I'm not 100% sure, but I believe it is because the Amazon River flows through Brazil. This is a great opportunity and source of hydroelectric power that can be taken advantage of instead of wasting money on fossil fuels or other power sources.
Answer:
(C) The reaction between dissolved carbon dioxide and carbonate ions to form bicarbonate significantly enhances the ocean’s capacity to store carbons.
Explanation:
ocean consumes mainly carbon dioxide from atmosphere. This is done by the process of photosynthesis performed by the plants like organisms in the sea known as phytoplankton. Through this process carbon dioxide dissolves in water further reacting with sea water creating carbonic acid. This carbonic acid leaves hydrogen ions which later combines with carbonate to form bicarbonate. The result of formation of bicarbonate increases the capacity of sea to store the carbon which doesn’t escape the ocean easily.
So option (c) will be correct answer
Answer:
Granite
Explanation:
Obsidian is an extrusive rock, as it is formed on the surface of the Earth from lava, which is magma that has emerged from underground. However, granite is intrusive since it is formed from magma that cools and solidifies within the crust of the planet.
