[o.01]the diagram below shows some ocean floor features. picture shows the following features of the ocean floor. continent: the landmass surface where the water from the ocean meets at the shoreline, continental shelf: the edge of a continent where the water is relatively shallow, continental slope: a sharp drop in depth where the ocean basin truly begins and the continental crust ends, volcanic island arc: a line of volcanic islands caused by subduction and the melting of either oceanic or continental crust, abyss: the deepest portions of the ocean basin, excluding ocean trenches, mid-ocean ridge: the location where sea floor spreading occurs, abyssal plain: a large, flat, and deep portion of the ocean surrounding either side of a mid ocean ridge, guyot: a large, flat-topped, underwater volcano, ocean trench: an extremely deep portion of the ocean, similar to a canyon, formed during subduction, seamount: an underwater mountain. the mid ocean ridge is labeled as a. which of these statements is correct about the feature labeled a in the diagram? it is an underwater basin caused by subduction. it is a deep trench located on both sides of a mid ocean ridge. it is the part of the ocean floor where new crusts are formed. it is the portion of the ocean floor where old crusts are eroded.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.

the electromagnetic energy from the sun arrives in the form of visible and invisible light.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
