The world and its features we see surrounding us today have not been the same throughout all of time . A lot of people believe that the way the Earth looks today is the way it has looked since the beginning. This belief is far from true. The Earth has a history that has evolved over time just like everything else. We can view the history by examining the Earth’s crust in areas. The region of the Earth that is presently known as Canada has the world’s oldest history which makes it unique. Throughout

Cambrian period 543-490 million years Introduction The Cambrian Period marks the beginning of the Paleozoic Era. This period gets its name from a place in Wales where the first examples of this type of ancient life was found. The period lasted for nearly 53 million years, from about 543 million years ago until 490 million years ago. The Cambrian Period marks an important point in the history of life on earth; it is the time when most of the major groups

The greenhouse effect is a natural process that works to maintain the warmth radiating onto the Earth’s surface. It was first discovered by Joseph Fourier in 1842, and was later expanded on by John Tyndall in 1858 and Svante Arrhenius in 1896 (Princeton.edu, 2014). When the sun’s energy reaches our atmosphere, greenhouse gasses absorb some of it and some is reflected back into space. Greenhouse gasses include nitrous oxide, carbon dioxide, water vapour, ozone and some artificial chemical such as

Montreal is located where the Canadian Shield, a Precambrian rock formation, meets a lush plain. This means Montreal has the geographic ability for economic growth with mining, as the Canadian Shield is filled with multiple types of minerals including nickel, gold, silver, and copper. While already with the

When one thinks of Death Valley National Park in California, the first image that comes to mind is usually an endless desert of dry, cracked terrain or rippling sand with little wildlife or vegetation. While that is what you’ll find in most of Death Valley today, it wasn’t always so. During the Holocene Eon and the Pleistocene ice ages, Death Valley had its fair share of streams and rivers, many of which originated from the nearby mountains. In fact, the driest area of Death Valley today was once

Sequoia – Kings Canyon National Park is a national park located in California, United States. This park has a rich history to it with beautiful scenic view all around. In 1943 two side by side national parks titled Sequoia National Park and Kings Canyon National Park came on board together and began to be jointly administered. Since then this national park is known as Sequoia – Kings Canyon National Park. The two neighboring parks are almost 66 miles long and 36 miles wide. Also, the park has an

Maker 23 located on a small island on Namaken Lake in Voyageurs National Park. Voyageurs National Park is located in Orr Minnesota just south of the Canadian border. It is also located on the Eastern edge of the Canadian Shield. An exposed area of Precambrian stone. My island does not have a specific name, but it appears to be a break off of Sweetnose island in the Blind Indian Narrows located at 48°26 '33.7"N 92°46 '33.0"W. Day Maker 23 is unique in that its location causes a division in current going

Introduction According to scientists, one of the most extraordinary bursts of evolution ever known was the Cambrian Explosion. For most of the nearly 4 billion years that life has existed on Earth, evolution produced little beyond bacteria, plankton, and multi-celled algae. Then, about between 570 and 530 million years ago, another burst of diversification occurred. This stunning period is termed the "Cambrian explosion," taking the name of the geological age in which the earlier part occurred. A

miles. The notable landmasses found within Quebec include the Canadian Shield and the Appalachian Mountains. The Encyclopedia of Britannica reveals that the Canadian Shield has ice-smoothed hills, and is the most massive area containing exposed Precambrian rock (Behiels). The Appalachian Mountains are the separating feature distinguishing the Quebec’s borders from Main, Vermont, and New Hampshire (“Quebec Mountains”). The St. Lawrence River flows southwest of Lake Ontario to the northeast. Attractions

The Life of a Brittle Starfish The type of marine organism, which will be reported on within the following text, is the Brittle Stars. The Brittle Star is also called the serpent star and a common name for a large group of echinoderms closely related to the starfish. These organisms make up the class Ophiuroidea; another common name for ophiuroidea is snake stars. These organisms can be found in all oceans but are more abundant in the Tropics. Brittle stars can come in different colors. 2
