Since there is no map posted, I will tell you the location of Colombia, and hopefully you can figure it out.
Colombia is a country in South America. It is one of the two countries that occupies the northern part of the continent. Colombia is on the western (left on the map) half of the northern part of the continent. It is a country that comes out on both, the Caribbean Sea, and the Pacific Ocean. On its northeastern part it has a border with the country of Panama, on its eastern side with Venezuela, Brazil on the southeast, Peru on the south, and Ecuador on the southwest.
I'm pretty sure its C. sonar.
B.) a population density map and c.) a political boundary map
The neap tide is tide that occur when sun,earth and moon are positioned to form a right triangle in space.The sun,earth and the moon form a right angle and the gravitational pull of the sun counteracts the pull of the moon.This neap tide occurs when the difference between high and low tide is least. In addition the neap tide comes twice a month,in the first and third quarters of the moon.
