Can lightning strike the same place twice? Let's figure out what makes it happen in the first place.

Lighting is electricity, and electricity involves tiny particles. Some particles have a positive charge and some have a negative charge. The two opposite charges pull towards each other like the north and south ends of magnets.

Usually electric charges are fairly balanced but the turbulent winds of a storm caused electric charges to separates within the cloud.

Most lightning occurs within the cloud itself, but we're concerned about the lightning between clouds and the ground.

Lightning starts with negative charges moving from the clouds towards the ground. Scientists call it a stepped leader. Meanwhile an upward leader forms as positive charges move up from the ground usually from tall objects when a stepped leader and an upward leader meet, it makes a path for a much larger and brighter electric current to shoot up into the cloud. This is what we see in the sky as lightning. It happened so quickly that lightning seems to travel from the cloud to the ground.

When in fact the opposite is true. So, can lightning strike the same place twice? Absolutely.

For example Toronto CN Tower is struck by lightning around seventy five times each year. In fact in August 2011 the tower was shocked a record-breaking 52 times in 84 minutes. But don't worry the tower was built to withstand it. So it's a safe place to be if lightning strikes once twice or even 52 times.

2.   According to the text above, how was the electricity formed?

• Electricity was formed when negative and positive particles separated.

• When the lightning struck the tall objects.

• When the clouds collide.

• When the two opposite; positive and negative charges pull towards ach other.

3.   What is stepped leader on the text above?

• The negative charges from the clouds that moving to the ground.

• The positive charges from the clouds that strikes the tall objects.

• The clouds with electricity charges.

• The positive charges from the ground

4.   What happens when stepped leader and upward leader meet?

• The lightning hits the tall objects.

• The sky is sparking.

• The lightning travel from the cloud to the ground.

• The lightning is formed.

5. What is the main idea of last paragraph?

• The record of lightning strikes is 52 times in 84 minutes.

• The lightning can strike same place more than twice.

• Toronto CN Tower is safe place.

• The lightning never strikes Toronto CN Tower.

Let's look at the size of rain and how raindrops fall first.

We'll need the Sun when the Sun shines on water on the Earth's surface, the heat of the Sun warms the water turning it into an invisible gas called water vapour.

This process the changing of water into a gas is called evaporation because gases are lighter than liquids. Water vapor rises up into the sky and the further you move up and away from the Earth's surface the colder temperature gets, so in the sky the water vapor cools and changes back into tiny water droplets. This change is called condensation, and it is the opposite of evaporation.

Clouds are made up of tiny water droplets so when condensation occurs in the sky clouds form and grow. When water droplets bump into one another they stick together and grow in size they continue to grow until they are too heavy and fall as rain. They even grows they bump into one another on their journey from the cloud to the ground and every single raindrop that reaches the ground is made up of 1 million of the original tiny water droplets.

Raindrops fall on the ground surface or the Sun can shine on them and the whole process happens again. This is called the water cycle and keeps water moving from the ground to the sky providing the water needed for plants animals and people to survive.

6. What does vapour mean?

• Invisible gas of the Sun.

• Very tiny particle of water in the air.

• Gas particle in the air.

• The atmosphere.

8.   From the first paragraph we can conclude . . . . .

• The size of rain and how raindrops fall.

• The Sun produces the invisible gas.

• The Sun is the main factor of evaporation process.

• Water turns into gas because of Earth's surface.

9.   “ … the changing of water into a gas is called evaporation” (second paragraph)

The underlined word is the antonym of . . . . .

• solidification

• condensation

• desiccation

• vaporisation

10.   Why does water vapor change into water droplets in the  sky?

• Because the temperature isn't cold.

• Because the temperature is hot.

• Because the temperature is sizzling.

• Because the temperature is frosty.
