The correct option for the statement, “Glaciation during the Cenozoic resulted in”.

Answer to Problem 9RAT
The correct option for the statement, “Glaciation during the Cenozoic resulted in” is option (d).
Explanation of Solution
The Cenozoic era, known to be the age of mammals, was made up of two periods. They were tertiary and the quaternary. During the early age of the Cenozoic era, the final phase of Pangaea’s breakup started, which causes North America and Greenland to split away from Europe, and Antarctica split form Australia. Numerous collision took place due to the landmass collisions. During this period, the formation of huge ice glaciers took place from a large amount of water, causing the sea level to drop worldwide. This resulted in the formation of land bridge connections between the continents. Also, the surface of Earth was carved, as glaciers were formed.
Conclusion:
The correct option for the statement, “Glaciation during the Cenozoic resulted in” is option (d).

- Four capacitors are connected as shown in the figure below. (Let C = 12.0 µF.) A circuit consists of four capacitors. It begins at point a before the wire splits in two directions. On the upper split, there is a capacitor C followed by a 3.00 µF capacitor. On the lower split, there is a 6.00 µF capacitor. The two splits reconnect and are followed by a 20.0 µF capacitor, which is then followed by point b.
