Answer: A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction. If we look at a system in homeostasis, a positive feedback loop moves a system further away from the target of equilibrium.
Answer:
Subduction zone and trench is formed
Explanation:
When two tectonic plates that are comprised of oceanic crust shares a convergent type of plate boundary, then the denser one subducts below the less dense one. Due to this convergent plate motion, a subduction zone is created, which is marked by the presence of an oceanic trench. As the subducting plate penetrates downward into the deeper zone, the process of partial melting takes place, which leads to the melting of the crust and eventually the constituent minerals are mixed with the magma. This magma again comes upward due to the force exerted by the convection current and thereby results in the formation of volcanoes in the over-riding plate.
Thus, the collision of two oceanic plates gives rise to the formation of a subduction zone and a trench.
The correct answer is Sea of Japan - answer b) is the correct one!
This sea borders Japan, South and North Koreas, China and Russia.
This sea is named after Japan in most languages, not only in English.
South to it is the East China Sea, which separates China from Taiwan.
I think the correct answer is B.
first 421÷ by pi
then the answer divided by 2
you divide the answer by 2 to find the radius because the radius is half the diameter
