Igneous rocks form from the cooling and solidification of lava or magma.
I'm not a big fan of this question, but I think the "desired" answer is grain-size (from very large to microcrystalline) and interlocking texture.
(It could be tendentiously argued that tuff (also called tufa) and possibly other pyroclastic rocks, which form from volcanic ejecta, lack an interlocking texture because they are more like sediments that are welded together. I say this is tendentious because such rocks are about as much sedimentary as they are igneous, and are not typical igneous rocks if they are igneous rocks at all.)
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:
Pretty sure the answer is Panama Canal
Explanation:
We share this as 2 countries and it makes life easier for both sides. Also, the Gulf of Mexico is a shoreline.
