Earth in the Solar System at Project Learning Tree. The Road Ahead. Mytinygarden [ver:v] 2010. Untitled. Rock Key. The Rock Identification Key - by Don PeckRock Key Table of Contents What Are Rocks? Rocks are what the crust of the earth is made of. They are the mountains and the bottom of the ocean. They are everywhere on earth, but often buried under soil. Rocks are made of minerals, like quartz, calcite, feldspars, and micas. Most rocks are made from more than one mineral, but there are quite a few kinds that are made from only one mineral. Minerals are not rocks, rocks are made of minerals. A car is made of steel, glass, and plastic. . [ Return to Rock Key Table of Contents ] What Minerals Form Rocks? ROCKS AND THEIR USES. Click here for a printable version Title: Rocks and Their UsesLevel: K-12Day/Time: Academic ExpectationsCore Content for Assessment: Objective: Introduce students to different types of rocks and their uses.

Background Information: Rocks normally consist of several minerals, some essential, some accessory. A rock may be thought of as a "mineral environment. " COAL: A sedimentary rock, formed from decayed plants, is mainly used in power plants to make electricity. LIMESTONE: A sedimentary rock, it is used mainly in the manufacture of Portland cement, the production of lime, manufacture of paper, petrochemicals, insecticides, linoleum, fiberglass, glass, carpet backing and as the coating on many types of chewing gum.

SHALE: A sedimentary rock, well stratified in thin beds. CONGLOMERATE: A sedimentary rock with a variable hardness, consisted of rounded or angular rock or mineral fragments cemented by silica, lime, iron oxide, etc. SANDSTONE: A sedimentary rock more or less rounded. Discussion: Guide To Stones Used for Houses of Worship in Northeastern Ohio - Type Of Stones. A wide variety of stone types have been used in the construction of houses of worship in Northeastern Ohio. Some of this stone is from this region, but other types are from various places around the world. Stone used in Northeastern Ohio's sacred structures includes examples of all three of the major rock types: igneous rocks, such as granite; sedimentary rocks, such as limestone and sandstone; and metamorphic rocks, such as marble and slate.

These stones have been used in many different ways, ranging from exterior facing and columns to interior flooring and statuary. Throughout the centuries and all over the world, exteriors of many types of sacred buildings have been made of stone. Due to the high cost of transporting stone, it usually came from nearby quarries, or from quarries located near bodies of water. In medieval times in Europe, transportation over long distances by land was extremely expensive. Transportation by water was preferred. Deep Lock Quarry, Peninsula. Ohio Fossil Sites and Collecting Localities. America's Volcanic Past - Ohio. Volcanic Highlights and Features: Ohio Ohio Regions Ohio - Brief Geologic History Ohio's Volcanic Rocks Cleveland - Volcanic Building Stones Gold in Ohio Volcanic Ash Deposits Ohio's Bentonite:3 The island arcs associated with continental collision were the sites of active volcanoes, as documented by the widespread beds of volcanic ash preserved in Ohio's Ordovician rocks.

The ash layers, which to geologists are wonderful time lines because they were deposited instantaneously over a wide geographic area, have been altered to a special type of clay known as a bentonite. There are a number of bentonite beds in Ohio's Ordovician rocks, but two beds in Middle Ordovician rocks, the Deicke bentonite and the Millbrig bentonite, may represent some of the largest explosive volcanic eruptions in the geologic record.

These beds have been traced from the Mississippi River eastward across North America and Europe and into Russia. Urban Rocks. Level: Second grade to senior high Anticipated Learning Outcomes Students will develop an appreciation of the importance of rock material to our civilization. Students will observe and develop an appreciation for materials used for buildings and monuments. Students will develop observational skills. Students will apply information on various aspects of geology, for instance the formation of various rock types, from classroom lectures and laboratories. Introduction Our civilization is heavily dependent on geologic materials for constructing roads, bridges, buildings, and monuments.

Stone used for building can be found in virtually any city or town, sometimes in a great many varieties. The concept of the urban field trip is now well established. Materials and Human Resources Needed Worksheets, designed for particular sites (see sample). Background and Site Selection In order to develop a successful unit utilizing building stone one should have a background in geology. Geological Focal Points. Ecology Lesson Plans.
