Oh yes, that is so true :)
The answer is B. folding, uplift, and erosion. certain mountains are created from the folding of the upper layers of earth's crust. valleys on the other hand are made from the erosion of land or soil. tectonic uplift of the earths crust is also responsible for creating mountains.
Characteristically, Command Economies are bad when it comes
to a person interested in making a profit; this is because they
typically center on economic equality and do not have economic efficiency. Speaking
in general, in a command economy, the allocation of resources is done by a
Central Planning Committee, and this system usually leads to quite a number of
shortages and/or surpluses in products since the demand/supply can be impulsive.<span> On the other hand, Market Economies are centered on profit-making
and Economic Efficiency.</span>
<span>
</span>
Essentially, how well resources are distributed among the
public will determine how well people will be rewarded. Let’s take for instance,
a parking lot like downtown; characteristically, a market economy will likely focus
on how to place as many cars as possible in the lot and how to use the space to
its full capacity, while a Command will most likely try to apportion the space
so that (just for example) 3 small, 3 medium and 3 large vehicles are parked (economic
equality).
<span>
<span>Finally, with a market economy, there is likely to
to be less shortages and less surpluses, since it works with the Law of Supply
and Demand in which an equilibrium price will be automatically established
through buying and selling.</span></span>
The crust is the part you walk on, and it's the surface of the earth.
<span>Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. This results in a continous circulation pattern. Water boiling in a pan is a good example of these convection currents. Another good example of convection is in the atmosphere. The earth's surface is warmed by the sun, the warm air rises and cool air moves in.
</span><span>Convection is the movement of heat through gases or liquids. Heat from the sun heats the air which can account for A and D, but a lot of the Earth's heat is distributed by the ocean. Water has a high specific heat which can absorb a lot of heat in one place, and distribute it in a colder place evening out the Earth's temperatures a bit.
</span>
So, the answer would be
<span>through the greenhouse effect
And could also be </span><span>through the movement of winds and currents</span>
