Introduction We know very well that the location of the landmass on earth is changing since it was created. In the beginning, there was a huge single landmass on the earth. But by some natural activities, this huge landmass was split into several parts and also move away from its previous location. At present, there are seven huge land masses known as continents. However, these are also drifting from the location. To define this movement of land masses, scientists proposed a theory known as Plate Tectonics. According to the scientific hypothesis of plate tectonics, the underground activities of the ... Read More

Introduction Minerals or rocks are something that the earth is blessed with. There were many types of rocks present in our nature like sedimentary rocks, igneous rocks, and metamorphic rocks. We discussed metamorphic rocks. Metamorphic rocks are created when extreme heat and pressure change and change the original rock into a new type of rock, sedimentary or igneous rocks are transformed into new metamorphic rocks under extreme heat and pressure like magma inside the earth. The changes that occurred during this process of metamorphism. This is because of the change in the pressure and temperature that changes the configuration ... Read More

Earthquakes are natural phenomena that occur when there is sudden movement or displacement of tectonic plates beneath the earth's surface. They can be very destructive, leading to loss of lives, destruction of property, and other social and economic impacts. The intensity of an earthquake is a measure of the energy released by the earthquake and is calculated on the Richter scale. The difference between an earthquake with intensity 7.1 and an earthquake with intensity 7.2 might seem small, but it can have a significant impact on the destruction caused. Earthquake of Intensity 7.1 An earthquake with an intensity of 7.1 ... Read More

Natural disasters can be some of the most terrifying and destructive events that can occur on our planet. Among these, earthquakes and volcanoes are two of the most common natural disasters. Although both are related to the Earth's crust and can have devastating consequences, they are distinct phenomena with their own characteristics and causes. In this essay, we will explore the differences between earthquakes and volcanoes. What are Volcanoes? A volcano is a vent or opening in the Earth's crust through which molten rock, ash, and gas can escape. Volcanoes are usually located at the boundaries of tectonic plates or ... Read More

The World Geodetic System 1984 (WGS84) and the North American Datum 1983 (NAD83) are two geodetic coordinate reference systems used for position on the earth's surface. It is important to use the correct reference frame for a given application, as using the wrong one can result in significant positioning errors. WGS84 is the reference frame used by GPS devices, whereas NAD83 is used by mapping and surveying applications in North America. Read this article to find out more about WGS84 and NAD83 and how they are different from each other. What is WGS84? WGS 84 determines the Earth's orientation in ... Read More

Parasites and parasitoids are two different types of organisms that rely on other organisms for survival. Both are common in nature and have a significant impact on their hosts. However, there is a crucial difference between the two that sets them apart. In this essay, we will explore the differences between parasites and parasitoids in detail. What are Parasites? The term "parasite" comes from the Greek words para, which means "alongside, " and sitos, which means "meal"; "parasitos" means "eating at another person's table." A parasite is another organism which receives nourishment from another organism, termed the host. Parasites may ... Read More

Introduction The classification of science is not limited to the umbrella branches of Physics, Chemistry, and Biology. Instead, even under these branches, we have hundreds of subbranches based on various factors like areas of application, concepts concerned, concepts studied, etc. Classification is important since it makes advanced studies easier. For example, up till high school, you study the umbrella branches of Physics, Chemistry, and Biology. But the concepts taught at this level are simple and limited. When you go to the graduate or postgraduate level, your syllabus is advanced, and therefore, you cannot study two branches at once. Instead, ... Read More

Introduction Magma and lava are two different parts of molten rocks, one that is stored on the earth’s crust and the other one emitted through the vent of a volcano. Despite both these natural components being molten rocks and both emitting from the deep down of earth’s crust, there are a few sheer differences between them in real-time. What are Magma and Lava? Magma Magma can be defined as an extremely hot semi-liquid natural component that is stored under the earth’s crust. The layered structure of the earth consists of four different layers, the inner core, the outer core, mantle ... Read More

Introduction The process of soil erosion occurs either slowly or at an alarming rate. It is the process and by it, the upper layer of soil eras through water or air. Soil erosion has many causes and it affects many ways to the environment. The causes include the heavy rainfall and the logging process. The effects of it are Clogging of Waterways and Destruction of Infrastructure. Definition of Soil Erosion Soil erosion is a process through which the top fertile layer of the soil is lost. Soil erosion makes the soil less fertile and the production of crops becomes ... Read More

Introduction The sedimentary rocks are formed naturally by the deposition of the pieces of rocks or materials that already exist on earth get accumulated. If these sediments are buried deep within the earth, due to cementation and compaction they accumulate to form the sedimentary rocks. There are several other processes by which these sedimentary rocks are formed. These are deposition of other rock materials that are carried by the wind from sedimentary rocks, precipitation of several solutions, deposition of biogenic activities, and dissolution and erosion of materials. There are several types of sedimentary rocks like organic sedimentary rocks, chemical ... Read More
