The correct answer is - C. hot spots in the mantle.
The Hawaiian Islands are a volcanic islands. They are lying above a hot spot. The hot spot volcanoes, unlike the other ones, are far away from the boundaries of the tectonic plates and they are emerging on places were there's hot spots. These hot spots manage to penetrate through the crust and get the magma from the mantle up to the surface and create volcanic islands in meantime.
Answer:
It made significantly better predictions of planetary positions in our sky
Explanation:
Of the following statements the one which was not a major advantage of Copernicus's Sun-centered model over the Ptolemaic model is that it made significantly better predictions of planetary positions in our sky. Both the model made similar predictions of planetary position in our sky. In fact the Ptolemaic model was even better than the Copernicus's heliocentric model when it came to positioning of planets.
The Hawaiian Islands are formed on a region of intra plate volcanic activity on the Pacific plate. This region is known as a hot spot. Scientists are not exactly sure what causes this but they do know that a plume of magma rises through the mantle and forces it's way through the crust to form submarine volcanoes and over time volcanic islands.
The magma that rises here originates from the mantle and not crustal melt and so forms basic or basaltic lava.
The country of Brazil & Bolivia are the pair which share a border.
The border in this context refers countries which shares a close or immediate boundary. For instance, the nation of U.S. and Canada shares a border.
Here, the pairs including "Belgium & Bulgaria", "Belize & Barbados" and "Belarus & Bangladesh" does not share a boundary.
Hence, the country of Brazil & Bolivia are the pair which share a border.
Therefore, the Option B is correct.
Missing options includes <em>"a. belgium & bulgaria b. brazil & bolivia c. belize & barbados d. belarus & bangladesh."</em>
