Explanation:
The Ring of Fire is the result of plate tectonics. Tectonic plates are huge slabs of the Earth’s crust, which fit together like pieces of a puzzle. The plates are not fixed but are constantly moving atop a layer of solid and molten rock called the mantle. Sometimes these plates collide, move apart, or slide next to each other which causes different outcomes.
Answer:
C. 2π cm
Explanation:
Measure of the length of arc(QR) = θ/360 × 2πr
Where,
θ = 60°
r = 6 cm
Plug in the values
Measure of the length of arc(QR) = 60/360 × 2 × π × 6
= 1/6 × 12 × π
= 2 × π
= 2π cm
Answer:
Secondary Succession
Explanation:
A secondary succession is usually defined as a type of ecological succession, where the new floras and faunas are resettled after the occurrence of flood, forest fire, earthquake or any other disaster that destroys the previously existed ecosystem.
This type of succession is possible to occur because the essential nutrients that are required for the survival of organisms occurring in a particular area are not completely destroyed.
The secondary succession takes place at a much faster rate compared to the primary succession.
Thus, in the given condition, the secondary succession will occur after the occurrence of a massive forest fire.
