There are two dominant theories:
The inside-out model proposes that the Earth formed with trace amounts of water structurally bonded to the minerals in the mantle. This water makes its way to the Earth’s surface through volcanic processes.
The outside-in model proposes that the Earth formed without water, which came with other volatiles from the meteorites or comets that bombarded the young planet. This water was probably mixed into the upper layers of the Earth and was later brought to the surface through volcanism.
Answer:
a). 2
b). Moderate
c). 73-112 mph
d). F1
Explanation:
A Fujita scale is a scale that is used to determine the rating for the tornado intensities. It is used to measure the intensity of the tornado and provides a rating based on the damages made by the tornado on the human built structures and other vegetations.
The rating is based on the wind sped and the damages caused by the winds. When the damages caused by a tornado is surveyed, it is compared to the lists of Damage Indicators and the Degree of Damage which helps to estimate the range of the speeds of the tornado and an EF scale rating is provided accordingly.
In the context, It is given that the lightweight roof of a three storied building was uplifted. It was a non residential low rise three story building whose roof was uplifted completely but there was no damages made to the walls of the building.
So according to the EF scale, it provided a rating of :
Damage Indicator Number : 2
Degree of Damage : Moderate
Expected Wind Speed : 73-112 miles per hour
EF-scale Rating : F1
