Earth’s strange blobs could be huge pieces of alien planet

The video discusses the impact of a planet-sized body called Thea on Earth around 4.5 billion years ago. Scientists theorize that Thea's remains formed two large, mysterious blobs of rock deep in Earth's mantle. These blobs, located beneath West Africa and the Pacific Ocean, are dense and chemically distinct from surrounding mantle rock. Seismologists have studied these formations for decades, and new isotopic evidence suggests they may be remnants of Thea. The study is currently under review.

What event is believed to have led to the formation of two large blobs in Earth's mantle?

• A massive earthquake

• A volcanic eruption

• The cooling of Earth's core

• The collision with a planet-sized body called Thea

Where are the two mysterious blobs located within Earth's mantle?

• Under the Sahara Desert and the Amazon Rainforest

• Below the Arctic and Antarctic regions

• Beneath West Africa and the Pacific Ocean

• Under the Atlantic Ocean and the Himalayas

What characteristic of seismic waves suggests that the blobs are different from surrounding mantle rock?

• They disappear

• They slow down

• They change direction

• They speed up

What recent evidence supports the theory that the blobs are remnants of Thea?

• Historical documents

• Fossil records

• Satellite imagery

• Isotopic evidence and modeling

What is the current status of the study regarding the blobs' origin?

• It is being ignored

• It has been rejected

• It is under review

• It has been published
