How does a battery create electric current in the circuit?

• electrons move back and forth quickly changing direction all the time

• electrons are attracted by negative and repelled by the positive terminal

What sentence below describes Hampton's climate?

Hampton, Virginia is a city founded in 1610, it is a city of first scientists. With NASA as a

close neighbor, the James River, Hampton Roads, and the Chesapeake Bay Watershed;

Hampton is a prime area to become a true scientist. The weather also provides

opportunities to evolve with science. During the month of October, science comes alive

when Hampton is cooler in the mornings, but warms up in the evenings.
