"Why Do We Study the Sun?" How does the Sun help to protect life on Earth?
Answer:
We study about the sun because
The sun is a normal star. It is much closer to us than any other star, and by studying the sun, we can therefore learn more about other stars. The better we understand other stars, the more we know about the Milky Way. From there we know more about other galaxies and in the end we learn more about the universe.
Explanation:
How does the Sun help to protect life on Earth?
It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
State of high development of some countries is a cause of the under development of others. Discuss
Answer: exploitation
Explanation: points you can write about :
unfair trade - cash crops. poorer countries trade raw materials, it gets manufactured and sold back at a higher price
former colonies
Frank's dependency theory, the core exploits the periphery
you could also argue that the statement isn't true, geographical location can impact development. e.g. mountains and being landlocked makes it hard to trade.
climate can impact crops, regular extreme weather events make it hard to develop.
hope this helped!
A three-story building had its lightweight roof uplifted. Hint: low-rise three-story, non-residential, roof uplifted completely, but no damage to walls. a. Damage Indicator Number:_________b. Degree of Damage:_________ c. Expected Wind Speed:_________ d. EF-scale Rating: _______
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
