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 …
Clouds are composed of ice crystals or water drops suspended and drifting in the sky at considerably high altitudes. The water droplets are very minute with a diameter of roughly a hundredth of a millimeter. This means that each cubic meter of air is made up of about 100 million droplets. The composition of ice …
Biomes are a group of ecosystems sharing the same characteristics and are well adapted to the prevailing abiotic factors. Any earth surface that has got a very large ecological system characterized by dominant forms of plant and animal life forms adapted to the prevailing climate and other environmental factors is termed as a biome. Biomes …
The earth is technically the 3rd planet from the sun between Venus and Mars and has an equatorial diameter of 12,755 kilometers (7926 miles) and a polar diameter of 149.6 million kilometers (92.9 million miles). The earth is in a constant state of motion as it revolves round the sun, which takes a period of …
