The plate labeled with A is the South American plate, the one labeled with B is the African plate, and the one labeled with C is the Australian plate.
Explanation:
The three plates that are marked on this map are the South American, African, and Australian (Indo-Australian) plates. All of these three plates have a core of continental crust which is surrounded by oceanic crust. The three continents on these plates are South America, Africa, and Australia (plus the subcontinent of India). Despite the three continents being separated by oceans between them at present, it was not like that throughout the past.
- In the distant past these three continents were merged, being part of Gondwanaland, accompanied by India and Antarctica as well.
- Divergent boundaries arose between them though, so they started moving apart and gradually formed new continents.
- As it stands, there is no evidence that these plates will merge again in the next few million years, as the South American plate moves west, the African is actually splitting into two plates, and the Australian is moving toward northeast.

10,15,20,25
Explanation:
union mean the combination of all
Answer:
Water
Explanation:
Acetone has a higher vapour pressure than water because acetone molecules only experience dispersion forces and diploe interactions as the dominant intermolecular forces.
In addition to these mentioned, water molecules are held together by strong hydrogen bonds. Therefore, water has a much lower vapour pressure than acetone and requires greater energy to break these hydrogen bonds and convert the liquid water to gaseous state.
Answer:
Explanation:
Abyssal plain : very level area of the deep-ocean floor typically lying at the foot of the continental rise G
Guyot: A submerged flat-topped seamount H
Deep-ocean basin: portion of the seafloor between the continental margin and oceanic ridge; comprises 30 percent of Earth's surface C
Continental Volcanic Arc: Mountains are formed in part by igneous activity associated with the subduction of oceanic lithosphere beneath a continent A
Deep-Ocean Trench: Long, relatively narrow crease in the seafloor that forms the deepest parts of the ocean. D
Oceanic Plateau: extensive region of the ocean floor with thick accumulation of pillow basalts and other mafic rock E
Seamounts: An isolated volcanic peak that rises above the deep-ocean floor
Volcanic island arc: A chain of volcanic islands generally located a few hundred kilometers from a tench where active subduction of one oceanic slab beneath another is occuring; some trenches run parallel to an arc shapes row of active volcanoes
