Answer:
DC equals EC times AC all over BC
Explanation:
The parallel lines divide the segments proportionally, so you have ...
DC/AC = EC/BC
Multiplying by AC gives ...
DC = (EC·AC)/BC . . . . . . matches the 1st Choice
Answer:
D

The given question is incomplete as the options are missing. The options related to the given question are as follows-
(A) Crust is formed
(B) Mountains are formed
(C) Seafloor spreading occurs
(D) Crust becomes molten rock
(E) Denser plates slide under lighter plates
Answer:
Options (C), (D) and (E)
Explanation:
Trenches are usually defined as the V-shaped depressions that are formed in the convergent plate boundary, where the denser plate sinks below the lighter one.
These are usually extended up to a great depth, such as the the Mariana trench which is about 11 km deep. These trenches marks the boundary between the two plates.
In a convergent plate boundary, with a distinct deep oceanic trenches, the seafloor spreading takes places extensively, and the downgoing crust undergoes partial melting and becomes hot molten rocks that eventually mixes up with the magma.
Thus, the correct answers are options (C), (D) and (E).
Tropical cyclones require warm surface waters at least 80° F or 27° C. During the late summer months, the sea surface temperatures reach their highest levels and provide tropical cyclones with the energy they need to develop into major storms.
The answer is A. Highland climate occurs mainly in the highlands where the lands are tall, in meters above the sea level then most of the most surrounding lands. These regions are characterized by high precipitation and cool temperatures because of the lands force warm air current up to the cooler atmosphere. The warm air current cool and their water content condenses and precipitates as rain.
