How do oxbow lakes form?

Rivers are dammed, and the water builds up, creating a lake.

Rivers wear away banks until the bank is broken and the river flows straight.

Glaciers leave deep channels in the ground, which fill with water and become a lake.

Which rocks will likely weather the least?

rocks that are soft

rocks with a porous surface

rocks that are in a dry climate

rocks with minerals that dissolve easily
