What causes motion sickness?

During motion sickness, balance sensors in your inner ear and muscles send signals to the brain that don't match what your eyes are processing. For example, your eyes may see the landscape passing by at high speed, while your balance structures are sensing that you are sitting still. This confusing information is felt as motion sickness.
