<span>The correct answer is:
a. Economics is the social science that tries to explain the choices people make concerning the limited resources that meet their needs and wants.
Note that people also include the government - since governments are made up of people.
Now, the reason why the other options are wrong:
b. Economics is the social science that tries to explain the reasons why the currencies of various countries are so numerous.
The currencies are an instrument, but not a necessary one. For example, the traditional economies don't use currencies at all!
c. Economics is the social science that tries to explain only the choices the government makes concerning supply and demand in the markets.
Reason why it's wrong: It examines the choice of both private and official choices !
d. Economics is the social science that tries to explain the spiritual choices people make concerning how to share limited resources.
- this is false as spirituality barely matters in economics except as a factor influencing people's choices!</span>
Answer: The heat source for Earth’s atmosphere and oceans is the sun, which heats from above instead of below.
Explanation:
In the experiment, the source of heat is the burner below the pot. On Earth this is completely different as the source of the heat on Earth is the Sun which heats us from above instead of below.
The Convection currents still flow in the same direction however because as the sun heats air particles on Earth's surface, they rise but then cool as they keep going up. This makes them go back down where they are then heated up again.
Yes it is. you never know when someone could come flying around the corner, or where a cop is sitting.
