Answer:
In this unit, we will be discussing Latitude as a climatic control. By latitude we are not talking about geographic location. Rather our interest will center on the effect of latitudinal location on the receipt of solar energy at the Earth's surface. To a degree the Greeks were on to the idea when they proposed their Torrid, Temperate and Frigid temperature zones over 2000 years ago.
02. Specifically in this section on Latitude, we are going to cover four topics:
Earth-Sun Relationships. This section will deal with the actual receipt of solar energy at the Earth's surface. The receipt of solar energy is directly related to the relationships which exist between the Earth and the Sun across the year. All of you would recognize the basic relationships. Each day we can see that the Sun "rises" in the east and sets in the west. Most would also recognize that over a 12 month period the Sun "moves" from north to south in our sky. In other words, the Sun not only "moves" from east to west, but also north to south. And how about the fact that days tend to get longer in the northern hemisphere from December 21 to June 21, and then grow shorter from June 21 to December 21? Earth-Sun relationships cause changes in the amount of insolation received day to day and seasonally. And, depending upon the relationship, the amount of insolation changes locationally and through time. The resultant temperatures created due to these changing relationships create pressure differences which are largely responsible for winds. The winds in turn drive the ocean currents and our weather.

In 2010, the Soufriere Hills volcano on the Caribbean island of Montserrat erupted violently, spewing huge clouds of ash and gases into the sky. How do the volcanic eruptions at the end of the Permian period and the formation of Pangaea, both of which occurred about 252 million years ago, set in motion events that altered evolutionary history
Answer and Explanation:
Pangaea is the term used to describe the supercontinent that existed millions of years ago, before the continents were spread across the globe as we know it today. The separation of continents occurs due to the rapid convections of the Earth's mantle. These mantle convections increased volcanic activity on the earth, making volcanism very active and causing numerous volcanic eruptions, which increased the concentration of carbon dioxide in the atmosphere, increasing the greenhouse effect and creating a long period of intense global warming.
It was this global warming that altered the evolutionary events on earth, promoting a strong natural selection of plants and animals, which even led to the creation of new species and extinction of old species, in addition to creating a geographical and environmental modification.
La Soufriere Hills volcano is a group of active volcanoes. The volcanic eruptions altered the climatic conditions and led to natural selection.
What is Pangaea?Pangaea was used to describe the supercontinent that existed millions of years ago before the separation of the continents present now. The rapid convections in the mantle of the Earth caused the shift and drift in the tectonic plates.
The movement of the tectonic resulted in increased volcanic activities that caused numerous volcanic outbreaks resulting in increased carbon dioxide concentration in the environment.
This led to global warming and resulted in a change in climatic conditions. Global warming altered the evolution of the organisms through the process of natural selection and led to the extinction and the introduction of species.
Therefore, volcanic eruptions and Pangaea resulted in environmental and geographical alterations.

Answer:
Is that a diffrent languge
Explanation:
Japan, China and the US are the top 3 consumers of seafood and 1.2 billion people depend on seafood as their daily source of protein. However our fishing stocks have decreased by 90% between 1950 and 2011. In addition, certain commonly used fishing practices cause horrendous damage to the rest of ocean ecosystems. A study in 2006 estimated that, if fishing continues at the current rate, all the world's fisheries will have collapsed by the year 2048.
What might be causing greater and greater demand for seafood?Why do you think we have seen a dramatic increase over the last 50 years in how many fish we are able to catch?
Answer:
Explanation below
Explanation:
Asia and the Pacific region have continued to remain the world's largest producer of fish. Various researchers have identified certain benefits of consuming seafood, which have caused greater demand for them. Apart from being ideal source of vitamins, fish is also rich in Omega 3 fatty acids, which can help prevent high blood pressure, cancer and heart diseases. Seafood also strengthen the immune system through their antioxidants.
Rapid advances in fishing technology have led to the dramatic increase over the last 50 years in how many fish we are able to catch. Most people in the fishing business now use factory ships, in place of fishing vessels. These ships are can stay at the sea for several weeks and they have all the necessary equipment that can be used to either freeze of tin fish that they catch using their hunting ships.
The factory ships need to get full before they can return to base and this has caused over a 7% growth in catches every year.

What is “restricted trade?”
Explanation:
Trade restrictions are typically undertaken in an effort to protect companies and workers in the home economy from the competition by foreign firms. A protectionist policy is one in which a country restricts the importation of goods and services produced in foreign countries.
The main types of trade restrictions are tariffs, quotas, embargoes, licensing requirements, standards, and subsidies. A tariff is a tax put on goods imported from abroad. The effect of a tariff is to raise the price of the imported product. Revenue tariffs are put in place to raise money for the government.

1.) What is a brief history of the island of Jamaica. Beginning with the native Indian population and going through Spanish exploration to the introduction of Africans, to modern day.
Answer:
Explanation:
The original inhabitants of Jamaica are believed to be the Arawaks, also called Tainos. They came from South America 2,500 years ago and named the island Xaymaca, which meant ““land of wood and water”. The Arawaks were a mild and simple people by nature.
The name Jamaica is derived from Xaymaca, the Taíno-Arawak name for the island, which translates, as 'isle of springs'. Jamaica was charted by Christopher Columbus during his second voyage and the first Europeans to arrive on the island were the Spanish in 1509.
The first Africans to arrive in Jamaica came in 1513 from the Iberian Peninsula. When the British Empire captured Jamaica in 1655, many of them fought with the Spanish, who gave them their freedom, and then fled to the mountains, resisting the British for many years to maintain their freedom, becoming known as Maroons
