With close reference to the extract‚ show how J.B. Priestley creates mood and atmosphere for an audience here. Priestley‚ in ‘An inspector calls’‚ creates mood and atmosphere for an audience‚ in the extract‚ by using stage directions and writing how the character is talking. ‘(Bitterly)’ or ‘(with authority)’ shows that the character who is talking is talking with a certain tone in his/her voice and this makes the audience think that the person‚ who is talking‚ is trying to get the other person

warming refers to the rise in the average temperature of the atmosphere due to the effect of greenhouse gases. Greenhouse gas is a gas in the atmosphere that is been absorbs and emits it radiation at infrared range. The fundamental process of this act causes the greenhouse effect. The greenhouse effect is a process where atmospheric greenhouse gases are been re-radiated into the atmosphere. The most abundant greenhouse gases in the atmosphere are; • Water vapour • Carbon dioxide • Methane • Ozone

1. An atmosphere (New Latin atmosphaera‚ created in the 17th century from Greek ?tµ?? [atmos] "vapor"[1] and sfa??a [sphaira] "sphere"[2]) is a layer of gases surrounding a planet or other material body of sufficient mass[3] that is held in place by the gravity of the body. An atmosphere is more likely to be retained if the gravity is high and the atmosphere’s temperature is low. Earth’s atmosphere‚ which contains oxygen used by most organisms for respiration and carbon dioxide used by plants‚ algae

natural contributor to global warming‚ and lasts about nine days in the atmosphere. Water vapor is in the atmosphere more recently‚ because there has been more water that has evaporated because of the hotter temperatures. Water vapor increases as the earth’s atmosphere warms‚ but so does the possibility of clouds and precipitation. Bigger and more dangerous storms have been occurring recently due to the warm water vapor in the atmosphere.

emitted by the atmosphere and absorbed by the ground. Let’s look at this in more detail. The energy flows between the surface‚ atmosphere‚ and space. Some of this radiation is reflected back to space‚ but much is absorbed‚ warming the surface. Meanwhile‚ the Earth’s surface emits long-wave radiation upwards. Some of this radiation escapes directly to space‚ while the remainder is absorbed by the atmosphere. What about long-wave radiation emitted by the atmosphere? Although the atmosphere is colder

and‚ to a lesser extent‚ oceanic circulation) is the heat we receive from the Sun‚ termed solar insolation. The spectrum of light which comes from the Sun is shown above. The spectrum of light in the atmosphere and at the Earth’s surface is shown below. Insolation arrives at the edge of our atmosphere primarily as short wavelength radiation (179 kcal/cm2/yr). The amount of insolation which reaches the Earth’s surface depends on site latitude and season. Imagine a disk in front of the Earth that is

gas giant planets. The density is lower than any of the four terrestrial planets. Jupiter’s upper atmosphere is composed of about 88–92% hydrogen and 8–12% helium by percent volume or fraction of gas molecules. Since a helium atom has about four times as much mass as a hydrogen atom‚ the composition changes when described as the proportion of mass contributed by different atoms. Thus the atmosphere is approximately 75% hydrogen and 24% helium by mass‚ with the remaining one percent of the mass consisting
