The SARS-CoV-2 virus, previously known by the provisional name nCoV-2019 and the particular coronavirus responsible for COVID-19, has the potential to survive outside of a host and in the environment for several days, thereby making it virulent and a potentially disease-causing contaminant. Remember that the primary mode of transmission of the virus is through tiny […]

The Characteristics of Coronaviruses
Coronaviruses are a large family of viruses that cause diseases in mammalian, avian, and reptilian species. Note that some species such as bats serve as mere reservoirs of these viruses without causing symptoms associated with an infection. In humans, some of these viruses can cause respiratory tract infections with varying severity ranging from mild illnesses […]
Structure of the Earth: Compositional vs. Mechanical Layers
The structure of the Earth consists of various spherical shells or layers that can be categorized in two manners: either by their chemical compositions or mechanical properties. Hence, compositional layers and mechanical layers are the two types of layers Categorizing the Structure of the Earth: The Difference Between Compositional Layers and Mechanical Layers The Compositional […]
The Pacific Ring of Fire Explained
The Pacific Ring of Fire or the Circum-Pacific Belt is a geologically defined path along the Pacific Ocean characterized by a string of active volcanoes and frequent earthquakes. It has a length of approximately 40,000 kilometers or 24,900 miles spanning from the western sides of the South America and North America and all the way […]
Why Volcanoes Erupt? What Causes Volcanic Eruption?
A volcanic eruption is a geological phenomenon occurring when hot materials from the interior of a planetary-mass object are thrown out of a vent or fissure found on the surface. These vents or fissures are collectively called volcanoes. The volcanoes on Earth occur because the crust is broken up into 7 major and 152 tectonic […]
Why Is Venus Hotter Than Mercury?
Mercury is the nearest planet to the Sun. It orbits at an average distance of 58 million kilometers. However, despite this proximity, Venus remains the hottest planet in the Solar System. It is about twice as far from the Sun of average as Mercury. Specifically, it orbits at an average distance of 108 million kilometers. […]
Purpose of Bird Vocalization
Research in ornithology has explored and explained the different functions of bird vocalization. Ornithologists specifically determine these functions by analyzing the acoustic structures of bird calls and bird songs, how specific species of birds produce them, how they are perceived by conspecifics, and the context in which they are produced. Difference Between Bird Calls and […]
Hard Disk Drive vs. Solid-State Drive
Hard disk drive or HDD and solid-state drive or SSD are two major types of data storage device. Take note that phonographic recording and optical discs, as well as DNA-based storage, are other types of storage mediums and technology. However, HDDs and SSDs are more popular because of their reasonable manufacturing cost and better storage […]
Newtonian Gravity vs. the Geometric Gravity of Einstein
There have been several theories postulated and formulated to define and explain the natural phenomenon now known as gravity. Two of these is the Law of Universal Gravitation introduced by Sir Isaac Newton in 1687 and the General Relativity Theory developed by Albert Einstein between 1907 and 1915. Note that Newton and Einstein had different […]
Why Is The Sky Blue: The Scientific Reason
The sky is not blue because it reflects the ocean. It does not work that way. If that is the case, then it does not explain why it remains blue when seen from a landlocked area within a vast landmass. Nonetheless, there is a simple scientific reason behind the color of the sky. The Scientific […]
