In the simplest terms, energy is the ability to do work. Energy is also represented in terms of any source of usable power. In different ways, energy is used to do almost everything such as jumping, walking and the operation of machinery. For instance, the foods human consume contain energy which is stored in the…
The earth is the 3rd planet from the sun between Venus and Mars. The earth is made up of several unique properties, characteristics, composition and they all affect the processes of the earth differently. Every of these properties and elements in Earth’s system are largely categorized into one of the four major subsystems including water,…
Rainforests are the forests characterized with tall trees, relatively warm climates and a great degree of rain on an annual basis. Most rainforests have an annual rainfall in the ranges of 250 to 450 centimeters (98 to 177 inches). In ecological explanation, rainforests are defined as “multi-storied closed, broad leaved forest vegetation with a continuous…
This short, informational list creates new awareness on the need to protect your local coral reefs, whether they are simply visible as small rock pools or part of the listed natural wonders of the world. In all cases, the protection of these natural habitats of small flora and fauna, barely visible or unseen, is vital…
Up to the present time, when it comes to discussions about the earth’s surface cover, most of it is covered by water. About 70% of the entire earth’s surface is overlaid with water, most of which are the oceans. Out of the total water surface on earth, more than 96% is the ocean’s salty water….
The planet earth is made up of vast landmasses, which makes up where all human beings live. Among all the planets in the solar system, the earth offers the most diverse landmass features. These landmasses are known as continents covering 1/3rd area of the planet. According to the Pangaea Theory, the earth was originally one…
The oxygen cycle elaborates how oxygen circulates in various forms through nature. Oxygen occurs freely in the air, trapped in the earth crust as chemical compounds, or dissolved in water. Oxygen in the atmosphere is about 21%, and it is the second most abundant gas after nitrogen. It is mostly utilized by living organisms, especially…
Ecosystem is the interconnectedness of organisms including animals, plants, and microbes with each other and their non-living environment. Examples of the non-living aspects of the environment include climate, soil, water, sun, earth, rocks, atmosphere, temperature, and humidity. In an ecosystem, every living organism has an ecological niche. Hence, what makes an ecosystem is the complex…
There are various types of pollution i.e. air, water, land, noise, industrial, soil, light, thermal etc. and they are categorized based on the region of the environment which they negatively impact, contributing to the multiple causes of pollution. Accordingly, each and every type of pollution has its own distinguishing causes and environmental effects. Understanding pollution…
Rocks ordinarily lie everywhere on the ground of the earth. They constitute most of the landforms, as we often notice. For instance, rocks make up the mountains and most of the non-water portions of the earth’s surface. A rock is hence defined as a solid naturally occurring mass or lumps of consolidated mineral matter that…
Biomagnification stands for Biological Magnification, which means the increase of contaminated substances or toxic chemicals that take place in the food chains. These substances often arise from intoxicated or contaminated environments. The contaminants include heavy metals namely mercury, arsenic, pesticides such as DDT, and polychlorinated biphenyls (PCBs) compounds which are then taken up by organisms…
Eutrophication is characterized by dense algal and plant growth owing to increased concentration of chemical nutrients needed for photosynthesis. It mainly arises from the oversupply of phosphate and nitrate nutrients. As such, increased levels of chemical nutrients from animal waste, fertilizers and sewage often give rise to eutrophication when washed into nearby surface waters by…
The Pacific Ring of Fire is the terminology given to a u-shaped area that is almost forming a ring or a circle in the Pacific Ocean expanding all the way from South America and North America to Eastern Asia, New Zealand and Australia. The stretch is approximately 40,000 kilometers (25,000 miles) from New Zealand, all…
Landforms are the natural properties and shapes prevalent on the earth’s surface. These basically consist of the solid parts of the planet which start from the mountains and end in the ridges in the ocean. That means, everything in between are different types of landforms. With diverse physical characteristics, landforms are spread throughout the planet….
Wind can be defined as air currents or moving mass of air from high-pressure areas to low-pressure areas. Typically, air under high pressure normally moves towards areas under low pressure. Thus, the greater the pressure difference, the faster the flow of air which creates moving air with a considerably strong force. The bulk movement of…
