A. map
Explanation:
A map is a projection that is used to represent real life phenomenon on a two dimensional surface.
A project of the Gulf of Mexico showing currents and water depth would be a map.
Maps are very good descriptive resources for delineating surface and even subsurface features.
Weather maps usually cover current patterns in the world.
Water depth in places can also be presented using water depth maps too.

The other type of a region that characterises low precipitation would also be a semiarid or a steppe. In addition, this specific kind of region usually consists of little to no vegetation. The area could only grow grasses and no trees can be seen in this region because of its barren descriptions.
Answer: D. The economy was struggling in much of 2009.
Explanation:
In 2009, the ownership of mp3 players seemed to dip from April to September and only recovered afterwards.
Laptop computer ownership may not have decreased but stopped growing and remained the same in the same period. Desktop computer decreased in ownership and even Cellphone ownership decreased as well.
This means that all four gadgets were affected in 2009 in a negative manner which means that the economy struggled in that time period in 2009.
Answer:
Nanotechnology helps to improve viscous fingering and the nano-particles can transmit through nanopores of sandstone which helps to increase the recovery by decreasing the surface tension between oil and water. The pore spaces are very fine so water molecules cannot penetrate through all of them in order to push the oil. This is why the nano-particles such as iron (Fe) and Silicon (Si) are used with distilled water. These particles can easily move through the interconnected pores and thereby pushes the oil to move out of it. It is a widely accepted concept in Enhanced Oil Recovery (EOR).
C. continental drift
(If the continent drifted apart, similar fossils were previously proximal would now be great distances apart)
