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

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

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

Your Name: Professor’s Name: Course Number: Date of Submission: Deep Ocean Mining Part 2 Deep ocean mining is an alternative to land mining in search of minerals such as copper‚ gold‚ manganese or cobalt among other minerals. The minerals on land are being depleted owing to the increasing demand for these minerals‚ and this makes the deep sea bed an alternative to the exploitation of minerals. The fact that the water

Assignment on “Brief History of Earth” Course: ENV 107 1 Brief History of Earth The history of the Earth concerns the development of the planet Earth from its formation to the present day. Nearly all branches of natural science have contributed to the understanding of the main events of the Earth ’s past. The age of Earth is approximately one-third of the age of the universe. An immense amount of biological and geological change has occurred in that time span. Earth formed around

Alfred Wegener(1880-1930) was the first man to propose the theory gplate tectonics.h He had got a Ph.D in astronomy from the University of Berlin‚ but he was also interested in the other science field such as geophysics‚ meteorology‚ and climatology. He also contributed to meteorology by establishing to track air circulation using balloon. In 1911‚ he read a paper that listed identical fossils of plants and animals found on opposite side of the Atlantic‚ and he looked for more of such organisms
