Answer:
We know that sin(x) = cos(90°-x). In that sense, we know that:
sin(25°) = cos(90°-25°) = cos(65°)
If you put both values in a calculator, we get that:
sin(25°) = 0.4226
cos(65°) = 0.4226
Therefore: Sin 25° = Cos 65°
Sea floor spreading adds more crust to the ocean floor and at the same time older strips of rock move outward from either side of the ridge.
The main vent is the main outlet for the magma to escape. Secondary vents are smaller outlets through which magma escapes. The crater is created after an eruption blows the top off the volcano
