Paragraph: (Science-textbook/science-g4-14.txt)
Sent 1: You may wonder if there are other examples of static discharge.
Sent 2: The answer is yes.
Sent 3: Lightning is a form of static discharge.
Sent 4: It is much more dramatic than what happens between you and the door knocker, but it is the same principle.
Sent 5: You can see how it occurs in the following diagram and animation.
Sent 6: You have no doubt seen lightning in a rainstorm.
Sent 7: What does lighting have to do with static electricity?
Sent 8: As it turns out, everything!
Sent 9: During a rainstorm, clouds develop regions of different charges.
Sent 10: This happens due to the movement of air molecules, water drops, and ice particles.
Sent 11: The negative charges are concentrated at the base of the clouds.
Sent 12: The positive charges are concentrated at the top.
Sent 13: The negative charges repel electrons on the ground below.
Sent 14: The ground then becomes positively charged.
Sent 15: Over time the differences increase.
Sent 16: Eventually the electrons are discharged.
Sent 17: This is what we see as lightning.
Sent 18: You can watch an awesome slow-motion lightning strike below.

Question: What happens to electrons to make them turn into lightning? (false/0)

The negative charges repel electrons on the ground below
Electrons gets discharged
Electron becomes neutrally charged
Electrons repel negative charge on ground below
They discharge
Eventually the electrons are discharged
Slow-motion
Electrons change their properties

Question: What are we seeing when we see lightning? (true/1)

Discharge of electrons is what we see as lightining
Protons getting discharged from sky
We see positive charge getting discharged
Electrons getting discharged from clouds
The discharge of electrons

Question: Is lightning a form of static discharge? (true/4)

No
Yes
Agree
Disagree

Question: What are two examples of static discharge? (true/5)

Question: How do clouds develop different regions of charges? (true/6)

Due to dynamic discharge property of lightning
Through the movement of molecules, water drops, and ice particles
Because of motion present in air molecules, water drops, and ice particles
Because of movement of air molecules, water drops, and ice particles
Because positive charges are concentrated at the base of the clouds

Question: What does lightning have to do with static electricity? (false/7)

Lightning is a form of dynamic energy
Lightning is a form of static energy
Lightning is an example of static energy
As it turns out, everything
Everything!
Air molecules
Lightning and static energy are poles apart

Question: How is the top of a cloud different from the base of the cloud during a rainstorm? (true/8)

The positive charges are concentrated at the top
Top of cloud is neutral in charge
Bottom of cloud has dormant charge
He negative charges repel electrons on the ground below
Top and bottom clouds have opposite charges
Top and bottom clouds are oppositely charged
Negative charges are concentrated at the cloud base and positive charges are concentrated at the top

Question: How does ground become positively charged? (false/9)

The negative charges which are concentrated at the base of the clouds repel electrons on the ground below
The negative charges from the cloud base repel electrons on the ground below
The positive charges which are concentrated at the base of the clouds attract electrons on the ground below
Positive charges at the base of the clouds.attract electrons on the ground below
Negative charges at the base of the clouds.repel electrons on the ground below

Question: How can different regions of clouds have different charges? (true/10)

Due to dynamic discharge property of lightning
Because of motion present in air molecules, water drops, and ice particles
Because of movement of air molecules, water drops, and ice particles
It is due to the movement of air molecules, water drops, and ice particles
Because positive charges are concentrated at the base of the clouds
