Answer:
B. Convection.
Explanation:
Convection is an energy transfer process which typically involves the transfer of heat as a result of the movement of mass. Convection is generally considered to be a more effective and efficient means of heat transport in the Earth when compared to conduction. The movement of tectonic plates is caused by the convection current because the heat gains pressure underneath the crust.
Hence, the type of energy transfer which is responsible for the movement of magma in Earth's interior is convection.
Additionally, subduction zone is a zone which represents the collision between the two (2) tectonic plates of planet earth. Subduction zone occurs in countries such as Japan, Canada, Indonesia, Russia, Alaska, and around the Pacific Ocean.
Generally, subduction zones are responsible for high intensity earthquakes, volcanoes and tsunamis around the world.
None of above/D (but I'm not very sure)
Answer;
= 0.244 seconds
Explanation;
500 rpm is equivalent to; 1500 × 2π radians per minute
= 9424.8 rad/minute
To get revolutions per second we divide by 60
= 9424.8/60
= 157.08 radians per second.
Then we divide by 64.3 rad/s^2 to get time;
= 157.08/64.3
= 0.244 seconds.
Answer:
re believed to influence the Earth's magnetic field. ... As heat is transferred outward toward the mantle, the net trend is for the inner boundary of the liquid region to freeze, causing the solid inner core to grow
Explanation:
(a) Determine the circumference of the Earth through the equation,
C = 2πr
Substituting the known values,
C = 2π(1.50 x 10¹¹ m)
C = 9.424 x 10¹¹ m
Then, divide the answer by time which is given to a year which is equal to 31536000 s.
orbital speed = (9.424 x 10¹¹ m)/31536000 s
orbital speed = 29883.307 m/s
Hence, the orbital speed of the Earth is ~29883.307 m/s.
(b) The mass of the sun is ~1.9891 x 10³⁰ kg.
