What if the Earth Were Hollow

The video explores the concept of digging through Earth, considering the Coriolis effect and the challenges of such a journey. It discusses the hypothetical scenario of a pole-to-pole tunnel, the gravitational forces involved, and the reversal of these forces as one travels through Earth's core. The video also examines the challenges of deep digging, such as heat, and the implications of a hollow Earth, including the loss of a magnetic field and increased solar radiation exposure.

What is the Coriolis effect responsible for in the context of Earth's rotation?

• Making hurricanes spin counterclockwise in the northern hemisphere

• Creating magnetic fields

• Causing earthquakes

• Increasing the speed of falling objects

If a tunnel were dug from pole to pole, what would be the main force affecting a person falling through it?

• Magnetic force

• Gravitational pull

• Friction

• Air resistance

Why did the Cola super deep borehole project in Russia stop?

• Excessive heat

• Political reasons

• Earthquakes

• Lack of funding

What would happen to Earth's magnetic field if it were hollow but weighed the same?

• It would remain unchanged

• It would become stronger

• It would reverse polarity

• It would disappear

In a hollow Earth scenario, what would happen to gravity inside the shell?

• It would fluctuate

• It would cancel out

• It would decrease

• It would increase
