The Earth’s crust is an important layer which is extremely thin which is made up of rocks which form the outermost outer layer of our planet. It is equivalent to less than half of 1 percent of the total mass of the planet, but it plays a vital role in most of the natural cycles that occur throughout … Read more
During the Mesozoic era also known as the era of ” Middle Life “, life managed to diversify rapidly and giant reptiles, dinosaurs and other monstrous beasts roamed the Earth. This period, which lasted from about 252 million years ago to about 66 million years ago, was also known as the age of reptiles or the age of dinosaurs . During the period, there were … Read more
The Cenozoic era was the third of the major epochs in earth’s history, beginning approximately 66 million years ago and extending to the present. It was the time interval during which the continents assumed their modern configuration and the different geographical positions that they maintain to this day and during which the flora and fauna of the earth evolved to reach the current ones. The term Cenozoic, originally spelled Kainozoic, was introduced … Read more
The Paleozoic era , which happened and spanned from approximately 542 million years ago to 251 million years ago, was a time when a host of major changes occurred on Earth . The era began with the breakup of a supercontinent known as Pannotia and the formation of a new one. The plants spread and evolved and the first vertebrate animals that existed colonized the land. What is the Paleozoic era? The … Read more
The abyssal zone is the part of the ocean which is located more than 2,000 meters of depth in the sea. The area is defined mainly by its different environmental conditions, which are very uniform, a characteristic that is reflected in the different forms of life that inhabit it. Nether kingdom is the greatest environment for life on Earth, covering approximately 300,000,000 square kilometers, about the 60 per cent of the total … Read more
The hadal zone is the deepest region of the ocean, extending from approximately 6,000 meters to 11,000 meters below the sea surface . This zone does not extend along the ocean floor, but exists only in the deepest ocean trenches . Because the light does not reach this part of the ocean, it is impossible for plants to be able to grow, but there are still hardy creatures … Read more
The photic zone is the surface layer of the oceans or bodies of water. This area has enough light for organisms to carry out the photosynthesis process . In the ocean, about 90% of life can be found and developed within this area. The depth of this zone can vary enormously, depending on a number of different factors. It is also called the euphotic zone , and in it we … Read more
The rocks, minerals and soils that we find on earth can generally change their structure through the action or influence of certain environmental forces . The biological activity , the climate end and erosion agents such as water, wind and ice are examples of environmental forces influencing the decomposition continuous in wear and in the detachment of rocks and soils. This set of situations is what is called weathering. So we can say that weathering is the process in which … Read more
The sedimentation in science geological earth, is the process of deposition of the material solid from a state of suspension or solution in a fluid that is usually air or water, and then is transported to the basin sediments . It also includes the different glacial ice deposits and those materials that are collected by means of gravity alone, such as astragalus deposits, or accumulations of rock debris at the base of cliffs. The term … Read more
The desertification can be defined as a process of degradation of the land that is mainly in the arid , semiarid and subhumid due to various factors, including climate variations and human activities . To put it another way, desertification results in the persistent degradation of drylands that occupy practically half of our planet’s land surface and ecosystems.that are more fragile due to man-made activities and different changes in the weather. Desertification … Read more
