Why Did This Happen?
100

What caused Piccard to build a pressurized cabin?

His need to survive in the stratosphere where there is little oxygen.

100

What problem did the pressurized cabin solve?

It allowed humans to breathe and survive at high altitudes.

100

What came first: Trieste or cosmic rays study?

Studying cosmic rays.

100

What danger is common in both environments?

Extreme conditions unsafe for humans.

100

Why did Piccard need oxygen?

There is not enough oxygen in the stratosphere.

200

What happened as a result of releasing gas from the balloon?

The balloon became heavier and began to descend.

200

How did the Trieste solve ocean pressure?

It used a thick steel spherical cabin.

200

What happened after Piccard built the balloon?

He traveled to high altitudes.

200

How are the balloon and Trieste similar?

Both are pressurized to protect humans.

200

Why did the Trieste use thick steel?

To withstand deep ocean pressure.

300

Why did the Trieste continue descending after it stopped?

Gas was released to reduce buoyancy, allowing it to sink further.

300

What problem occurred when the Trieste stopped descending?

It hit a dense layer of water that prevented sinking.

300

What happened before reaching the ocean floor?

The window cracked and descent slowed.

300

How are the challenges different?

Low oxygen vs. high pressure.

300

Why didn’t they stay long at the bottom?

Surfacing at night was dangerous.

400

What effect did the cracking window have on the mission?

It increased danger, but the inner layer held so the mission continued.

400

What solution allowed the Trieste to return to the surface?

Releasing iron pellets made it rise.

400

What led to designing the Trieste?

Success with pressurized balloon cabins.

400

How did balloon ideas help the Trieste?

The pressurized cabin concept transferred.

400

Why release iron pellets?

To make the craft lighter and rise.

500

Which cause had the greatest impact on success? Explain.

Engineering design had the greatest impact because it allowed survival.

500

How did solving one problem create another?

Going deeper increased pressure risks and danger.

500

How did early events influence later exploration?

Balloon experiments led to deep-sea technology.

500

Why is Piccard’s work important across fields?

It connects atmospheric and ocean exploration.

500

Why were these inventions necessary?

Humans could not survive without them.
