Explain what characteristic of the water molecules allows it to dissolve ionic compounds (salts).
What is the average salinity of Earth’s ocean (in ppt)? What does parts per thousand (ppt) mean in terms of how much salt is present in 1 liter of seawater?
Describe what happens to the density of water: a)when pure water freezes b)at 4oC c)when water vapor condenses to liquid. d)when salt is dissolved
Explain how each of the following processes affects the salinity of seawater: a) Evaporation b) Precipitation c)Runoff from continents
Compare the salinity of the Mediterranean Ocean to the Eastern North Pacific Ocean (e.g. offshore of SoCal beaches). a) Do they have different salinities? b) Is the amount of seasalt the same? c)How do the proportions of major ions compare?

individuals who are not tracked slip under the radar. According to Ngai (2010), “it is now estimated that over 12 million people in the United States, over a third of the foreign-born population, is not in legal immigration status” (pg. 93). The United States has never been more proactive under the current administration in dealing with the problem with illegal immigration. In 2017, over 700,000 Mexicans were deported from the U.S. This number is enormous and for good reason, as “one hundred thousand removals is the worldwide total” (Ngai, 2010, p 98). Congress have prioritized this issue and increased Border Patrols budget immensely. The spending alone has tripled from 2003-2006 with an annual budget of just under 4 billion dollars. Honestly, the agency needs every cent as they are tasked with enforcing immigration laws and patrolling over 700 miles along the southern border. With the extra funding, drones have been utilized with infra-red and heat technologies. The number of CBP agents has also tripled to a congressionally mandated 21, 500; the number of ports of entries increased by thousands, and the number of ICE agents has tripled since 2016 (Cost, 2017, p 2). Unfortunately, even with all this attention to the southern border, it is not enough to deter immigration. On an average day, there is over 3 deaths along the border as a result of attempting to enter the U.S. illegally (The cost, 2017, p 1). Furthermore, congress has become more proactive in deportation and removal of illegal immigrants. So much that funding for the Customs Enforcement agency increased by eighty percent. With the increase in funding, more agents were added to the mission with “the number of apprehensions more than doubled and the number of interior removals increased by three-fold” (Amudeo and Lopez, 2017, p120). The increase in captures is identified as an increase in information sharing between apprehension and deportation of unauthorized immigrants which has since been a standard in every jurisdiction. One may ask why are so many people from Mexico attempting to risk everything and come to the United States? The answer is follow the money. The wages in the United States are over four times high on average than those in Mexico. Over the years, Border Patrol has changed immensely. As immigration laws change, they must adjust and enforce the new laws. As new Presidents come into office they also must accommodate their beliefs. The modernization of immigration enforcement has smart borders at the ports of entry in Canada and Mexico. Computers make life easier to include immigration enforcement. President Trump has a border wall on the table with Congress allocating over 2. 5 billion for border security to include construction of a physical wall which is seen as the most extreme version of an enforcement strategy to “to reduce illegal immigration in the United States” (Aiden, 2017, p 483). Today the Border Patrol has close to sixty thousand agents along the southern border. With the recent approval by President Trump to deploy the National Guard to defend the southern border, the security of the nation is increased. Deterrence has also played a valuable part in border security to thwart illegal immigration. With the U.S. ending the era of ‘catch and release’ it lets knows people who are considering committing the act that their actions can result in jail time and felony prosecutions. One argument however with the change in protocols and the multibillion-dollar wall is wheth>GET ANSWER
