The Greenhouse effect
Conduction is the transfer of heat through a material. Heat is transferred directly in and through the substance. Conduction heat loss or gain results from the transfer of heat directly through the materials of the building envelope. If the outside temperature is greater than the inside temperature, there is heat gain from outside the building.
Heat is primarily lost or gained through our windows or walls.
We speak of building materials as being poor or good conductors of heat.
Two objects must be touching for this transfer to occur.
Convection is the transfer of heat from particle to particle. It is the transfer of heat by the movement of fluids such as air or water. For example, the heated air around a stove will tend to rise to the ceiling. We all know hot air rises and cool air sinks. That is natural convection. Forced convection refers to the use of fans or pumps to move a fluid/air and the heat contained in it. We generally have forced-air furnaces in our homes.
Radiation is energy transmitted directly through space and does not require matter in transmission. All objects radiate energy or heat, which heats all cooler objects around it. Solar radiation passes through space to heat (and light) objects that it strikes. A person in a room with cold windows will radiate heat to them and that person will feel cool even if the air in the room is warm.

what effects could be seen if this trend continues. One of the reasons is called the ‘greenhouse effect’ where gases are trapped in the atmosphere. This in turn causes an increase in heat. This may (many have speculated) contribute to global warming which are problems that geologists continue to study and tackle. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gases…
Humans are a major effect to the climate such as the burning of fossil fuels and the conversion of land for forestry and agriculture. The amount of incoming energy and the amount of outgoing energy and can have both warming and cooling effects on the climate. The dominant product of fossil fuel combustion is carbon dioxide, a greenhouse gas. The overall effect of humans affecting the climate is carbon dioxide and enhanced by emissions of other greenhouse gases. The build-up of greenhouse gases in the…
The Victims The twigs from the trees scratch across our faces as we run for our lives. The coppery taste of blood mixed with my saliva lingers in my mouth as I try to escape; it feels like my heart is beating out my chest. The jungle is blurred around me, running at such a speed that my eyesight cannot steady. My limbs ache deeply, it feels like they could fall off at any moment. I see him stumble over, but none of us willing to stop and help. The sound of the cries from the people we had left behind…
Greenhouse effect killing our earth!? Since the industrial revolution, humans produce into the atmosphere , highly endothermic carbon dioxide and other greenhouse gases increased year by year, also increases the greenhouse effect of the atmosphere, has caused a series of serious problems such as global warming, caused countries around the world attention. In addition to carbon dioxide, an important role for the greenhouse effect gases as well as methane, ozone, chlorofluorocarbons and water vapor…
Carolyn W. Murphy Colorado Technical University SCI101-1204B-01 Introduction to the Sciences Phase 3 Greenhouse Effect Angela Edwards 1 In this research paper I will give you the definition of greenhouse effect, tell you how it works, and the gases that make up the greenhouse effect. I will also try to get you to see how the gases affect the world as a whole. Greenhouse effect occurs when gases in the atmosphere trap infrared energy from the sunlight and then the sunlight is then…
Earth Science Report: Green house Effect The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. since part of this re-radiation is back towards the surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases. Solar radiation at the frequencies of visible light largely passes through the atmosphere…
system and wildlife. This is because all kind of greenhouse gases can keep in the atmosphere at least a hundreds of years only will release all greenhouse gases and the increased warming on the climate will continuously very long times. 2.1Greenhouse effect impacts climate change to in Australia (a)Where do greenhouse gases come from to impact Australia? According to World Wind Fund for Nature (WWF) explained that the larger and highest of greenhouse gases producer is Australians, because of their…
Introduction A greenhouse is a glass building in which plants are grown that need protection from cold weather. The natural level of greenhouse gases in our atmosphere, which keeps the planet about 30ᵒC warmer than it, would otherwise be- essential for life as we know it. Water vapour is the most important component of natural greenhouse effect. Greenhouse gasses are gas that contributes to the greenhouse effect by absorbing infrared radiation. Some of the greenhouse gasses are carbon dioxide, nitrous…
the atmosphere stop some of the heat from escaping into space. These gases are called greenhouse gases and the natural process between the sun, the atmosphere and the Earth is called the 'Greenhouse Effect', because it works the same way as a greenhouse. The windows of a greenhouse play the same role as the gases in the atmosphere, keeping some of the heat inside the greenhouse. The Natural Greenhouse Effects The atmosphere has a number of gases, often in tiny amounts, which trap the heat given…
Global Warming Effect on the Earth By Tyler wood THE GREENHOUSE EFFECT -The greenhouse effect is something is the needed for humans to live. The greenhouse effect is in the atmosphere and it traps the UV waves and absorbs the energy. The energy that is trapped in the atmosphere is both absorbed and sent back into space. This action heats up the earth and keeps a layer of heat around the earth. The heat that is kept this layer is enough to heat earth during the night because the earth gets cold…
