Answer:
Both
Explanation:
The lithosphere is part of both the crust and the mantle.
It is the surface layer of the earth and also the most rigid layer. It is formed by the crust and the outermost part of the mantle. It is divided into two types: continental lithosphere and oceanic lithosphere.
The oceanic lithosphere has an approximate thickness of 50 - 100km, and the continental olithosphere of 40 - 200km.
 
        
             
        
        
        
D. a and c
Explanation:
To make a generator out of a bicycle, Devon will need two magnets and coil of wire. 
There is a close knit relationship between magnetism and electricity. Electricity can be generated by a wire changing flux in the presence of a magnetic field. 
- The magnets provide magnetic field for the process. 
- The coil of wire is placed in between the magnetic field generated by the magnets. 
- The bicycle pedal is connected to the set up to turn the wire in between the magnetic fields. 
- This way, electricity is produced.

<span>Halting advances in tech could be useful because the automation in many tasks has rendered the human touch obsolete in many lower-level positions. They can be done by machines without the need for stoppage time for breaks. Continuing technology can be useful because it can increase output and make it easier for people to get what they're wanting or needing without spending extravagant amounts of resources.</span>
