Introduction Nuclear energy is the type of energy produced by a process known as fission. Electricity is generated in several ways such as using solar panels, coal burning, or maybe by capturing the heat from atoms that split apart. If electricity is produced from splitting atoms apart then it is called nuclear energy. Thermal power […]
What is Solar Energy? – Uses, Advantages, Disadvantages
Introduction For billions of years, energy has been produced by the sun. Solar energy is the sun’s beams (solar radiation) that reach the earth. This solar energy can be converted into different forms of energy like heat and electricity. In the 1830s, a solar thermal collector box (a device that collects sunlight to gather heat) […]
What is Wind Energy? – Uses, Advantages, Disadvantages
Introduction Wind energy is a transformed form of solar energy that is created in its core by the nuclear fusion of hydrogen (H) into helium (He). The H-He fusion reaction generates heat, and electromagnetic radiation pours out from the sun in all directions into space. Despite the fact that just a small percentage of solar […]
Need for Trees in Karachi – Importance and Benefits Of Trees
Why Does Karachi Need Trees? Trees are an essential aspect of the ecology, which is badly lacking in mega-cities like Karachi. Trees provide cooling by transpiring water from the earth, via the roots, and out of their leaves. Furthermore, trees give shade. Those who have experienced Karachi heat on the streets and compared the temperature […]
What Are Phytoplankton And How They Benefit Our Environment?
Introduction: Phytoplankton is a combination of two Greek words Phyto means plant and Plankton mean to make a drift. They are found in both salt water and fresh water. These are microscopic plant-like organisms and also make their food by capturing sunlight and converting it into energy. Some of them get more energy by consuming […]
Glacial Lake Outburst Floods in Pakistan- Causes and Effects
Introduction Glaciers in Pakistan’s northern mountain ranges (the Hindu Kush, Himalayas, and the Karakorum) are melting quickly due to rising temperatures, and a total of 3,044 glacial lakes have formed in Gilgit-Baltistan (GB) and Khyber Pakhtunkhwa (KP). Of them, 33 glacial lakes have been identified as being vulnerable to dangerous glacial lake outburst floods (GLOF). […]
How To Prevent Hazardous Monsoon Season Flooding in Pakistan
Introduction: The monsoon season continues to cause problems in various regions in Pakistan, generating floods, flash floods, and other severe weather-related catastrophes, as well as increasing humanitarian needs. According to the National Disaster Management Authority (NDMA), up to 147 fatalities have been recorded throughout the country as of 11 July,2022. More than 1000 dwellings have […]
Karachi Monsoon Urban Flash Flooding – Causes and Impacts
Introduction: A flash flood is induced by a large amount of rain in a short period, usually less than 6 hours. Flash floods are typically defined by violent torrents that burst over river beds, metropolitan streets, or mountain valleys, sweeping everything in their path. Flash floods in urban areas are also known as urban flooding. […]
National Parks in Pakistan – Fauna, Flora and Importance
Introduction: A national park is not the typical park with fences, swings, and gardens. A national park is often a government-owned land reserve. Its principal goal is to preserve and conserve endangered species of flora and animals. There are approximately 6,555 national parks worldwide. There are 21 parks in Pakistan out of a total of […]
Glacier Melting and Glacial Retreat – Causes, Effects, Solutions
INTRODUCTION Glaciers are massive quantities of ice that move downward slowly. Wherever snow accumulates faster than it melts, a glacier forms. When melting outweighs accumulation, it retreats—that is, its terminal edge, the end of the glacier tongue, terminates at progressively higher heights. Since around 1850, the majority of the world’s mountain (alpine) glaciers have been […]
