Step by Step Written Solution
In this problem, we need to match descriptions of how lightning forms with the correct completing phrases. Let's look at the science behind each statement.
Matching: Weather & Electricity
The first phrase says, where positive charges have clustered due to the pull of the thunderhead. Looking at our options, this describes a location on the ground.
In nature, opposites attract. If there's a strong negative charge in the cloud above, positive charges on the ground will move toward it. We are looking for a completion for a high point on the ground.
For the second statement, when a stream of negative charges pours down towards a high point, it happens to meet the electrons or positive stream coming up. The option to meet the electrons fits perfectly here.
Matching: Weather & Electricity
Statement 1: Ground positive cluster
Statement 2: *When this happens, a stream of negative charges pours down towards a high point...*
