How did this pattern affect the voting power of the north and south in the u. s. senate?

The admission of these 4 states affected the voting power of slave and free states in the U.S. senate is because 3 of the states were free slave states and 1 of the states was a slave state. So that would probably mean that the free slave states would probably win against the slave states. Hope this helped!!

loess contribute to the flooding of rivers by providing the silt that is washed into rivers and constantly raises the bed of the rivers. this elevation above the surrounding flood plains and dams allow the river to overwhelm the dams and flood thousand of square miles of neighboring flood plains.
