Farming is a common economic activity around two important rivers in South Asia, the INDUS and the GANGES
Explanation:
Ganges and Indus are two of the major rivers flowing in South Asia. They came into existence a long time ago. These rivers along with the Brahmaputra are known to be the backbone of South Asia in terms of culture and economy. The three rivers have contributed to the rise of the earliest civilizations in history.
Farming is the major economic activity in which these rivers have contributed and still contributing to the present as the soil present around them is very fertile and is ideal for various crops such as Wheat, Rice,Cotton,Sugarcane and Maize. The fertility of the soil is replenished when the rivers are flooded making it ready for next cultivation.
It would be B because long. Is up and down so A and D are incorrect and C is incorrect because there is a tiny portion that goes over 129

Answer: Volcano
Explanation:
The Great Rift Valley is the site of major geological activity that stretches from Mozambique to the Middle East. Scientists believe that Africa and the Arabian Peninsula were joined together before they were separated by a process called rifting.
As the Earths tectonic plates begin to tear apart in this region, molten magma emerge from the earth crust to fill the void resulting in a separation.
Geologist estimates that the phenomenon which resulted in the great rift valley started 25 million years ago and gave rise to the Red sea. It is believed that the Indian Ocean flooded into the rift to form the Red Sea.
The.magma that seeps upward to fill crustal voids in the rift valley emerge mainly via volcanoes. Hence, many active and semi-active volcanoes are scattered throughout the region referred to as the Great Rift Valley, including Mount Kenya and Mount Kilimanjaro.
