Given that san francisco is located on the north american plate and los angeles is located on the pacific plate, are these two cities getting closer together or farther apart over time?

ANSWER:

The cities of San Francisco and Los Angeles will get close together over time.

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'.

Magma forms by partial melting of upper mantle and crust. partial melt means that only a fraction of the available material forms a melt, and that the remainder stays solid. the partial melt rises because of its lower density and ascends through he crust. this is so conclusive mean the answer would be magma igneous rocks or balistic magma.
