Answer 1

a. Positiveb. Downc. Upd. Lightning and thunder

Answer 2

## Step 1Thunderstorm clouds have a strong separation of charge, with a negative charge concentrated on the lower level of the clouds and a positive charge concentrated in the upper level of the clouds. This separation of charges creates an electric field.## Step 2The electric field created by the thunderstorm clouds induces a charge on the ground below. The negative charge on the lower level of the clouds induces a positive charge on the ground below.## Step 3The strong electric field can pull electrons off the air molecules, leaving positively charged ions. The electrons are pulled in the direction of the electric field, which is from the positive charge to the negative charge. In this case, the electrons travel downwards.## Step 4The positive ions, being attracted to the negative charge, travel upwards.## Step 5When the electrons and ions crash through the surrounding air with great energy, they produce a sudden increase in the temperature of the air. This rapid expansion of air produces a flash of light and a loud boom, which are known as lightning and thunder, respectively.
