The following figure is a schematic diagram of seabed topography in some parts of the North Pacific Ocean. Look at the picture and answer the following questions. (10) (1) According to the provisions of the United Nations Convention on the Law of the Sea, ①

(1) High seas? Polymetallic nodules (or manganese nodules, ferromanganese nodules)? marine space resources

(2)④? high latitude

(3) a? six

(4) Trench? The ocean plate collided with the continental plate and the ocean plate swooped down.

This topic comprehensively examines students' ability to remember, master and understand knowledge such as the ocean.

(1)① According to the latitude and longitude range, it can be seen that the sea area has exceeded the territorial sea. There are a wide range of deep-sea manganese nodules in the Pacific Ocean, and the marine space resources are mainly used for submarine tunnel construction and maritime navigation.

(2) ① ② ④ The middle ④ latitude is relatively high. When the latitudes are similar, the influence of ocean currents is mainly considered, and when the latitudes are quite different, the latitude difference of solar radiation is mainly considered.

(3) In winter, rescue boats are vulnerable to easterly winds near the polar regions and low-temperature sea ice in high latitudes.

(4) (4) Located at the boundary of the plate boundary, the subduction of the ocean plate is easy to form a deep trench in the ocean.
