Answer:

(b) a descending convection current in the Earth's mantle.

Explanation:

We cannot see the deep interior of Earth, but we know from a variety of observations that it is in continuous motion. This is because the mantle convects. This fundamental planetary process has profoundly influenced the character and evolution of Earth.

Mantle convection is the main way heat from Earth's interior is transported to its surface, and this heat escapes principally through mid-ocean ridges. In fact, the connected mid-ocean ridge system is in essence a 80,000 km long volcano.

Heat in the mantle comes from the Earth's molten outer core, decay of radioactive elements and, in the upper mantle, friction from descending tectonic plates. The heat in the outer core results from residual energy from the Earth's formative events and the energy generated by decaying radioactive elements. This heat warms the base of the mantle to an estimated 7,230°F. At the mantle-crust boundary. the mantle's temperature is an estimated 392°F.

Alinara [238K]

Answer:

Sudans many years of civil war have resulted from conflicts between "Muslim Arabs, and Christian and animist Africans. "

Explanation:

Religion is the essential effect in Sudan’s civil war. The North, with most of Sudan's land and inhabitants, is Muslim and Arabic-speaking, and their religion and language are both important for their individuality. On the other hand, the South´s individuality is indigenously African, with Christian and Western influences. Sudan's first civil war was fought between the Arab-led Khartoum government in the north and rebels in the largely Christian and animist south. Southern rebels were fighting for regional autonomy and representation in the government. A peace agreement was signed in 1972 that granted semi-autonomy to the south.
