Answer:
C. A mass of air that is similar in temperature and humidity
Explanation:
An "air mass" refers to a big volume of air that is characterized by having similar or uniform "temperature" and "humidity"<em> (moisture).</em> They come from different source regions, thus they are classified accordingly.
The<em> "cold air masses"</em> come from the <u>polar area</u>s while the<em> "warm air masses"</em> come from the<u> tropical areas.</u> An air mass may cause a storm, for example, when an air mass moves to a new region and confronts another air mass there with a<em> different humidity and temperature</em>.
Answer:
Two stars (a and b) can have the same luminosity, but different surface area and temperature if the following condition is met:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
Explanation:
The luminosity of a star is the total energy that produces in one second. It depends on the size of the star and its surface temperature.
L = σ(T^4)(4πR^2)
L is the luminosity f the star, T is the temperature of the surface of the star and R is its radius.
Two stars can have the same luminosity if the relation between the radius and the surface temperature is maintained.
To see this lets suposed you have 2 stars, a and b, and the luminosities of each one of them:
L_a = σ(T_a^4)(4πR_a^2)
L_b = σ(T_b^4)(4πR_b^2)
you can assume that L_a and L_b are equal:
σ(T_a^4)(4πR_a^2) = σ(T_b^4)(4πR_b^2)
Now, you can cancel the constants:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
as long as this relation between a and b is true, then the luminosity can be the same.
C: 1, 2, 3 asia minor and anatolian are referred as the same
Answer:
It is partially true, "life finds a way" but human activities have already made some irreversible damage to the world.
Explanation:
In a Hypotethic scenario in which Humans are extinct nature Will eventually, start succession processes in urban areas and after many years depending on the erosional resistance of the materials nature will erase many of the buildings around the world ( 500 years for metal). Water bodies will eventually decontaminate trough the water cycle and be filled with organisms, contamination due to petrol can also be reverted through natural chemical processes with oxygen.
But human activities like mining are irreversible, for the earth, it is impossible to recover its shape, the materials already extracted and soil nutrients that ran out due to the use of chemicals.
The acceleration of the climate change due to human activities is for sure the biggest wound we have made to the world, this is an irreversible acceleration to a natural process.
