Answer:
<u>D. Gradient decreases, discharge increases.</u>
Explanation:
- As steam is a body of water that carries rock particles and dissolved ions, discharge is measured in terms of volume/time (m3/sec). So when a river discharges its flow from a headwater to its mouth the velocity increases in the downstream direction.
- Thus the river load-carrying capacity increases downwards and so does the discharge rate. The discharge rate can also be influenced due to the rainfall patterns, volume of water and velocity of flow.
- Rock types also impact the streamflow if it is a porous rock, the surface will absorb more of moisture content and comparative more will be the water penetration towers the mouth of the flow.

B; As far as the relation between humans and the environment, it is obvious how much they relied on it. Not only as a food source, but for economic growth and sustainability as well. The other answers make valid points but in the context of this question, the only one that even mentions the relation is B.
Answer:
Afghanistan's mountains have kept the country from ever being invaded.
Explanation:
Afghanistan is a country in terrible conditions, and this is not the case just nowadays but it has been like that for a very long time. Despite all of the internal troubles of the country and it seems to be very weak in pretty much every sector, it has never been invaded in the past few centuries, and very rarely in the more distant history and always it has been short-lasting.
The main reason for this has been the mountains and the general geography of the country. Very high and rugged mountains are separating the country from potential invaders. Even if an invading force manages to go through the mountains, it will suffer great losses just by doing so, and what comes next is desert and more rugged terrain, which will further damage them, so by the time they engage in battle, they will be too weak to conquer Afghanistan.
