Troposphere

Group Members: Dustin Ballard Caroline Fraser Thomas Lichtenberger Brandon Mendoza Project Rough Draft SOURCES COUNT: (7/10 minimum) With the increase in humans populating the planet, there comes a need for more and more resources, as well as more highways for transportation, leading to more cars on the road, and ultimately more greenhouse gas emissions. Greenhouse gas activity is obtained by subtracting the long wave radiation which escapes the earth from the estimated radiation emitted by the

The Cretaceous-Paleogene Mass Extinction Wil Creasy Student Number: 20921355 The Cretaceous-Paleogene boundary (K-Pg boundary) was host to one of the three largest mass extinctions in the past 500 million years. Evidence suggests it was the result of a large asteroid impact approximately 65.5 million years ago in Chicxulub, Mexico; hence why the crater it formed was named the Chicxulub crater. The crater was approximately 180 kilometres in diameter and was believed to have led to the extinction

Associate Level Material Oceans and Atmosphere Worksheet Using the assigned readings for Week Six, prepare a 50- to 75-word response to each of the following questions. The Oceans 1. What is the composition of seawater? The salinity of seawater ranges from 3.3 to 3.7%. When seawater evaporates it leaves behind sodium chloride, better known as table salt. The other components of seawater are acquired through various methods. One of which is weathering. Chemical weathering of rock releases

Chapter 3 Reading Questions: 1. Core Case Study: “Have you thanked your insects today?”- Explain why insects are significant. Many of the earth’s plant species depend upon insects to pollinate them. Carnivorous insects, such as the praying mantis, control the ‘pest’ insect population. 2. What percentage of the species on this planet consists of insects? Animals? Plants? 53% are insects; 20% are other animals; 18% are plants. 3. Give three examples of how we benefit from microbes. Soil bacteria

David Gonzalez ENVS 1042 Test #2 1. Thermohaline Circulation: Thermohaline circulation, often referred to as the ocean 's "conveyor belt", is a worldwide current system in which warmer, fresher water moves along the surface and colder, saltier water moves deep beneath the surface. Deep ocean currents are caused by differences in water density. Colder, saltier water is denser and sinks while warmer, fresher water is less dense and rises. Temperature of seawater is affected by heat from the sun and

Synopsis: Astronauts are travelling to Venus. This is the first human mission ever to visit Earth’s sister planet. They must survive a many month journey in cramped quarters, and that isn’t even the difficult part. It is necessary for them survive on the surface of Venus as well. The second planet in our Solar System is not a hospitable place. The crew will have to face the challenges of Venus’s high winds and violent storms, the crushing air pressure, and more. Using the Russian Venera missions

appearance confirms that the planet's atmosphere is composed almost solely of one element, methane gas. There is a preponderance of haze, composed of ethane and other hydrocarbon ices high in the stratosphere, and clouds of methane ice low in the troposphere. The cloud particles constantly recycle themselves, first creating then destroying the heaviest crystals. This is an indication that Uranus' atmosphere is still evolving from its formation out of the solar nebula. Because Uranus lies on its

have seen the largest increase in warmth (Easterling & Karl, 2011, para6). Further, the hottest years recorded since instrument recording of temperatures became possible were from 1995 to 2006. Plus, new measurement analysis of the lower and mid-troposphere show comparable temperature rising rates as surface temperatures (Alley et al., 2007, p.5). Also, in this past century the arctic temperature average has doubled in comparison to the global temperature average (Alley et al., 2007, p.7). In addition

There is helium, molecular hydrogen, methane, and some ammonia. Earth’s atmosphere is made up of nitrogen, oxygen, argon, carbon dioxide, and water vapor. There are four main layers to Earth’s atmosphere. They are the troposphere, stratosphere, mesosphere, and thermosphere. The troposphere is the closest to the surface. The temperatures decreases as the altitude increases. The pressure decreases as altitude increases also. This is the only part where there is weather. The stratosphere contains the ozone

“Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive non metal and oxidizing agent that readily forms oxides with most elements as well as other compounds.”By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to found dioxygen, a colorless and odorless diatomic gas with the formula O2. This is
