Answer:
Options (A), (B), (C), and (D)
Explanation:
The volcanic activity refers to the eruption of magma at the surface of the ocean floor and continental land areas, forming volcanoes.
Some of the tectonic settings that are associated with volcanic activity are as follows-
- Mantle plumes- These are the large uprising bodies of magma that are generated due to the formation of convection current in the mantle. These are localized body and are located away from the tectonic boundaries. For example, Hawaii is formed as the plates moved over the mantle plumes.
- Continental rifts- This refers to the eruption of magma at the surface of the continents, due to the divergent motion of two continental plates. It results in the formation of a rift, rift valley and then later forms an ocean.
- Island arcs- These are formed due to the collision of two oceanic plates, where the volcanoes are formed on the lighter oceanic plate due to the rising up of magma.
- Continental arcs- These are formed due to the collision between an oceanic and a continental plate, where the volcanoes are formed due to the uprising of magma in the lighter continental plates.
Answer:
Russia has built the Trans-Siberian Railroad to overcome the Friction of Space.
Explanation:
Russia is the largest country in the world, and on top of it, its territory is stretched by longitude which creates a situation where from the easternmost to westernmost point the distance is incredibly big. As both the eastern and western coasts are strategically very important for Russia, it is crucial that they are connected with infrastructure that will enable relatively fast and cheap transportation and traveling.
The solution came in the form of the Trans-Siberian Railroad. This is the longest railroad in the world, starting from Saint Petersburg, diverging into two lines, one going to Tyumen but before that at Yekaterinburg turning to merge with the other line at Chelyabinsk, continuing to Chita where it diverges again with one line going through Khabarovsk to Vladivostok while the other moving slightly through Mongolia, Harbin in China, and ending in Vladivostok.
