ATMOSPHERE, WEATHER AND CLIMATE4Examine the figures below. Contrast the role the greenhouse effect plays in the atmospheres of (a) the Moon, (b) Earth, and (c) Venus.
ATMOSPHERE, WEATHER AND CLIMATE5Greenhouse effect can be interpreted in simple terms as the amount of greenhouse gases (majorly CO2) that surround a planet allowing enough energy from the sun to be retained hence keeping the planet at its relevant temperature (Tarbuck, Lutgens, & Tasa, 2014). The presence of the greenhouse gases also determines the atmospheric pressure in a planet. The greenhouse effect on Venus compared to the green house effect on Earth contrast sharply. The role of greenhouse in planet Venus increased the heat to 462 degrees C while the enough of it keeps earth temperature at a moderate temperature of 16 degrees with the highest temperature not exceeding 70 degrees C (Tarbuck, Lutgens, & Tasa, 2014). The lack of greenhouse can equally lead to very cold temperatures. In Venus, the greenhouse gas is mainly CO2 and so it traps 99% of all the heat emitted by the planet’s surface making the planet’s temperatures hot and the atmospheric pressure very high even on the parts of the planet that are not directed towards the sun. When compared to earth, the earth only has a limited amount of CO2 and other greenhouse gases, making the earth able to trap only enough heat emitted from the surface of the earth. The lack of greenhouse effect on the moon creates a bigger contrast form the two planets-Venus and earth (Tarbuck, Lutgens, & Tasa, 2014). The Moon which is considered to be equal in distance from the sun, like the earth is, has a temperature of 230 degrees F when the sun is shining and drops to -290 degrees F when it is dark. Meaning that, lack of greenhouse causes the imbalance in temperature in the moon, which in turn explains why the moon has no atmosphere.
ATMOSPHERE, WEATHER AND CLIMATE6Question 10 Compare and contrast weather and climate and how the atmosphere affects both.Even though these two words - weather and climate are often used interchangeably to mean the same thing, the two are quite different and have a huge contrast. The key contrast between the two words is caused by time as a factor. This can be best understood form the definition of the two words (Gartland, 2014). While weather is defined as the day-to-day state of the atmosphere in a region, climate is the statistical weather information that describes the weather variation at longer interval. Therefore the difference between weather and climate is a measure of time. Another contrast is in the components. The aspects of weather include sunshine,
