ANSWER:
The cities of San Francisco and Los Angeles will get close together over time.
Step-by-step explanation:
- San Francisco is located on the North America Plate which is moving south-east. Los Angeles is on the 'Pacific Plate' which is moving north-west.
- Los Angeles lies '340 miles south' of San Francisco at present. The movement of these two tectonic plates will lead Los Angeles to move to the north of 'San Francisco'.
- This will take a lot of time; almost 16 million years because the 'tectonic plates' move at a 'very slow pace'.
