Answer:
in the mantle of the earth
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.
