Tornado interactive worksheet - Free Printable

Let's solve this step-by-step.

I. Label the Diagram

We are given a diagram of a tornado and a list of terms to use:

Terms:
- eye of the storm
- upward current
- warm air
- cold air
- rain
- ground level

Now, let’s analyze the diagram:

1. Top left arrow pointing to the dark cloud: This is the rain, as it’s shown falling from the cloud.
2. Middle left arrow pointing to the area between the cloud and funnel: This is the upward current — air rising into the storm.
3. Bottom left arrow pointing to the surface (ground): This is ground level.
4. Right side, top arrow pointing to the center of the cloud: This is the eye of the storm — the calm center of the rotating system.
5. Right side, middle arrow pointing to the descending air: This is cold air — cooler air sinking from above.
6. Right side, bottom arrow pointing to the base of the funnel touching the ground: This is the warm air — rising moist air that fuels the tornado.

So, labeling the blanks in order from top to bottom on the left and right sides:

- Top left box: Rain
- Middle left box: Upward current
- Bottom left box: Ground level
- Top right box: Eye of the storm
- Middle right box: Cold air
- Bottom right box: Warm air

✔ Final Labels:
- Top left → Rain
- Middle left → Upward current
- Bottom left → Ground level
- Top right → Eye of the storm
- Middle right → Cold air
- Bottom right → Warm air

II. Fill in the Blanks

We are given these words to choose from:
- column
- upwards
- thunderstorm
- cold & dry air
- warm & moist air

Sentence:
> A tornado is a violent and rotating _________ of air between a ___________ and the ground. Tornadoes occur when ______________ blows over ____________. The warm air spins ____________ and forms a tornado.

Let’s go through each blank:

1. First blank: "rotating _________ of air" → This describes the structure of a tornado. The correct term is column.
→ "rotating column of air"

2. Second blank: "between a ___________ and the ground" → Tornadoes connect the sky to the ground, specifically from a thunderstorm.
→ "thunderstorm"

3. Third blank: "when ______________ blows over..." → Tornadoes form when warm & moist air rises and interacts with colder air. So, warm & moist air is the correct choice here.
→ "warm & moist air"

4. Fourth blank: "...blows over ____________." → The warm air blows over cold & dry air, creating instability.
→ "cold & dry air"

5. Fifth blank: "spins ____________" → The warm air spins upwards due to updrafts.
→ "upwards"

✔ Final sentence:
> A tornado is a violent and rotating column of air between a thunderstorm and the ground. Tornadoes occur when warm & moist air blows over cold & dry air. The warm air spins upwards and forms a tornado.

✔ Final Answers:

#### I. Diagram Labels:
- Top left: Rain
- Middle left: Upward current
- Bottom left: Ground level
- Top right: Eye of the storm
- Middle right: Cold air
- Bottom right: Warm air

#### II. Fill in the Blanks:
> A tornado is a violent and rotating column of air between a thunderstorm and the ground. Tornadoes occur when warm & moist air blows over cold & dry air. The warm air spins upwards and forms a tornado.

This completes the worksheet accurately and clearly!
