Weather fronts investigation worksheet featuring diagrams and fill-in-the-blank questions about cold, warm, and occluded fronts.

Let’s solve this step by step.

We are given a paragraph with blanks and a word bank. We need to pick the right words from the word bank to fill in each blank so the sentences make sense based on what we know about weather fronts.

Here’s the word bank again:
above, change, masses, boundary, two, direction, period, cloudy, thunderstorms, cold, overtakes, temperature

Now let’s go sentence by sentence:

1. “Weather Fronts mark the ________ between two air masses.”
→ A front is where two air masses meet — that’s called a boundary.
✔ Fill in: boundary

2. “The air masses can have large ________ differences on either side of the front.”
→ Air masses differ mostly in how hot or cold they are → temperature
✔ Fill in: temperature

3. “When a weather front passes, there is often a ________ in wind ________ as well as changes in temperature.”
→ Wind changes its speed or direction → first blank: change, second blank: direction
✔ Fill in: change, then direction

4. “Cold Fronts occur when a colder air mass ________ a warmer air mass.”
→ Cold air pushes under warm air → it overtakes it
✔ Fill in: overtakes

5. “This can create a short ________ of heavy rain and strong ________.”
→ Short time = period; strong storms = thunderstorms
✔ Fill in: period, then thunderstorms

6. “Warm Fronts move slower than cold air ________.”
→ Comparing movement of fronts → cold air masses (plural)
✔ Fill in: masses

7. “A warm front will steadily rise ________ the cooler air and create gentle rain showers.”
→ Warm air rises over cold air → above
✔ Fill in: above

8. “An Occluded Front is formed when a ________ front catches and overtakes a warm front.”
→ Only one type left that makes sense here → cold front
✔ Fill in: cold

9. “A Stationary Front is the boundary between ________ air masses that are not moving.”
→ Two air masses stuck → two
✔ Fill in: two

10. “Clear skies or partly ________ skies may occur, with occasional light rain.”
→ Opposite of clear → cloudy
✔ Fill in: cloudy

Now let’s write out the full filled-in paragraph to check:

> Weather Fronts mark the boundary between two air masses. The air masses can have large temperature differences on either side of the front. When a weather front passes, there is often a change in wind direction as well as changes in temperature. Cold Fronts occur when a colder air mass overtakes a warmer air mass. This can create a short period of heavy rain and strong thunderstorms. Warm Fronts move slower than cold air masses. A warm front will steadily rise above the cooler air and create gentle rain showers. An Occluded Front is formed when a cold front catches and overtakes a warm front. A mix of rain and thunderstorms can occur as a result. A Stationary Front is the boundary between two air masses that are not moving. Clear skies or partly cloudy skies may occur, with occasional light rain.

Everything fits logically and matches science facts about weather fronts.

Final Answer:
boundary, temperature, change, direction, overtakes, period, thunderstorms, masses, above, cold, two, cloudy
