Geology Final exam Review EXAM 1 1. What is a mineral? A mineral is a naturally-occurring‚ inargonaic‚ crystalline solid with a definite chemical composition and characteristic physical properties. 2. What are eight chemical elements that make up over 99 percent of Earth’s crust? Oxygen (O)‚ Silicon (Si)‚ Aliminum (Al)‚ Iron (Fe)‚ Calcium (Ca)‚ Sodium (Ca)‚ Potassium (Na)‚ Magnesium (K) 3. What are six fundamental geologic principles which are used in relative dating? Superposition‚ original

INDUCTIVE METHOD What is the Inductive Method? The inductive teaching method or process goes from the specific to the general and may be based on specific experiments or experimental learning exercises. Advantages 1. It gives a new knowledge. 2. It is a method of discovery. 3. It is a method of teaching. 4. Child acquires firsthand knowledge and information by actual observation. 5. It is a slow process. 6. It trains the mind and gives self confidence and initiative 7. It is full

material‚ a definition that is different from the way we defined a mineral back in Chapter 2. Here the word mineral can be any substance that comes from the Earth. Finding and exploiting mineral deposits requires the application of the principles of geology that you have learned throughout this course. Some minerals are used as they are found in the ground‚ i.e. they require no further processing or very little processing. For example - gemstones‚ sand‚ gravel‚ and salt (halite). Most minerals must be

Caribbean Geology The oldest land areas of the modern Caribbean are at the extreme ends of the arc of islands in Cuba and Trinidad. The Greater Antillean islands have all had a somewhat similar geological history but they differ from one another in the distribution‚ form and erosion patterns of the limestones deposited during several phases of submergence and uplift through the Tertiary period and Pleistocene. Apart from sporadic unions between islands now separated by shallow seas‚ as within the

A grouping of 110 to 112 million-year-old dinosaur footprints pressed into mud from the Cretaceous Period have now been safely moved from their original setting on the grounds of NASA’s Goddard Space Flight Center in Greenbelt‚ Md. Until further scientific study is possible‚ the footprints‚ now wrapped in protective material‚ will be stored on the Goddard campus. The discovery of dinosaur footprints came to light in August 2012 when well-known Maryland-based dinosaur hunter Ray Stanford brought

2.1. Geology Jalpaiguri Districts almost entirely covered with alluvium expect that a narrow belt of hard rock is exposed along the northern border of the districts. The geological formations found in the districts are given below in the order of increasing antiquity. • Recent and Sub-Recent: Alluvium and other soils boulder and people beds. Miocene: - Siwaliks: - Sandstone with clay and lignite. Permian (Lower Gondwana):- Sandstone shape with Genes of Graphite coal. • Pre-cambnan (Buxa series):

Bahariya Bahariya oasis is a natural oval shaped depression. It is located at the contact between cretaceous and Eocene deposits. One of the early geologic works was carried out by Ball and Beadnell (1903). They produce a topographical- geological map of the oasis and discuss the stratigraphy of the rock exposed. They distinguished three topographic features; the bounding escarpments; the conical hills within the depression and the oasis floor. They notice that the southern scarp is steeper than

1.1- Introduction Availability of natural resources and their proper application to overall development activities is the key factor for the economic growth of any nation. Bangladesh‚ though it is a small country of about 143‚998 sq km‚ has a number of mineral resources within its territory. The mineral resources so far discovered are mineral fuels (oil‚ gas‚ coal‚ peat)‚ hard rock‚ limestone‚ white clay‚ glass sand and heavy mineral sands. It was previously assumed that the geological setting of

Today‚ the Grand Canyon is consider one of most fascinating natural wonders of the world due to its natural features and rock deposition that date back to millions of years ago. The Grand Canyon is a canyon divided
