The Atlantic Ocean is shaped

The Atlantic Ocean is S shaped.

Explanation:

The Atlantic Ocean is the body of water between Africa, Europe and the Americas. In the south, it extends as far as Antarctica, where it borders the Southern Ocean. It is the second largest of the world's five oceans.   Its total area is about one-fifth of the earth's surface. It stretches in an S-shape from Iceland up to 58° south latitude for about 11,300 km.

Most of the most developed countries in the world lie on the shores of the North Atlantic. The Atlantic Ocean is thus interwoven with a network of the world's most widely used sea routes between the Eastern and Western Hemispheres.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.        

hygrometers and hair thermometers (often found as part of hygrometers/psychrometers) can be used to measure humidity. barometers are used to measure atmospheric pressure, while anemometers are used to measure wind speed. so the 2nd and 4th choices should be the correct answers.
