What is the missing first step of the following process: - Ice inside the cloud bumps around and causes electrostatic charges - The cloud becomes a thundercloud - Electrostatic energy builds and forms a strong negative charge - Positive energy is attracted to the negative energy in the cloud - This positive energy gathers on the ground - The positive energy connects with the negative energy and forms lightning.
Ans: Ice forms inside a cloud

What is the missing first step of the following process: - The sediment breaks down into small particles - Wind or water picks up the sediment - The sediment travels along the same route as the wind or water - The sediment is deposited at new locations by the wind or water - The sediment is picked up again by new wind or water - The sediment travels further - The sediment is deposited again in a new place.
Ans: Sediment settles in a place due to gravity

What is the missing first step of the following process: - An electrical source, like a battery, produces an electrical current - The electrical current flows through the wire - The electrical current creates a magnetic field around the wire, magnetizing the metal - The magnetic field can be turned on and off by starting or stopping the electricity source -
Ans: A conducting metal, like copper, is wrapped around a piece of metal

What is the missing first step of the following process: - The trees die off - The dead material provides nutrients for more trees - The rising trees provide shelter - And more organisms begin to thrive - The ecosystem known as a forest is made.
Ans: Networks of trees start forming
