D. Ice has the power to sculpt the landscape.
A globe is smaller than a wall map (generally), so the pictures would be smaller and have less bias. The bias I am talking about in regards to the map would be like this: say a geographer creates a map, and he/she makes enlarges a certain country or makes a country smaller than it actually geographically is. For example, last year, in our class, we had this map that made the continent of Africa, for instance, look ridiculously huge compared to the other countries. Africa may or may not actually be that big, so it is likely that the creator of the map used a bit of bias to determine which countries/continents should be bigger, etc. With a globe, you do not have that bias (or less of it), because the countries and continents need to be smaller to fit on the globe. It can be said that this way, the representation of the countries and continents is a bit more accurate than the maps that are not drawn to scale. I would say that satellite images can be less accurate than globes as well because although it is a more accurate diagram than a map would be, it may still have parts enlarged to it/bias depending from which angle or location the image was taken from. The globe is, in my mind, more geographically accurate than a map or satellite image, and also, with a globe, you can spin it around, which can show the earth spinning on its axis and it is more tactile than maps or images, so you can use it in more different ways than you could a map or image.
Answer:
Deep ocean exploration is all about investigating its geology i.e physical and chemical along with biological conditions on the ocean floor where sunlight cannot reach. There has been an interest in the deep ocean due to scientific communities and for industrial purpose. Exploration is carried by submarine and remotely operated vehicles at about 300m to 1000m. Analysis of ocean floor had found a huge concentration of mineral deposits such as manganese, copper, cobalt, gold, zinc etc.
The mining is carried out by using hydraulic pumping or bucket type excavator and are processed on ground industries. Deep-ocean mining has not been able to reach its full potential due to the high cost of operating and environmental damage.
