The boundary of the north american plate and the african plate in the atlantic ocean is an example of which type of plate boundary?

Divergent plate boundary

Explanation:

A divergent plate boundary can be simply defined as a contrasting plate boundary where two distinct lithospheric plate move away from one another. This results in the creation of new crust and these new materials are added along the mid oceanic ridge. This type of plate boundary is commonly observed in different locations on earth.

For example, the North American plate shares a divergent plate boundary with the Eurasian and the African plate, in the Atlantic ocean.

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
