The sodium concentration is higher outside the cell than
inside the cell and the potassium concentration is higher inside the cell than
outside the cell.
Because the sodium-potassium exchange pump moves sodium and
potassium ions in opposite directions, the pump generates concentration
gradients for these ions that are opposite in direction.

Answer:
grinding
Explanation:
The streams are very powerful agents when it comes to erosion. With their power and chemical composition, the streams manage to erode the rocks easily and even the hardest rocks experience significant changes or are totally destroyed over time. The water of the streams manages to break down the rocks into small or big pieces, and as it does it moves them away. The rocks that are carried are constantly colliding with other rocks along the way, causing even more pieces to break and to be eroded, thus the grinding type of stream erosion.
