Igneous Textures Cooling rates influence igneous rock textures. Rapid cooling at the earth’s surface results in tiny mineral crystals that can only be seen under a microscope. The resulting extrusive igneous rocks have an aphanitic texture. Rocks that form as magma cools slowly underground (intrusive igneous rocks) develop phaneritic textures‚ in which individual mineral crystals can be seen without a microscope. Some igneous rocks exhibit visible crystals (phenocrysts) in a matrix of tiny

2-15-11 Purpose: The purpose of this experiment was to take spinach leaves and extract the chlorophyll and carotenoid pigments by using acetone as the solvent. The chlorophyll and carotenoid pigments were extracted by using column chromography and alumina was used as the solvent. Solvents of different polarities were used‚ starting with the least polar‚ to extract the certain components from the leaves. They were then analyzed by using thin- layer chromatography. Procedure: The first part

eruptions of silica-poor magma. Explosive eruptions of silica-poor magma. These rocks were formed from semi-mobile to mobile and highly gaseous silica-poor magma. It rose to the surface‚ where sudden pressure relief caused explosive volcanic eruptions‚ producing fragmentary pyroclastic material or ash. Basaltic Lava. Igneous Bedrock formed approximately 342 to 400 million years ago in the Carboniferous and Devonian Periods. Local environment previously dominated by eruptions of silica-poor magma

Oxygen in Liquids (DISSOLVED OXYGEN) Dissolved Oxygen – the amount of dissolved oxygen in a body of water as an indication of the degree of the health of water and its ability to support a balanced aquatic ecosystem. Oxygen – is a clear‚ colorless‚ odorless‚ and tasteless gas that dissolves in water. Small but important amounts of it are dissolved in water. OXYGEN: Aquatic Life Depends on it Plants and Animals depend on dissolved oxygen for survival. Lack of dissolved oxygen can cause aquatic

Gold Nanoparticles for Diagnosis and Treatment of Cancer Abstract—Nanotechnology has been an extremely hot topic over the decade. It is the science‚ engineering and technology conducted at nanoscale. Two of the main applications of nanotechnology include material science and biomedicine. We have achieved great strides in applying nanotechnology to material science that is well justified by the decreasing size of electronics available in market. However we haven’t made a mark in biomedicine yet
