A joint is defined as a fracture in a rock between the sides of which there is no observable relative movement. They are present is most consolidated rocks of igneous‚ metamorphic and sedimentary origin. Joints may form as a result of either diastrophism or contraction. Description: (i) A series of parallel joints is called a ’joint set’. (ii) Two or more joint sets intersecting each other produce a ’joint system’. (iii) Two sets of joints nearly at right angles to one another‚ produced by the

Rocks are classified in order to communicate information about them. All classifications of limestones are arbitrary and they frequently overlap or do not fit ones particular needs. Since binocular microscopes or hand lenses are the tools that are commonly available to the explorationist‚ a practical classification should be based on descriptions using them. When these instruments are used‚ it is usually possible to identify the individual grains forming the rock. Thus most classifications require

Rocks and minerals are all around us. Earth’s crust and part of its mantle are made of rock. Rocks are made of minerals and have different properties. The properties of rocks include color‚ texture‚ luster‚ and hardness. We use rocks and minerals in many different ways. The steel in our buildings is made with iron‚ which is a mineral. The clay and glass used in our pottery and dishes are made of a mixture of rocks and minerals. We even need minerals to stay healthy‚ and we get them from a variety

intrusive rocks harden slowly beneath the surface of the earth‚ and often form large mineral crystals within the rock. Granite is a good example of an intrusive rock.Porphyritic intrusive rocks have large crystals embedded in a matrix of smaller crystals. Pegmatite is the only porphyritic rock on the Science Olympiad list.Extrusive rocks harden quickly during a volcanic eruption and are usually smooth-grained. Basalt is the most common form of extrusive rock. |IgneousName |Classification|Description

in the rearrangement of molecules‚ but doesn’t affect their internal structures. When you make rock candy‚ you are creating a physical change. When sugar and water mix together‚ they are not forming a new substance‚ sugar dissolves‚ but it doesn’t disappear. So when you crystallize it‚ it still has the same chemical structure‚ the only thing that changed is the physical appearance. When we create the rock candy it will take about a week or more for it to fully form. While we do this project we hope

Madonna on the Rocks Madonna on the Rocks by Leonardo da Vinci or also known as Virgin on the Rocks caused quite a commotion between Da Vinci and the commissioners due to his unorthodox methods. Madonna on Rocks was one of the only paintings left unfinished by Da Vinci.

Sex‚ Drugs‚ Violence and Rebellion. Those were my low expectations of the heavy metal rock concert that took place on 924 Gilman Street in Berkeley‚ California. Due to my lack of knowledge with attending Rock Concerts‚ (mind you this was my first-ever concert in general)‚ my expectations of the concert were based off of stereotypes and television shows that I scrutinized and judged when I was in elementary school. However‚ my thoughts about the concert‚ the people that I was going to encounter‚ and

Rock candy is a candy made with sugar that I chose to attempt to grow on a wooden skewer. This delicious candy is actually crystallized sugar that I grew from a sugar-water solution. In this science fair project I have learn how to grow my own rock candy and determine if you use different types of sugar‚ it will change the growth rate of your sugar crystals. When I added
