Answer:
1- Option (D)
2- FALSE
Explanation:
The seafloor spreading takes place because of the divergent plate motion. Alfred Wegener observed this motion of the seafloor and the continents but was not able to explain the main mechanism behind this until the new theory came into the picture. The divergent motion of seafloor and the motion of the continents were explained by the universally accepted theory known as the Plate tectonic theory. This theory was able to explain the mechanism behind this plate motion.
The study of the seafloor spreading provided some pieces of evidence that supported the continental drift theory. They gave a basic idea about how the oceanic plate gets subducted (consumed) at the convergent plate motion that undergoes partial melting at greater depth. As a result of which the magma rises up to the surface on the overriding plates.
The crust represents the outermost layer of the earth. They are of 2 types, namely the oceanic and the continental crust. These crusts when slide past one another in a transform plate boundary, it is neither created nor destroyed. It remains conserved.
Thus, the correct answers are given above and the second statement is false.
Answer:
Desertificación.
Explicación:
La quema de combustibles en industrias y vehículos produce gas dióxido de carbono en una gran cantidad que contamina el aire. Este gas de dióxido de carbono es un gas de efecto invernadero que se acumula en la atmósfera y bloquea la radiación solar que va al espacio después de la refección, lo que provoca un aumento de la temperatura de la tierra y una condición de sequía que conduce a la desertificación. Debido a esta desertificación, la vegetación se elimina por falta de agua suficiente.
Answer: The width of the original car = 96 inches.
Explanation:
Given: The similarity ratio of a replica car = 1:30
The width of the replica car = 3.2 inches.
By using the similarity ratio,
The width of the original car = 30 x (width of the replica car )
i.e. The width of the original car = 30 x 3.2 inches
i.e. The width of the original car = 96 inches
Hence, the width of the original car = 96 inches.
Answer:
Norway
Explanation:
Officially there are three countries that compose Scandinavia, Norway, Sweden, and Denmark. Occasionally, Finland, Iceland, Faeroe Islands, and Aaland Islands are included, but that is only for local usage.
Out of the three countries, the one that has the biggest elevation is Norway, with Sweden coming as second, and Denmark having the lowest elevation. Norway's average elevation is 460 m. Sweden's average elevation is 320 m. Denmark's average elevation is only 34 m, making it the fifth joint lowest country in the world.
Norway has the highest elevation out of the three because the around half of the country is dominated by mountains, while Sweden also has mountains, it is mostly dominated by lowlands, and Denmark is entirely very low, lacking a single mountain or even a higher hill on its territory.
