How do everyday activities like driving a car and using electricity lead to global warming ?

Answers

Both driving a car and using electricity produce several greenhouse gases which can lead to global warming.Greenhouse gases are gases that, when released into the atmosphere, trap the heat from the sun's energy. Every day the energy from the sun reaches the earth. Some of the energy is reflected back into space and some of the energy is trapped by the earth's atmosphere. Most of the time the energy being trapped by the atmosphere serves to warm up the earth, so that the temperature does not fluctuate dramatically. In this way the atmosphere acts like a greenhouse - trapping the warmth in. One of the ways that electricity is made is by burning fossil fuels, like coal or fuel. When a fuel is burnt, some of the products are: carbon dioxide, carbon monoxide, and water - all of these gases are greenhouse gases. In a similar way driving a car also burns fossil fuels, and this will produce the same gases.Before lots of fossil fuels were burnt the greenhouse gases in the atmosphere would have been moderated by the carbon cycle. However, if we burn excess fossil fuels we are producing excess greenhouse gases. This can cause more heat to be trapped by the atmosphere and therefore the global temperature will start to rise - global warming. hope i helped

HOW DO MATTER, ELEMENT, ATOM,CRYSTAL, COMPOUND, and MOLECULE, RELATE?

Answers

They're all intertwined! For instance: Matter is composed of Atoms - which are kept together and create molecules.  Elements are made up of only one kind of atoms.  Atoms that have different elements and are bonded together form compounds. If atoms are ever aligned in a perfect 3d arrangement, they form an awesome crystal.

So in short: They all are one big happy family, so to speak that are either the outcome or help decide the outcome of the product.
Atoms make up everything around us including us and they also make up matter. Elements are Earth, Wind, Fire and Water.
