What is glass made from and why?

Answer 1

Because without it you wouldn't be able to see the pretty picture

Answer 2

glass is made from sand which they heat to make it transparent....... also right now the glass from anything in melting but so slowly that it will take about over 1 million years for it shrink considerably. sorry but i don't why is is made out of that. probably because sand is a solid and you can melt it to make it transparent.

Answer 3

Glass is usually used more for decoration and pizazz in an area or building. If it is used on a building, sometimes it is to make the building look larger and make the company look better and more profitable when in fact, it might not be.

Answer 4

It's not similar!

The popular view is that the atmosphere has some sort of layer of carbon dioxide "up there" that reflects heat back down to Earth rather than letting it escape to space. That would be like the glass on a greenhouse trapping warm air in while letting the sunlight through to increase the heat. In a greenhouse the sunlight warms the benches and floor, he warm objects heat the air, the air is trapped by the double layer of insulating glass.

It does not happen that way.

Sunlight comes in and warms the Earth's surface. It warms the gases in the air too, at least some of them with a bond size that gets excited by sunlight. These special gases are greenhouse gases (carbon dioxide, methane, water vapour and a few others). They are mixed evenly through all of the atmosphere (not in layer). When the gases are warm they share their heat with all their gas molecule neighbours and heat the atmosphere generally.

The effect is more like wet sand in a microwave. Microwaves do not heat sand. They do heat water. When you microwave wet sand, the water heats up - might even turn to steam. The hot water warms the sand.

Answer 5

Glass allows for the maximum anount of light available to enhance and promote plant growth. In addition it will allow heat to enter the area further helping plant growth

Answer 6

because its a glass house

Answer 7

sand
