Where are the statements?
Answer:
24 degrees Fahrenheit.
Explanation:
The moist adiabatic rate is related to the variation of the temperature as the altitude increases.
A typical value is around 9ºF/km. This means that for each km, the temperature decreases 9ºF.
In this problem, we have that:
The temperature at the ground level is 60 degrees Fahrenheit.
So 4km above sea level it is going to be 60 - 4*9 = 24 degrees Fahrenheit.
<u>ANSWER:</u>
The Grand Canyon was formed by erosion.
<u>EXPLANATION:</u>
- The Grand Canyon is a 'Steep-sided canyon' carved by the 'Colorado river'.
- The Grand Canyon is '446 km long', '29 km wide' and has a depth of over 1857 meters.
- The recent studies have showed that the 'Colorado river' and its tributaries ran through the 'area' about '5 to 6' million years ago.
- Since that time, there is constant erosion by Colorado river. In this way the 'Grand Canyon' was formed by 'erosion'.
Between 1931 and 1940 a ton of soil blew out of the central and southern great. It was a period of severe dust storms that greatly damaged the ecology and agriculture during the 1930s.
Answer:
As per the question, option B i.e. 'As the star material gathers, its inward pressure grows' involves a cause('the material gathers') underlined that leads to the effect 'growing of inward pressure.' This sentence reflects a cause-and-effect structure as it states an important fact about the beginnings of the Blackhole by displaying the cause or reason i.e. 'gathering of star material' which resulted in the 'growth of inward pressure' that would provide the readers with a better understanding and comprehension. Thus, option B is the correct answer.
