If this is a true or false question, the answer is false. United States do share land borders with Mexico as well as Canada along with Russia, Bahamas and Cuba. United States then is north of Canada and south of Mexico. Hope this is the answer.
South Africa's location makes it a key spot for renewable energy in the forms of wind, hydroelectric and solar, as it is on the peninsula of the continent it has access to many of these rich resources. There is also a great deal of industry in South Africa, particularly in the mining of metals, as one of the country's largest exports. This extraction uses huge amounts of energy in the process and most of this equipment used in the extraction pumps toxic gases and chemicals into the atmosphere, if SA uses more renewable energy sources, the levels of pollution will decrease.
It looks like you should draw where the moon is orbiting the earth and wheee the earth is relative to the sun during that tide.
