What are the Clouds, How Do They Form and Different Types of Clouds

What are the Clouds, How Do They Form and Different Types of Clouds

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…

What is a Biome and What are Major Types of Biomes on Earth?

What is a Biome and What are Major Types of Biomes on Earth?

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…

What are the Different Layers of The Earth?

What are the Different Layers of The Earth?

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…

Causes, Effects and Solutions to Water Scarcity

Causes, Effects and Solutions to Water Scarcity

Water scarcity or water crisis or water shortage is the deficiency of adequate water resources that can meet the water demands for a particular region. Whenever there is a lack of access to potable and fresh water for drinking and sanitation, the situation means that the water is scarce. Water scarcity thus pertains to a…

What is Weathering and Different Types of Weathering

What is Weathering and Different Types of Weathering

Rocks, minerals, soils normally change their structure under the action or influence of certain environmental forces. Biological activity, extreme weather, and agents of erosion such as water, wind and ice are examples of environmental forces that influences the continuous breakdown, wearing away and loosening of rocks and soils. This is what is termed as weathering….

What is Ecological Footprint and Ways to Reduce it

What is Ecological Footprint and Ways to Reduce it

Ecological footprint is a terminology that attempts to gauge the extent of human impact on the earth’s ecosystems. There are many ways humans deplete environment capital just from our basic lifestyles to resource exploitation, environmental degradation, and pollution. As our consumption increases due to overpopulation, it is important for us to measure nature’s capacity to…

Types and Principles of Plate Tectonics Boundaries

Types and Principles of Plate Tectonics Boundaries

Plate tectonics defines the movements and features of the Earth’s surface now and in the past. The theory of plate tectonics was advanced in the 1960s and 1970s to generate new information about the Earth’s ancient magnetism, the nature of the ocean floor, the flow of heat from the Earth’s interior, and earthquake and volcanic…

Metamorphic Rocks: Formation, Types and Examples

Metamorphic Rocks: Formation, Types and Examples

Metamorphic rocks are the rocks formed from other rocks. They are sedimentary or igneous rocks that have undergone changes as a result of extreme pressure and heat. The name defines their formation whereby ‘meta’ means change and ‘morph’ means ‘form.’ Hence, metamorphic rocks are those whose forms have been changed through a geological process such…

Sedimentary Rocks: Formation, Types and Examples

Sedimentary Rocks: Formation, Types and Examples

Sedimentary rocks are the most common rock types which are freely exposed on the earth’s surface. They are formed from other rock materials since they are made up of the buildup of weathered and eroded pre-existing rocks. The weathering, erosion and the eventual compaction of igneous, metamorphic or formerly structured sedimentary rocks among other biological…

Igneous Rocks: Formation, Types and Examples

Igneous Rocks: Formation, Types and Examples

Igneous rocks form from the cooling of magma – molten materials in the earth’s crust. The terminology Igneous means fire or heat. In this sense, igneous rocks are formed when molten rock (magma) solidifies either underneath the earth’s crust to form plutonic (intrusive) igneous rocks or on the surface of the earth to form volcanic…

Trophic Levels and Energy Flow in a Food Chain

Trophic Levels and Energy Flow in a Food Chain

In all ecological communities, living organisms feed to get the energy that sustains their growth, movement, and reproduction. Accordingly, communities of organisms have to feed on each other creating a system whereby each organism is eaten and, in turn, it is eaten by another organism. This system is what is widely known as food chain….

What is a Food Chain and What is a Food Web?

What is a Food Chain and What is a Food Web?

Food chain and food web represent how living organisms feed to get the energy that sustains their growth, reproduction, and movement in their respective ecological systems. It is because the various communities of organisms in an ecosystem have to feed on each other to survive. This feeding relationship in the ecosystem is thus what brings…

Why is Biodiversity Important and Reasons For Loss of Biodiversity

Why is Biodiversity Important and Reasons For Loss of Biodiversity

Biodiversity is the variety within and between animal and plant life in a particular habitat or the entire planet. In any particular region on the planet, there are numerous different species. A small-scale example of biodiversity is the various life forms within the park in the neighborhood. Examples of diverse species locally include butterflies, trees,…

What is Ecology and What are Various Ways to Protect Ecology

What is Ecology and What are Various Ways to Protect Ecology

Ecology is an intricate biological subject that deals chiefly with the relations between organisms, including humans, and the environmental elements that affect them. For instance, ecology helps the world understand how microscopic bacteria grow in water, how animals and plants interact and survive in the seas, deserts, forests or land and the list goes on….

15 Wonderful Ways to Reduce Carbon Footprint

15 Wonderful Ways to Reduce Carbon Footprint

Since the great era of industrialization and mechanization of machinery for transport and manufacturing, the rate of greenhouse gas emission has gradually increased, and it became even worse in the 20th century. Use of fossil fuels has been the biggest driver of the earth’s total greenhouse gas emissions, leading to an increase in the amount…
