Earth’s inner core growing lopsided - but will not cause tilting

The video discusses the faster growth of iron crystals beneath Indonesia compared to Brazil due to cooling rates. It explains how Earth's shape is maintained by spinning and gravity, and how seismic waves reveal core disparities. The study suggests that heat loss in the core affects Earth's magnetic field, which has weakened over the past two centuries. The potential future solidification of the core could leave Earth without its magnetic protection.

What causes the faster growth of Earth's east side beneath Indonesia compared to the west beneath Brazil?

• Faster cooling rates in the east

• More tectonic activity in the west

• Higher temperatures in the east

• Greater seismic activity in the west

How is Earth's spherical shape maintained?

• By the distribution of tectonic plates

• Through constant spinning and gravity

• Due to the presence of iron crystals

• By the magnetic field

What is a key factor in the disparity of seismic wave travel speeds through Earth's core?

• The presence of iron crystals

• Indonesia's mix of islands and sea floor

• The Earth's magnetic field

• The melting point of iron

What drives the flow of liquid iron in Earth's outer core?

• The presence of tectonic plates

• The gravitational pull of the moon

• Heat loss in Earth's inner core

• The Earth's rotation

What could be a consequence of the entire core becoming solid in the future?

• More frequent earthquakes

• Loss of Earth's protective magnetic field

• A stronger magnetic field

• Increased tectonic activity
