The velocity of a stream usually increases downstream. The gradient (slope) of the stream typically decreases but gravity, elimination of bed roughness and an increase in the amount of water from the entry of tributaries tends to increase the velocity.
False. they form slowly due to erosion and the minerals stay the same
Answer:
genetic modification competitors increase
