arrangements lead to a particular appearance and certain properties for each mineral. The same chemical elements when arranged in different patterns show different characteristics. Classic examples are minerals made of the element carbon C. Flat planes of carbon atoms form the mineral graphite, which is a gray, slippery, soft material.

 - Беккер улыбнулся и достал из кармана пиджака ручку.  - Я хотел бы составить официальную жалобу городским властям. Вы мне поможете. Человек вашей репутации - ценнейший свидетель. Клушару эта идея понравилась.

Лифт спускался на пятьдесят ярдов вниз и затем двигался вбок по укрепленному туннелю еще сто девять ярдов в подземное помещение основного комплекса агентства. Лифт, соединяющий шифровалку с основным зданием, получал питание из главного комплекса, и оно действовало, несмотря на отключение питания шифровалки. Стратмору, разумеется, это было хорошо известно, но даже когда Сьюзан порывалась уйти через главный выход, он не обмолвился об этом ни единым словом. Он не мог пока ее отпустить - время еще не пришло. И размышлял о том, что должен ей сказать, чтобы убедить остаться.

Он поднялся по служебной лестнице до высшего поста в агентстве потому, что работал не покладая рук, но также и благодаря редкой целеустремленности и заслуженному уважению со стороны своих предшественников. Он был первым афроамериканцем на посту директора Агентства национальной безопасности, но эту его отличительную черту никто никогда даже не упоминал, потому что политическая партия, которую он поддерживал, решительно не принимала этого во внимание, и его коллеги следовали этому примеру. Фонтейн заставил Мидж и Бринкерхоффа стоять, пока сам он молча совершал свой обычный ритуал заваривания кофе сорта Гватемальская ява.

 Ну и проблема! - засмеялся Хейл.  - Думаю, коммандер мне его откроет. Разве не так, коммандер. - Ни в коем случае! - отрезал Стратмор.

Беккер заговорил по-испански с сильным франко-американским акцентом: - Меня зовут Дэвид Беккер. Я из канадского посольства. Наш гражданин был сегодня доставлен в вашу больницу. Я хотел бы получить информацию о нем, с тем чтобы посольство могло оплатить его лечение.

Чутье подсказывает мне, что здесь все верно. Бринкерхофф нахмурился. Даже директор не ставил под сомнение чутье Мидж Милкен - у нее была странная особенность всегда оказываться правой.

Сеньор?.
