Answer:
Canada, United States, Brazil, Argentina
Explanation:
The four largest countries by area in the Western Hemisphere are Canada, United States, Brazil, and Argentina. These countries are located in North and South America, with Canada and the United States being in North America, while Brazil and Argentina being in South America. All of these countries are in the top 10 largest countries in the world by area, with Canada being on the second place, the United States on third, Brazil fifth, and Argentina eight. One of the main reasons why these countries are so large is because they are countries of the New World, all being former colonies, where the populations where relatively small, but the European settlers managed to occupy very large areas. Once they gained independence, the boundaries were set in accordance to the colonial boundaries, so instead of having numerous smaller countries divided because of ethnicity, race, or culture, large multiracial, multiethnic, multicultural countries were established.
Answer:
Convergent boundaries are the faults where two plates converge, or collide, and can form the following;
NO) rifts form
YES) subduction occurs
YES) Island arcs form in the sea
NO) mid-ocean ridges mark locations
YES) volcanic mountains form on land
Answer: Two hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released.
Explanation:
All stars (including the Sun) at birth begin to fuse two hydrogen nuclei to form helium through nuclear fusion.
In this sense, nuclear fusion is the union of two light atoms, releasing energy in the process, which is the cause of the great luminosity of a star. Especifically, the hydrogen nuclei will begin to fuse, generating helium nuclei in the process and releasing huge amounts of energy.
To unerstand it better:
To shine, the stars transform their hydrogen into helium by means of nuclear fusion. When at half of its life a star is without hydrogen, the nucleus becomes entirely helium and the star declines, becoming colder and brighter due to the energy generated by the nuclear reactions, then the star begins to contract.
Nevertheless, if the star is bigger, this helium will be also consumed and the nucleus transformed in Carbon, then in Oxigen, and so on. Being the last transformation Iron until the star delivers all its energy.
Because if the axis wasn't tilted the sun wouldn't shine on the top of the earth.
