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
A limiting factor is something in a ecosystem that limits the growth of a species. In this case, cowbirds are limiting factors to wood thrushes because they lay eggs in the nests of wood thrushes, which is called "nest parasitism." A decrease in the carrying capacity—the number of living organisms that a region can support (without environmental degradation)—of wood thrushes could be caused by a decrease in the insect population size. The less insects, the less food. With less resources, the carrying capacity will decrease for wood thrushes. If the cowbird population were decreased, or the space or number of nesting sites were increased, the carrying capacity would increase, instead.
Answer: B
Answer:
Continental margin
Explanation:
The submerged outer edge of a continent is called the into two major provinces. The submerged outer edge of a continent is called the continental margin. The deep seafloor beyond the continental margin is properly called the ocean basin
