Review Exam 2 1. Planet X has a radius 3 times larger than the earth’s radius. How does this planet’s volume compare to Earth’s volume? a. The volume is 3 times larger than the Earth’s radius. b. The volume is 1/9 the Earth’s radius. c. The volume is 27 times the Earth’s Radius. d. The volume is 1/27 times the Earth’s radius. 2. The moons X and Y orbit 2 different planets. They have the same orbital velocity, but the distance of X from its planet is 2 times the

the Earth's surface and atmosphere. It results from the fact that certain atmospheric gases, such as carbon dioxide, water vapor, and methane, are able to change the energy balance of the planet by absorbing longwave radiation emitted from the Earth's surface. Without the greenhouse effect life on this planet would probably not exist as the average temperature of the Earth would be a chilly -18° Celsius, rather than the present 15° Celsius. As energy from the Sun passes through the atmosphere a number

Composition Of The Atmosphere And The Effect Each Has On Climate? The Earth's atmosphere contains several different layers that can be defined according to air temperature. According to temperature, the atmosphere contains four different layers. The first layer is called the troposphere. The depth of this layer varies from about 8 to 16 kilometers. Greatest depths occur at the tropics where warm temperatures causes vertical expansion of the lower atmosphere. From the tropics to the Earth's polar regions

constantly rising into earth’s atmosphere and destroying the ozone layer causing global warming. The rise of the temperature on earth puts vegetation, marine life, and human life in serious danger. Generally, holes in the ozone layer are the cause of global warming which has catastrophic effects on our planet. The ozone is in two areas of earth’s atmosphere, the troposphere and the stratosphere. The role of the ozone layer is to absorb most of the UV radiation from reaching the earth’s surface that comes

climates in the future? How will these climate changes affect South-West Western Australia? How does climate change work? Climate change is a natural process that has been functioning on earth for billions of years, it is the regulator of the earth's abililty to support life by the cycles of The Greenhouse Effect. The Greenhouse Effect has made the earth an environment for supporting life through the cycling of energy from the sun via short-wave radiation, which heats the earths surface, then

Without our atmosphere, there would be no life on earth. Two gases make up the bulk of the earth's atmosphere: nitrogen (78%), and oxygen (21%). Argon, carbon dioxide and various trace gases make up the remainder. Scientists divided the atmosphere into four layers according to temperature: troposphere, stratosphere, mesosphere, and thermosphere. The temperature drops as we go up through the troposphere, but it rises as we move through the next layer, the stratosphere. The farther away from earth

The Changing Climate 1. “Earth’s climate has always been changing; it is the rate of change that is of current concern to scientists.” With reference to Figure 1, and other evidence which you have come across, discuss the validity of this statement. Firstly, global climate change is defined as “a change in the long-term weather patterns that characterize the regions of the world.” From Figure 1, we can see that the Earth’s climate has always been changing (at least temperature-wise),

The Earth’s climate is changing. Temperatures are rising, snow and rainfall patterns are shifting, and more extreme climate events—like heavy rainstorms and record high temperatures—are already taking place. Scientists are highly confident that many of these observed changes can be linked to the climbing levels of carbon dioxide and other greenhouse gases in our atmosphere, which are caused by human activities. There are a number of different forces which can influence the Earth's climate. When

believe that global warming is a normality of the earth’s atmosphere. This paper will answer the questions: who, what, why, when, and how global warming will or will not have a negative impact on human health. The research must start by describing global warming and why some scientist and researchers believe that it will have a negative impact on human health. In direct quotation of Bloice and Hallinan, 2005: The temperature of the earth’s atmosphere is influenced by the balance between the high
