<span>The flat lands are generally favorable for establishing agricultural practices, easy movement, and pleasant weather that contribute to the development of early societies. However, their major drawback is that they often lack sufficient trade avenues in later years, especially when water sources are scarce.</span>
The ocean floor remains largely uncharted due to the difficulty of accessibility without appropriate equipment.
Given that a basketball symbolizes the Earth's scale with a diameter of 23 cm, and considering that the Moon is approximately one-quarter the size of Earth—more accurately, 27%—the ball representing the Moon would have a diameter of 6 cm.
The approximate distance from Earth to the Moon is about 30 times the Earth's diameter, specifically 30.17 times, making the separation between the two balls, illustrating Earth and the Moon, around 694 cm.
The answer is C. San Francisco. Explanation: The San Andreas and Hayward faults, which are in proximity, generate significant tectonic activity in this area. Consequently, regions near these faults are more susceptible to tsunamis caused by the displacement of the ocean floor during earthquakes. Additionally, many islands and bays previously established are also periodically affected.
