Convection currents occur in the MANTLE. The mantle is the second layer of the earth after the crust. The mantle is approximately 2900 km thick. Convection currents are triggered or fueled by the heat from the Earth's core.
The part of the mantle closest to the core gets heated. It then becomes less dense than the layers above so it rises. When this rising plume interacts with the crust it cools and becomes more dense than the layers below and so it sinks and this circular motion continues to form convection currents.
Answer:
c=49 degrees
b=131 degrees
Explanation:
Angle c and the angle that measures 49 degrees are opposite angles. Opposite angles are equal to each other, so we can conclude that angle c is equal to 49 degrees.
c=49 degrees
Angle c and angle b are both sitting on a straight line, and a straight line has an angle measure of 180 degrees. To find angle b, we can subtract 49 from 180.
b=180-49
b=131 degrees
Therefore,
c=49 degrees
b=131 degrees
I hope this helps!
