Both raise and rise refer to something going up, but there is a difference:
Raise needs a direct object – if you raise something you move it up. It has both literal and non-literal meanings and it is a regular verb, so it’s past and past participle forms are raised.
- I raise my eyebrows when I’m surprised.
- The government plan to raise taxes.
- He raised his voice at me in anger, but I forgave him.
Rise does not take a direct object – things rise or go up by themselves. Rise is an irregular verb so the past form is rose and the past participle is risen.
- The sun rises at 6a.m.
- The water level rises twice a day because of the tide.
- The bird rose into the air and flew away.
