Earth's interior taking in more seawater than previous thought, study finds

Research around the Mariana Trench shows that the Earth is absorbing more water than previously estimated. Scientists used seismographs to study the area, revealing that the Pacific plate is sliding under the Mariana plate, allowing seawater to seep into the Earth's crust. This water may transform into hydrous minerals due to high pressure and temperature, eventually sinking deeper into the mantle.

What did the researchers discover about the Earth's water absorption near the Mariana Trench?

• It is absorbing less water than expected.

• It is absorbing the same amount of water as expected.

• It is not absorbing any water.

• It is absorbing 4.3 times more water than previously thought.

How did researchers collect data on the seismic activity around the Mariana Trench?

• By using drones.

• By deploying seismographs both underwater and on land.

• By using satellites.

• By collecting water samples.

What happens when the Pacific plate slides under the Mariana plate?

• It creates new islands.

• It allows seawater to seep into the Earth's crust.

• It causes volcanic eruptions.

• It stops all seismic activity.

What transformation occurs to seawater under high temperature and pressure in the Earth's crust?

• It forms hydrous minerals.

• It becomes a gas.

• It turns into ice.

• It evaporates.

What is the fate of the hydrous minerals formed in the Earth's crust?

• They are incorporated into the lower plate and sink into the mantle.

• They dissolve in seawater.

• They rise to the surface.

• They remain in the crust.
