  What Is Climate Change? Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s,  human activities have been the main driver of climate change , primarily due to burning fossil fuels like coal, oil and gas. Burning fossil fuels generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures. Examples of greenhouse gas emissions that are causing climate change include carbon dioxide and methane. These come from using gasoline for driving a car or coal for heating a building, for example. Clearing land and forests can also release carbon dioxide. Landfills for garbage are a major source of methane emissions. Energy, industry, transport, buildings, agriculture and land use are among the  main emitters . Greenhouse gas concentrations are at their highest levels in 2 million years And  emissions contin

  Difference Between Mass And Weight   The  difference between mass and weight  is that mass is the measurement of how much matter is contained within an object whereas weight is a measurement of how much gravity is pulling down on an object. Hence, on the moon, you will have the exact same mass as on Earth, but you will have a much lower weight due to the weaker gravitational pull from the moon compared to the Earth. Science involves numerous different theories, laws, and concepts that work together to form a comprehensive view of the world around us and beyond. The scientific concept of things is used to classify and create a structure for scientists to work with. “From birth, man carries the weight of gravity on his shoulders. He is bolted to earth. But man has only to sink beneath the surface and he is free.” — Jacques Yves Cousteau For instance, when we look at something moving really fast, how do we define what fast is? For that, we use concepts like acceleration and velocity to

  Difference Between Gravity and  Weight Gravity vs Weight Gravity and weight are two concepts involved in the gravitational field theory of physics. These two concepts are often misinterpreted and used in the wrong context. It is vital to have a better and correct understanding of gravity and weight, if one is to excel in science. These two are almost similar concepts that are used interchangeably. However, we will see here, that gravity and weight are not the same. In this article, we are going to discuss what gravity and weight are, their basic concepts, applications, similarities and finally their differences. Gravity Gravity is the common name given to the gravitational field. Gravitational field is a concept and a method for calculating and explaining phenomena happening around any object with a mass. A gravitational field is defined around any mass. According to Newton’s universal law of gravitation two masses M and m separated by a finite distance r exerts a force F = G M m / r

Facts About Gravity for Kids   Gravity is one of the four fundamental forces of nature, without which the universe would be unrecognizable. Gravity is the weakest of these four forces, but it is important to life on Earth and the structure of the universe. Everything that has matter generates gravity, from a grain of sand to the largest objects in the universe. That gravity pulls things together. Size Matters When it comes to gravity, the larger an object is, the stronger its force. A person creates gravity but not enough to pull objects toward him or cause things to go into orbit around him. On the other hand, a planet has enough gravity to pull objects into orbit around it. A star makes enough gravity that it can pull whole solar systems into its orbit, like ours. Our sun's gravity is so strong that it keeps an object -- Pluto -- that is roughly 3.7 billion miles away in orbit. Gravity Keeps the Moon in Place The Moon is in orbit around Earth. That means that it circles Earth wit

Gravity: You don't know what you've got 'til it's gone      Here on Earth, we take gravity so for granted that it took an apple falling from a tree to trigger Isaac Newton's theory of gravitation. But gravity, which draws objects together in proportion to their mass, is about much more than fallen fruit. Read on for some of the strangest facts about this universal force. It's all in your head Gravity may be pretty consistent on Earth, but our perception of it isn't. According to research published in April 2011 in the journal PLoS ONE, people are better at judging how objects fall when they're sitting upright versus lying on their sides. The finding means that  our perception of gravity  may be less based on visual cues of gravity's real direction and more rooted in the orientation of the body. The findings may lead to new strategies to help astronauts deal with microgravity in space. Coming down to Earth is tough Speaking of astronauts, their experi
