Answer:
d) Principle of Conservation of Matter
Explanation:
Principle of Conservation of Matter -
According to the law of conservation of matter, matter is the substance which ac not be created and even it can not be destroyed , hence we need to have the same number of atoms before and after the reaction constant during a chemical change or process of chemical as were number of atoms and type of atoms present before the chemical change .
Hence , from the options , the correct answer is the Principle of Conservation of Matter .
It would have to be Brazil
Oceanic and continental plates are colliding.
Explanation:
On the image, we can see an oceanic plate on the left, and a continental plate on the right, moving toward each other and colliding. Because the two plates have different densities, thickness, and elevation, one of the subducts below the other, that being the oceanic plate. As the oceanic plate subducts below the continental plate, it gradually moves down in the mantle layer, getting melted, recycled, and maybe the same material be pushed toward the surface again.
On the plate boundary, convergent in this case, there is intense geological activity. Magma manages to rise through the cracks and gaps, and it forms volcanoes, creating a continental volcanic arc. Also, there are lot of earthquakes at such boundaries, as there is constant adjustment of the crust.
Such boundaries can be found between the:
- Pacific and North American plates
- Pacific and Eurasian plates
- Pacific and Australian plates
- Pacific and Philippine plates
- Nazca and South American plates
- Cocos and North American plate
