Alfred Wegener was a german scientist who developed the theory of Continental drift. He believed all the continents were one land mass. He called this super continent “Pangea”. Wegener used evidence from three sources to support his theory. First, was fossil evidence from reptiles and plants. “Cynognathus” was a reptile that had fossils found on South Africa, and Africa. This is only possible because of continental drift, the animal couldn't have swam across a whole ocean. The next reptile is…

Do you know that there are almost two million marine species are estimated to exist in the ocean? Ocean, or marine, is the hometown of some of people. But we are still discovering and learning this familiar and unfamiliar biomes. The location, temperature, characteristic and dwellers are quite differ with other biomes on the earth. Ocean is the biggest part on the earth. There 71% of area on the earth have been covered by the ocean. The ocean entailed the 97% of liquid on the earth. “The oceans…

Jared Diamond in his book Guns, Germs, and Steel: The Fates of Human Societies has gone repeatedly explaining many reasons as to why places like Eurasia and New Guinea developed so differently. The argument of chapter ten is that the shape and major axes of continents affect the distribution of crops and domesticated animals. The continents that Diamond uses is Africa, the Americas, and Eurasia. With Africa and the Americas both have their major axis that are longitude (north to south) while…

The Commonwealth of Puerto Rico is a self-governing territory of the United States on an island of the Greater Antilles in the Caribbean. The Puerto Rican political relationship with United States has remained steady and non-violent since the take over after Spanish-American War. The island is considered a part of America, but votes on whether to remain a Commonwealth separate from 50 states or become the 51st state. Political relationship is quite extensive with United States Federal Government…

There are those who live for the sun and can spend hours out soaking up the feeling of warmth. Then there are those who prefer to stay inside and escape from the powerful UV rays that come in contact with their body. Both types of people are at fault in the way in which they are using the sun. Those who spend too much time outside may develop skin cancer. Skin cancer is the most common cancer; about 3.5 million cases of basal and squamous cell skin cancer are diagnosed each year. Another 73,000…

Skin cancer, the most common form of cancer in the United States, is defined as the uncontrolled growth of abnormal skin cells following unrepairable DNA damage to the skin. This DNA damage leads to cellular mutation and causes skin cells to multiply quickly, thus forming tumors and abnormal growths. There are several causes of skin cancer, including sunburn and ultraviolet light exposure throughout life with environmental and hereditary elements. Ultraviolet light, a type of electromagnetic…

of the Quaternary Period. Without the dinosaurs, plant life had an opportunity to flourish during the Cenozoic Era. Nearly every plant living today had its roots in the Cenozoic Era. The climate was cold, and warm in some areas,and hotter near the equator like now. The Cenozoic Era is divided into two periods, the Paleogene and Neogene which are divided into epochs. The Cenozoic has seen the extinction of the non-avian dinosaurs and the rise of mankind. It is marked by the Cretaceous-Tertiary…

Over the course of the Earth’s history there have been five Mass Extinctions, a global event where at least 75% of the life on Earth dies. In most of these events the only life form to survive are bacteria, or other small organisms that can hide from the destructive force that wipes out everything else. The Cretaceous-Tertiary (K/T) is the most recent and most famous Mass Extinction, taking place 65 million years ago. The K/T is the event in which the dinosaurs died in. The cause of this event…

Multiple Sclerosis is an autoimmune disease and claims the lives of an estimated 2.5 million people in the world. In Australia, it has been researched that the further away a person is from the equator, the more likely is the person is to develop multiple sclerosis. For instance, in the far north of Queensland the disease occurs 12 in every 100000 people, while in New South Wales, it rises to 36 people out of 100000, and even higher in Tasmania with 76 people out of 100000. Although multiple…

There are many types of renewable energy sources in the world. We can run the world forever off of these energy sources, until something catastrophic happens to the planet. There can be a plethora of similarities and differences between the types of energy. So I am going to break down solar energy and wind energy. The most obvious and simple similarity of these two is that they create power, and lots of it. A single solar panel can create a few kilowatts (kW) to over 100. While a single wind…
