Remember!
A cause is something that makes something else happen. It's like the reason why something happens. For example, if you eat too much candy, the cause might be that you get a stomachache. So, eating too much candy is the cause of the stomachache.
On the other hand, an effect is what happens as a result of the cause. It's like what comes after the cause. So, in our example, the effect of eating too much candy is getting a stomachache.
So, cause is the reason why something happens, and effect is what happens as a result.
