Let’s go step by step to fill in the blanks correctly.

First paragraph:
> A tornado is a violent rotating column of air that extends from a thunderstorm to the ground. These violent rotating columns of air can have wind speeds that reach up to 300 miles per hour. So how does a tornado develop? First, you need an air mass with warm moist air. The cold air must be above the warm moist air. When these two air masses meet, they create instability in the atmosphere. The cold air pushes the warm moist air into the atmosphere. As thunderheads develop, strong winds often blow horizontally above the front.
✔ Why?
- Tornadoes are defined as *rotating* columns.
- Wind speeds can reach up to 300 mph (this is standard knowledge for strong tornadoes).
- You need warm, moist air near the ground and cold air above — this setup creates instability.
- “Instability” is the key term when warm air rises under cold air.
- Winds above fronts often blow horizontally before tilting upward.
---
Second paragraph:
> The power of these winds along with drier wind closer to the ground, can make the rising air in a thunderhead start to rotate. If the wind is stronger with height, it tends to create a tilting effect to the atmosphere. This difference in wind direction and speed is called wind shear.
✔ Why?
- Rising air starts to rotate due to wind differences → “to rotate”.
- Stronger wind at higher altitudes causes rotation → “stronger”.
- This creates a “tilting” effect — turning horizontal spin into vertical.
- The technical term for changing wind speed/direction with height is “wind shear”.
---
Third paragraph:
> At first the rotating winds spin around a horizontal axis parallel to the ground. However, as the warm air continues to rise, the updraft becomes strong enough to lift the rotating air into a vertical spin, roughly perpendicular to the ground. If the rising air in a thunderhead begins to rotate, the column of spinning winds is called a tornado.
✔ Why?
- Initially, rotation is horizontal (like a rolling pin on the ground).
- Updraft lifts it to become vertical → perpendicular to ground.
- Once it touches ground and rotates vertically, we call it a tornado → “called”.

Final Answer:
A tornado is a violent rotating column of air that extends from a thunderstorm to the ground. These violent rotating columns of air can have wind speeds that reach up to 300 miles per hour. So how does a tornado develop? First, you need an air mass with warm moist air. The cold air must be above the warm moist air.
