Answer: photosphere; corona
Explanation: "The corona is the outer atmosphere of the sun. It is made of tenuous gases and is normally hiding in plain sight, overwhelmed by the bright light of the sun's photosphere. When the moon blocks the sun's face during a total solar eclipse, the corona is revealed as a pearly-white halo around the sun."
Researchers believed that First officer William Murdoch could’ve prevented the Titanic from sinking if he had acted early before the ship struck an iceberg.
<u>Explanation:</u>
Titanic was a liner (cruise) on board with 2,223 people from Southampton to New York. That hit on an iceberg while traveling in the sea and sunk in the North Atlantic Ocean. William Murdoch was the First Officer of the ship.
When the officer-in-charge warned him about the iceberg that has been spotted in the ship's path. And William waited for 30 seconds before changing the ship's direction.
Researchers had found that the iceberg was sighted at the distance of 1500 ft from the ship from the investigation of evidence. And the collision happened after 7 seconds of William's order to change the course.
If he didn't hesitate for that 30 seconds to give order then the ship could have saved as well as the people.
